Airbus A321
–
The Airbus A321 is a member of the Airbus A320 family of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners manufactured by Airbus. It was the first derivative of the baseline Airbus A320 aircraft, final assembly of the aircraft takes place in Hamburg, Germany or Mobile, Alabama in the US. The A321 is a variant of the Airbus A320 and entered service in 1994 with Lufthansa. The aircraft shares a type rating with all other Airbus A320 family variants. As of 28 February 2017, a total of 1,461 Airbus A321 aircraft have been delivered, in addition, another 275 airliners are on firm order. As of February 2017, American Airlines was the largest operator of the Airbus A321, in December 2010, Airbus announced a new generation of the A320 family, the A320neo. The similarly lengthened fuselage A321neo variant offers new, more efficient engines, combined with airframe improvements, the aircraft will deliver fuel savings of up to 15%. The A321neo has total orders for 1,384 aircraft as of 28 February 2017, the Airbus A321 was the first derivative of the A320, also known as the Stretched A320, A320-500 and A325. Its launch came on 24 November 1988, around the time as the A320 entered service. The aircraft would be a derivative, apart from a number of minor modifications to the wing. The wing would incorporate double-slotted flaps and minor trailing edge modifications, the fuselage was lengthened by four plugs, giving the A321 an overall length of 6.94 metres longer than the A320. This is achieved by adding a 4.27 m front plug immediately forward of wing, to maintain performance, double-slotted flaps were included, in addition to increasing the wing area by 4 m2, to 128 m2. Other minor modifications were made to accommodate the A321-100s 9,600 kg increase in takeoff weight to 83,000 kg. The length increase required the overwing exits of the A320 to be enlarged and repositioned in front of, the A321 is the largest variant of the A320 family. The centre fuselage and undercarriage were reinforced to accommodate the increase in takeoff weight of 9,600 kg. Lufthansa and Alitalia were the first to order the stretched Airbuses, with 20 and 40 aircraft requested, the first of Lufthansas V2500-A5-powered A321s arrived on 27 January 1994, while Alitalia received its first CFM56-5B-powered aircraft on 22 March 1994. The A321-100 entered service in January 1994 with Lufthansa, final assembly for the A321 would be, as a first for any Airbus, carried out in Germany. The second production line was located at Hamburg, which would subsequently produce the smaller Airbus A319

Assembly line
–
Assembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and electronic goods. Assembly lines are designed for the organization of workers, tools or machines. The motion of workers is minimized to the extent possible, all parts or assemblies are handled either by conveyors or motorized vehicles such as fork lifts, or gravity, with no manual trucking. Heavy lifting is done by such as overhead cranes or fork lifts. Each worker typically performs one simple operation, use sliding assembling lines by which the parts to be assembled are delivered at convenient distances. Consider the assembly of a car, assume that certain steps in the line are to install the engine, install the hood. In traditional production, only one car would be assembled at a time, if engine installation takes 20 minutes, hood installation takes five minutes, and wheels installation takes 10 minutes, then a car can be produced every 35 minutes. In an assembly line, car assembly is split between several stations, all working simultaneously, when one station is finished with a car, it passes it on to the next. By having three stations, a total of three different cars can be operated on at the time, each one at a different stage of its assembly. After finishing its work on the first car, the installation crew can begin working on the second car. While the engine installation crew works on the car, the first car can be moved to the hood station and fitted with a hood, then to the wheels station. After the engine has been installed on the car, the second car moves to the hood assembly. At the same time, the car moves to the engine assembly. When the third car’s engine has been mounted, it then can be moved to the station, meanwhile. Before the Industrial Revolution, most manufactured products were made individually by hand, a single craftsman or team of craftsmen would create each part of a product. They would use their skills and tools such as files and knives to create the individual parts and they would then assemble them into the final product, making cut-and-try changes in the parts until they fit and could work together. Adam Smith discussed the division of labour in the manufacture of pins at length in his book The Wealth of Nations, the Venetian Arsenal, dating to about 1104, operated similar to a production line. Ships moved down a canal and were fitted by the various shops they passed, although the Venice Arsenal lasted until the early Industrial Revolution, production line methods did not become common even then

Hamburg Finkenwerder Airport
–
Hamburg Finkenwerder Airport is a private airport in the quarter of Finkenwerder, in the southwest part of Hamburg, Germany. It is part of the Hamburg plant of Airbus and is used by them for corporate, freight, test. Finkenwerder is fully able to handle the Airbus A380 and it should not be confused with Hamburg Fuhlsbüttel Airport, the citys international airport. The airfield was built about 10 years after World War II, in 1964 the third prototype of the Transall C-160 made its first flight from the airport. Beginning in April 2006, the runway was extended from 2,684 m to 3,183 m at the southern end, on 16 July 2007, the extended runway was handed over after completion of works to Airbus, around two months ahead of schedule. The airport is part of the Airbus facility in Hamburg, where around 15,000 people are employed, final assembly for all models of the A320 family takes place here, and both the A320 and A380 are fitted with their cabin interiors and painted for final delivery. In addition, final acceptance and delivery of A380s for customers in Europe, the Hamburg factory is also home to Airbus’ A380 major component assembly hall, which houses the structural assembly and the fitting-with equipment of the forward and complete rear fuselage sections. These sections are shipped to France on a specially built ferry. A large spares centre is maintained at Hamburg, and A320 Family maintenance training facilities can also be found on-site. Hamburg also plays a key role in the A330 and A350 XWB programmes, for which it manufactures and equips the forward, there are no public flights to and from the airport. Besides transfer, freight and test flights for Airbus there is a twice daily corporate shuttle service from here to Airbus plant in Toulouse, the airport handles around 10 to 15 aircraft movements per day

NASA
–
President Dwight D. Eisenhower established NASA in 1958 with a distinctly civilian orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29,1958, disestablishing NASAs predecessor, the new agency became operational on October 1,1958. Since that time, most US space exploration efforts have led by NASA, including the Apollo Moon landing missions, the Skylab space station. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the agency is also responsible for the Launch Services Program which provides oversight of launch operations and countdown management for unmanned NASA launches. NASA shares data with various national and international such as from the Greenhouse Gases Observing Satellite. Since 2011, NASA has been criticized for low cost efficiency, from 1946, the National Advisory Committee for Aeronautics had been experimenting with rocket planes such as the supersonic Bell X-1. In the early 1950s, there was challenge to launch a satellite for the International Geophysical Year. An effort for this was the American Project Vanguard, after the Soviet launch of the worlds first artificial satellite on October 4,1957, the attention of the United States turned toward its own fledgling space efforts. This led to an agreement that a new federal agency based on NACA was needed to conduct all non-military activity in space. The Advanced Research Projects Agency was created in February 1958 to develop technology for military application. On July 29,1958, Eisenhower signed the National Aeronautics and Space Act, a NASA seal was approved by President Eisenhower in 1959. Elements of the Army Ballistic Missile Agency and the United States Naval Research Laboratory were incorporated into NASA, earlier research efforts within the US Air Force and many of ARPAs early space programs were also transferred to NASA. In December 1958, NASA gained control of the Jet Propulsion Laboratory, NASA has conducted many manned and unmanned spaceflight programs throughout its history. Some missions include both manned and unmanned aspects, such as the Galileo probe, which was deployed by astronauts in Earth orbit before being sent unmanned to Jupiter, the experimental rocket-powered aircraft programs started by NACA were extended by NASA as support for manned spaceflight. This was followed by a space capsule program, and in turn by a two-man capsule program. This goal was met in 1969 by the Apollo program, however, reduction of the perceived threat and changing political priorities almost immediately caused the termination of most of these plans. NASA turned its attention to an Apollo-derived temporary space laboratory, to date, NASA has launched a total of 166 manned space missions on rockets, and thirteen X-15 rocket flights above the USAF definition of spaceflight altitude,260,000 feet. The X-15 was an NACA experimental rocket-powered hypersonic research aircraft, developed in conjunction with the US Air Force, the design featured a slender fuselage with fairings along the side containing fuel and early computerized control systems

Aeronomy of Ice in the Mesosphere
–
The Aeronomy of Ice in the Mesosphere is a satellite to conduct a 26-month study of noctilucent clouds. It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program, on April 25,2007 AIM was boosted into a 600 km high polar orbit by a Pegasus-XL rocket, which was air-launched from the Lockheed L-1011 Stargazer aircraft operated by Orbital Sciences. The AIM satellite is a 200 kg,1.4 m by 1, the AIM mission will help determine what factors — temperature, water vapor, and dust particles — lead to the formation of these clouds. The clouds seem to be a recent phenomenon, they were first seen in 1885. The clouds always occur during the season near the poles. Scientists have found that the start of the Southern season can vary up to a month however, AIM home SOFIE Instrument and science description, view or download data AIM Mission Profile by NASAs Solar System Exploration

Satellite
–
In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are called artificial satellites to distinguish them from natural satellites such as Earths Moon. In 1957 the Soviet Union launched the worlds first artificial satellite, since then, about 6,600 satellites from more than 40 countries have been launched. According to a 2013 estimate,3,600 remained in orbit, of those, about 1,000 were operational, the rest have lived out their useful lives and become space debris. Approximately 500 operational satellites are in orbit,50 are in medium-Earth orbit. A few large satellites have been launched in parts and assembled in orbit. Over a dozen space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, a few asteroids, Satellites are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, well-known classes include low Earth orbit, polar orbit, and geostationary orbit. A launch vehicle is a rocket that throws a satellite into orbit, usually it lifts off from a launch pad on land. Some are launched at sea from a submarine or a mobile maritime platform, Satellites are usually semi-independent computer-controlled systems. Satellite subsystems attend many tasks, such as power generation, thermal control, telemetry, attitude control, the first fictional depiction of a satellite being launched into orbit was a short story by Edward Everett Hale, The Brick Moon. The idea surfaced again in Jules Vernes The Begums Fortune, in 1903, Konstantin Tsiolkovsky published Exploring Space Using Jet Propulsion Devices, which is the first academic treatise on the use of rocketry to launch spacecraft. He calculated the speed required for a minimal orbit. In 1928, Herman Potočnik published his book, The Problem of Space Travel — The Rocket Motor. He described the use of orbiting spacecraft for observation of the ground, in a 1945 Wireless World article, the English science fiction writer Arthur C. Clarke described in detail the possible use of communications satellites for mass communications. He suggested that three geostationary satellites would provide coverage over the entire planet, the first artificial satellite was Sputnik 1, launched by the Soviet Union on October 4,1957, and initiating the Soviet Sputnik program, with Sergei Korolev as chief designer. This in turn triggered the Space Race between the Soviet Union and the United States, Sputnik 1 helped to identify the density of high atmospheric layers through measurement of its orbital change and provided data on radio-signal distribution in the ionosphere

Cleanroom
–
More accurately, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. The modern cleanroom was invented by American physicist Willis Whitfield, as employee of the Sandia National Laboratories, Whitfield created the initial plans for the cleanroom in 1960. Prior to Whitfields invention, earlier cleanrooms often had problems with particles, Whitfield designed his cleanroom with a constant, highly filtered air flow to flush out impurities. Within a few years of its invention in the 1960s, Whitfields modern cleanroom had generated more than 50 billion USD in sales worldwide, entire manufacturing facilities can be contained within a cleanroom with factory floors covering thousands of square meters. They are used extensively in manufacturing, biotechnology, the life sciences. Staff enter and leave through airlocks, and wear protective clothing such as hoods, face masks, gloves, boots, equipment inside the cleanroom is designed to generate minimal air contamination. Only special mops and buckets are used, cleanroom furniture is designed to produce a minimum of particles and to be easy to clean. Common materials such as paper, pencils, and fabrics made from natural fibers are often excluded, cleanrooms are not sterile, only airborne particles are controlled. Particle levels are tested using a particle counter and microorganisms detected and counted through environmental monitoring methods. Some cleanrooms are kept at a positive pressure so if any leaks occur, some cleanroom HVAC systems control the humidity to low levels, such that extra equipment is necessary to prevent electrostatic discharge problems. Low-level cleanrooms may only require special shoes, with completely smooth soles that do not track in dust or dirt, however, for safety reasons, shoe soles must not create slipping hazards. Access to a cleanroom is usually restricted to wearing a cleanroom suit. In cleanrooms in which the standards of air contamination are less rigorous, an anteroom is used to put on clean-room clothing. Some manufacturing facilities do not use fully classified cleanrooms, but use some cleanroom practices to maintain their contamination requirements, cleanrooms maintain particulate-free air through the use of either HEPA or ULPA filters employing laminar or turbulent air flow principles. Laminar air flow systems are employed across 80% of a cleanroom ceiling to maintain constant air processing. Stainless steel or other non shedding materials are used to construct laminar air flow filters, turbulent, or non unidirectional, air flow uses both laminar air flow hoods and nonspecific velocity filters to keep air in a cleanroom in constant motion, although not all in the same direction. The rough air seeks to trap particles that may be in the air and drive them towards the floor, US FDA and EU have laid down guidelines and limit for microbial contamination which is very stringent to ensure freedom from microbial contamination in pharmaceutical products. In the healthcare and pharmaceutical sectors, control of microorganisms is important, studying cleanroom microflora is of importance for microbiologists and quality control personnel to assess changes in trends

Harmony (ISS module)
–
Harmony, also known as Node 2, is the utility hub of the International Space Station. The hub contains four racks that provide power, plus electronic data. Harmony was successfully launched into space aboard Space Shuttle flight STS-120 on October 23,2007, after temporarily being attached to the port side of the Unity node, it was moved to its permanent location on the forward end of the Destiny laboratory on November 14,2007. The unit formerly known as Node 2 was renamed Harmony in March 2007, the name was chosen from a competition involving more than 2,200 kindergarten through high school students from 32 US states. Weighing approximately 14,288 kilograms, Harmony is the second of three node module on USOS, the design is based on the existing Multi-Purpose Logistics Module, as well as the European Space Agencys Columbus Module. There are six Common Berthing Mechanisms on Harmony, the one that connects it to Destiny is passive, Harmony is managed by NASAs Marshall Space Flight Center in Huntsville, Alabama. The Space Station robotic arm, Canadarm2, is able to operate from a powered grapple fixture on the exterior of Harmony. After the cancellation of the Habitation Module, Harmony was chosen to house the American Crew Quarters, the first two were delivered on STS-126 and the second two on STS-128. The node measures 7.2 metres in length, and it has a diameter of 4.4 metres, in an agreement between NASA and the European Space Agency the Rome-based company Thales Alenia Space built Harmony at its facility in Turin, Italy. Harmony arrived on June 1,2003 at the Kennedy Space Center in Florida after its flight in an Airbus Beluga oversize cargo vehicle, following post transportation inspection, the Italian Space Agency formally handed over Harmony to the European Space Agency. From there, ESA formally transferred ownership of Harmony to NASA on June 18,2003, the handover of Harmony completed a major element of the barter agreement, between ESA and NASA, that was signed in Turin on October 8,1997. Paolo A. Nespoli, an ESA astronaut born in Milan, Italy, Harmony was launched October 23,2007 aboard STS-120, as the primary component of assembly mission ISS-10A. After the Space Shuttle departed Harmony was relocated to the dock of the Destiny laboratory. It required three EVAs by the crew to complete the installation. Harmony was the first permanent living space enlargement to the ISS after the Pirs docking compartment was added in 2001, the Expedition 16 crew moved the Pressurized Mating Adapter on November 12,2007 from the Destiny Laboratory to the forward berth of Harmony. The combined PMA-2/Harmony unit was subsequently berthed to its destination at the forward end of the Destiny Laboratory on November 14,2007. All the following Space Shuttle missions would be docked to this location, on February 11,2008, ESAs Columbus laboratory was attached to the starboard hatch of the Harmony module during space shuttle mission STS-122. On March 14,2008 the Experiment Logistics Module Pressurized Section of Kibō was attached to its interim location, the zenith hatch of Harmony

International Space Station
–
The International Space Station is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest man-made body in space, the ISS consists of pressurised modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets, the ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of systems and equipment required for missions to the Moon. The ISS maintains an orbit with an altitude of between 330 and 435 km by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft and it completes 15.54 orbits per day. The ISS is the space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz. The station has continuously occupied for 16 years and 156 days since the arrival of Expedition 1 on 2 November 2000. This is the longest continuous presence in low Earth orbit. It has been visited by astronauts, cosmonauts and space tourists from 17 different nations, Soyuz has very limited downmass capability. The ISS programme is a joint project among five participating space agencies, NASA, Roscosmos, JAXA, ESA, the ownership and use of the space station is established by intergovernmental treaties and agreements. The station is divided two sections, the Russian Orbital Segment and the United States Orbital Segment, which is shared by many nations. As of January 2014, the American portion of ISS is being funded until 2024, Roscosmos has endorsed the continued operation of ISS through 2024 but has proposed using elements of the Russian Orbital Segment to construct a new Russian space station called OPSEK. On 28 March 2015, Russian sources announced that Roscosmos and NASA had agreed to collaborate on the development of a replacement for the current ISS. NASA later issued a statement expressing thanks for Russias interest in future co-operation in space exploration. According to the original Memorandum of Understanding between NASA and Rosaviakosmos, the International Space Station was intended to be a laboratory, observatory and factory in low Earth orbit. It was also planned to provide transportation, maintenance, and act as a base for possible future missions to the Moon, Mars. In the 2010 United States National Space Policy, the ISS was given roles of serving commercial, diplomatic. The ISS provides a platform to conduct scientific research, the ISS simplifies individual experiments by eliminating the need for separate rocket launches and research staff

Aircraft design process
–
The aircraft design process is the engineering design process by which aircraft are designed. These depend on factors such as customer and manufacturer demand, safety protocols, physical. For some types of aircraft the design process is regulated by national airworthiness authorities and this article deals with powered aircraft such as airplanes and helicopter designs. Aircraft design is a compromise between competing factors and constraints and accounts for existing designs and market requirements to produce the best aircraft. The design process starts with the intended purpose. The purpose may be to fit a specific requirement, e. g, another important factor that influences the design of the aircraft are the regulations put forth by national aviation airworthiness authorities. Airports may also impose limits on aircraft, for instance, the maximum allowed for a conventional aircraft is 80 m to prevent collisions between aircraft while taxiing. Budget limitations, market requirements and competition set constraints on the design process, competition leads to companies striving for better efficiency in the design without compromising performance and incorporating new techniques and technology. An increase in the number of aircraft also means greater carbon emissions, environmental scientists have voiced concern over the main kinds of pollution associated with aircraft, mainly noise and emissions. Noise also arises from the airframe, where the directions are changed. Improved noise regulations have forced designers to create engines and airframes. Emissions from aircraft include particulates, carbon dioxide, Sulfur dioxide, Carbon monoxide, various oxides of nitrates, to combat the pollution, ICAO set recommendations in 1981 to control aircraft emissions. Newer, environmentally friendly fuels have been developed and the use of materials in manufacturing have helped reduce the ecological impact due to aircraft. Environmental limitations also affect airfield compatibility, airports around the world have been built to suit the topography of the particular region. Space limitations, pavement design, runway end safety areas and the location of airport are some of the airport factors that influence aircraft design. The high speeds, fuel tanks, atmospheric conditions at altitudes, natural hazards. Airworthiness is the standard by which aircraft are determined fit to fly, the responsibility for airworthiness lies with national aviation regulatory bodies, manufacturers, as well as owners and operators. Every country has its own body such as the Federal Aviation Authority in USA, DGCA in India

Aircraft
–
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the lift of an airfoil. The human activity that surrounds aircraft is called aviation, crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as type, aircraft propulsion, usage. Each of the two World Wars led to technical advances. Consequently, the history of aircraft can be divided into five eras, Pioneers of flight, first World War,1914 to 1918. Aviation between the World Wars,1918 to 1939, Second World War,1939 to 1945. Postwar era, also called the jet age,1945 to the present day, aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, a balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. – though none had yet been built, the advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by an outer framework and separate aerodynamic skin surrounding the gas bags, were produced. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a balloon is an aerostat and an airship is a powered one. A powered, steerable aerostat is called a dirigible, sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship. Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back and these soon became known as blimps. During the Second World War, this shape was adopted for tethered balloons, in windy weather

Missile
–
In modern language, a missile is a self-propelled precision-guided munition system, as opposed to an unguided self-propelled munition, referred to as a rocket. Missiles have four components, targeting and/or missile guidance, flight system, engine. Missiles come in types adapted for different purposes, surface-to-surface and air-to-surface missiles, surface-to-air missiles, air-to-air missiles, all known existing missiles are designed to be propelled during powered flight by chemical reactions inside a rocket engine, jet engine, or other type of engine. Non-self-propelled airborne explosive devices are referred to as shells and usually have a shorter range than missiles. In ordinary British-English usage predating guided weapons, a missile is any thrown object, the word missile comes from the Latin verb mittere, meaning to send. In military usage, munitions projected towards a target are broadly categorised as follows, a powered, unguided munition is known as a rocket. Unpowered munitions not fired from a gun are called bombs whether guided or not, munitions that are fired from a gun are known as projectiles whether guided or not. If explosive, they are more specifically as shells or mortar bombs. Powered munitions that travel through water are called torpedoes, hand grenades are not usually classed as missiles. The first missiles to be used operationally were a series of missiles developed by Nazi Germany in World War II, most famous of these are the V-1 flying bomb and V-2 rocket, both of which used a simple mechanical autopilot to keep the missile flying along a pre-chosen route. Less well known were a series of anti-shipping and anti-aircraft missiles, however, these early systems in World War II were only built in small numbers. Guided missiles have a number of different system components, Targeting and/or missile guidance Flight system Engine Warhead Missiles may be targeted in a number of ways. The most common method is to use some form of radiation, such as infrared, lasers or radio waves and this radiation may emanate from the target, it may be provided by the missile itself, or it may be provided by a friendly third party. The first two are known as fire-and-forget as they need no further support or control from the launch vehicle/platform in order to function. Another method is to use a TV guidance—using either visible light or infrared—in order to see the target, the picture may be used either by a human operator who steers the missile onto its target or by a computer doing much the same job. One of the more bizarre guidance methods instead used a pigeon to steer the missile to its target, many missiles use a combination of two or more of the above methods to improve accuracy and the chances of a successful engagement. Another method is to target the missile by knowing the location of the target and using a system such as INS. This guidance system guides the missile by knowing the current position and the position of the target

Rocket
–
A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use, Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space. In fact, rockets work more efficiently in space than in an atmosphere, multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin. Rockets for military and recreational uses date back to at least 13th century China, significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology for the Space Age, including setting foot on the Earths moon. Rockets are now used for fireworks, weaponry, ejection seats, launch vehicles for satellites, human spaceflight. Chemical rockets are the most common type of high power rocket, chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimizes risks, the first gunpowder-powered rockets were developed in Song China, by the 13th century. The Chinese rocket technology was adopted by the Mongols and the invention was spread via the Mongol invasions to the Near East, medieval and early modern rockets were used militarily as incendiary weapons in sieges. An early Chinese text to mention the use of rockets was the Huolongjing, between 1270 and 1280, Hasan al-Rammah wrote al-furusiyyah wa al-manasib al-harbiyya, which included 107 gunpowder recipes,22 of which are for rockets. In Europe, Konrad Kyeser described rockets in his military treatise Bellifortis around 1405. The name Rocket comes from the Italian rocchetta, meaning bobbin or little spindle, the Italian term was adopted into German in the mid 16th century by Leonhard Fronsperger and Conrad Haas, and by the early 17th century into English. Artis Magnae Artilleriae pars prima, an important early work on rocket artillery. The first iron-cased rockets were developed in the late 18th century in the Kingdom of Mysore, in 1814, Francis Scott Key wrote the line rockets red glare while held captive on a British ship that was laying siege to Fort McHenry. The first mathematical treatment of the dynamics of rocket propulsion is due to William Moore, in 1815, Alexander Dmitrievich Zasyadko constructed rocket-launching platforms, which allowed rockets to be fired in salvos, and gun-laying devices. William Hale in 1844 greatly increased the accuracy of rocket artillery, the Congreve rocket was further improved by Edward Mounier Boxer in 1865. Konstantin Tsiolkovsky first speculated on the possibility of manned spaceflight with rocket technology, robert Goddard in 1920 published proposed improvements to rocket technology in A Method of Reaching Extreme Altitudes

Spacecraft
–
A spacecraft is a vehicle, or machine designed to fly in outer space. Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, space colonization, planetary exploration, on a sub-orbital spaceflight, a spacecraft enters space and then returns to the surface, without having gone into an orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies, robotic spacecraft used to support scientific research are space probes. Robotic spacecraft that remain in orbit around a body are artificial satellites. Only a handful of interstellar probes, such as Pioneer 10 and 11, Voyager 1 and 2, orbital spacecraft may be recoverable or not. By method of reentry to Earth they may be divided in non-winged space capsules, Sputnik 1 was the first artificial satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957, the launch ushered in new political, military, technological, and scientific developments, while the Sputnik launch was a single event, it marked the start of the Space Age. Apart from its value as a technological first, Sputnik 1 also helped to identify the upper atmospheric layers density and it also provided data on radio-signal distribution in the ionosphere. Pressurized nitrogen in the satellites false body provided the first opportunity for meteoroid detection, Sputnik 1 was launched during the International Geophysical Year from Site No. 1/5, at the 5th Tyuratam range, in Kazakh SSR. The satellite travelled at 29,000 kilometers per hour, taking 96.2 minutes to complete an orbit and this altitude is called the Kármán line. In particular, in the 1940s there were several test launches of the V-2 rocket, as of 2016, only three nations have flown manned spacecraft, USSR/Russia, USA, and China. The first manned spacecraft was Vostok 1, which carried Soviet cosmonaut Yuri Gagarin into space in 1961, there were five other manned missions which used a Vostok spacecraft. The second manned spacecraft was named Freedom 7, and it performed a sub-orbital spaceflight in 1961 carrying American astronaut Alan Shepard to an altitude of just over 187 kilometers, there were five other manned missions using Mercury spacecraft. Other Soviet manned spacecraft include the Voskhod, Soyuz, flown unmanned as Zond/L1, L3, TKS, China developed, but did not fly Shuguang, and is currently using Shenzhou. Except for the shuttle, all of the recoverable manned orbital spacecraft were space capsules. Manned space capsules The International Space Station, manned since November 2000, is a joint venture between Russia, the United States, Canada and several other countries, some reusable vehicles have been designed only for manned spaceflight, and these are often called spaceplanes. The first example of such was the North American X-15 spaceplane, the first reusable spacecraft, the X-15, was air-launched on a suborbital trajectory on July 19,1963. The first partially reusable spacecraft, a winged non-capsule, the Space Shuttle, was launched by the USA on the 20th anniversary of Yuri Gagarins flight

Aerospace
–
Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth and surrounding space. Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft, Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace is not the same as airspace, which is the air space directly above a location on the ground. In most industrial countries, the industry is a cooperation of public. Along with these public space programs, many companies produce technical tools and components such as spaceships, some known companies involved in space programs include Boeing, Airbus Group, SpaceX, Lockheed Martin, MacDonald Dettwiler and Northrop Grumman. These companies are involved in other areas of aerospace such as the construction of aircraft. Modern aerospace began with George Cayley in 1799, Cayley proposed an aircraft with a fixed wing and a horizontal and vertical tail, defining characteristics of the modern airplane. Airmen like Otto Lilienthal, who introduced cambered airfoils in 1891, the Wright brothers were interested in Lilienthals work and read several of his publications. They also found inspiration in Octave Chanute, an airman and the author of Progress in Flying Machines, war and science fiction inspired great minds like Konstantin Tsiolkovsky and Wernher von Braun to achieve flight beyond the atmosphere. The launch of Sputnik 1 in October 1957 started the Space Age, in April 1981, the Space Shuttle Columbia launched, the start of regular manned access to orbital space. A sustained human presence in space started with Mir in 1986 and is continued by the International Space Station. Space commercialization and space tourism are more recent focuses in aerospace, Aerospace manufacturing is a high-technology industry that produces aircraft, guided missiles, space vehicles, aircraft engines, propulsion units, and related parts. Most of the industry is geared toward governmental work, for each original equipment manufacturer, the US government has assigned a Commercial and Government Entity code. These codes help to each manufacturer, repair facilities. In the United States, the Department of Defense and the National Aeronautics, others include the very large airline industry. The aerospace industry employed 472,000 wage and salary workers in 2006, most of those jobs were in Washington state and in California, with Missouri, New York and Texas also being important. The leading aerospace manufacturers in the U. S. are Boeing, United Technologies Corporation, SpaceX, Northrop Grumman and these manufacturers are facing an increasing labor shortage as skilled U. S. workers age and retire. In India, Bangalore is a center of the aerospace industry, where Hindustan Aeronautics Limited, the National Aerospace Laboratories

High tech
–
High technology, often abbreviated to high tech is technology that is at the cutting edge, the most advanced technology available. As of the onset of the 21st century, products considered high tech are often those that incorporate advanced computer electronics, the opposite of high tech is low technology, referring to simple, often traditional or mechanical technology, for example, a calculator is a low-tech calculating device. Perhaps the first occurrence of the phrase is in a 1958 The New York Times story advocating atomic energy for Europe, western Europe, with its dense population and its high technology. By 1969, Robert Metz was using it in a financial column, Metz used the term frequently thereafter, a few months later he was using it with a hyphen, saying that a fund holds computer peripheral. Business equipment, and high-technology stocks, and in a 1971 article in its first occurrence in the abbreviated form high tech, because the high-tech sector of the economy develops or uses the most advanced technology known, it is often seen as having the most potential for future growth. This perception has led to investment in high-tech sectors of the economy. High tech is often viewed as high risk, but offering the opportunity for high profits, like Big Science, high technology is an international phenomenon, spanning continents, epitomized by the worldwide communication of the Internet. There are several high technology definitions that can be found, moreover, there are many problems with identifying high technology. There are large diversity of definitions that are used, here is a short overview of a number of different techniques to define high technology. OECD has two different approaches, sector and product, the sector approach classifies industries according their technology intensity, product approach according to finished products. The OECD does not only take the manufacturing but also the rate of technology into account. The OECDs classification is as follows, Furthermore, OECD’s product-based classification supports the technology intensity approach and it can be concluded that companies in a high-tech industry do not necessarily produce high-tech products and vice versa. When speaking of a society in a non-literal way, it is usually in reference to an overall society based in high-tech. However, this is something generally unattainable by the definition comprising its scarcity among every technology available, one website, belonging to Carver Networks, owned by entrepreneur and founder Kimberly Carver, adopted the term as a legal name in June 2012. An organizations department dealing with the latest technology in their projects, may also be considered a high-tech microsociety within the organizations, students and faculty related with ENAEE or ABET accredited programs might be considered high-tech society members, regarding other traditional degrees. In industry, companies working in the edge may be considered high-tech societies along with its main competitors. Low technology Intermediate technology - sometimes used to technology between low and high technology Industrial design List of emerging technologies

Industry
–
Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry, when a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and this came through many successive rapid advances in technology, such as the production of steel and coal. Following the Industrial Revolution, possibly a third of the economic output are derived that is from manufacturing industries. Many developed countries and many developing/semi-developed countries depend significantly on manufacturing industry, Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web of interdependence. Industries can be classified in a variety of ways, at the top level, industry is often classified according to the three-sector theory into sectors, primary, secondary, and tertiary. Some authors add quaternary or even quinary sectors, over time, the fraction of a societys industry within each sector changes. Below the economic sectors there are other more detailed industry classifications. These classification systems commonly divide industries according to functions and markets. Market-based classification systems such as the Global Industry Classification Standard and the Industry Classification Benchmark are used in finance, the International Standard Industrial Classification of all economic activities is the most complete and systematic industrial classification made by the United Nations Statistics Division. ISIC is a classification of economic activities arranged so that entities can be classified according to the activity they carry out. The Industrial Revolution led to the development of factories for large-scale production, originally the factories were steam-powered, but later transitioned to electricity once an electrical grid was developed. The mechanized assembly line was introduced to parts in a repeatable fashion. This led to significant increases in efficiency, lowering the cost of the end process, later automation was increasingly used to replace human operators. This process has accelerated with the development of the computer and the robot, historically certain manufacturing industries have gone into a decline due to various economic factors, including the development of replacement technology or the loss of competitive advantage. An example of the former is the decline in manufacturing when the automobile was mass-produced. A recent trend has been the migration of prosperous, industrialized nations towards a post-industrial society and this is manifested by an increase in the service sector at the expense of manufacturing, and the development of an information-based economy, the so-called informational revolution. In a post-industrial society, manufacturing is relocated to more favourable locations through a process of off-shoring

Aviation
–
Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word aviation was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb avier, itself derived from the Latin word avis and the suffix -ation. The modern age of aviation began with the first untethered human lighter-than-air flight on November 21,1783, the practicality of balloons was limited because they could only travel downwind. It was immediately recognized that a steerable, or dirigible, balloon was required, jean-Pierre Blanchard flew the first human-powered dirigible in 1784 and crossed the English Channel in one in 1785. Rigid airships became the first aircraft to transport passengers and cargo over great distances, the best known aircraft of this type were manufactured by the German Zeppelin company. The most successful Zeppelin was the Graf Zeppelin and it flew over one million miles, including an around-the-world flight in August 1929. However, the dominance of the Zeppelins over the airplanes of that period, the Golden Age of the airships ended on May 6,1937 when the Hindenburg caught fire, killing 36 people. The cause of the Hindenburg accident was blamed on the use of hydrogen instead of helium as the lift gas. An internal investigation by the manufacturer revealed the coating used to protect the material over the frame was highly flammable. Changes to the coating formulation reduced the risk of further Hindenburg type accidents, although there have been periodic initiatives to revive their use, airships have seen only niche application since that time. In 1799 Sir George Cayley set forth the concept of the airplane as a fixed-wing flying machine with separate systems for lift, propulsion. Seven years later, on 14 October 1897, Aders Avion III was tested without success in front of two officials from the French War ministry, the report on the trials was not publicized until 1910, as they had been a military secret. In November 1906 Ader claimed to have made a flight on 14 October 1897. Although widely believed at the time, these claims were later discredited, however, the most widely accepted date is December 17,1903 by the Wright brothers. The Wright brothers were the first to fly in a powered and controlled aircraft, previous flights were gliders or free flight, but the Wright brothers combined both, setting the new standard in aviation records. Aircraft began to transport people and cargo as designs grew larger, the Wright brothers took aloft the first passenger, Charles Furnas, one of their mechanics, on May 14,1908. By the beginning of World War II, many towns and cities had built airports, the war brought many innovations to aviation, including the first jet aircraft and the first liquid-fueled rockets. Manufacturers such as Cessna, Piper, and Beechcraft expanded production to provide aircraft for the new middle-class market

Civil aviation
–
Civil aviation is one of two major categories of flying, representing all non-military aviation, both private and commercial. S. GA carries 166 million passengers each year, more than any individual airline, since 2004, the US Airlines combined have carried over 600 million passengers each year, and in 2014, they carried a combined 662,819,232 passengers. All scheduled air transport is commercial, but general aviation can be commercial or private. Normally, the pilot, aircraft, and operator must all be authorized to perform commercial operations through separate commercial licensing, registration, after World War Ⅱ, commercial aviation grew rapidly, using mostly ex-military aircraft to transport people and cargo. This growth was accelerated by the glut of heavy and super-heavy bomber airframes like the B-29, the DC-3 were also made for easier and longer commercial flights. The first commercial jet airliner to fly was the British de Havilland Comet, by 1952, the British state airline BOAC had introduced the Comet into scheduled service. While a technical achievement, the plane suffered a series of highly public failures, the fatigue was caused by cycles of pressurization and depressurization of the cabin, and eventually led to catastrophic failure of the planes fuselage. By the time the problems were overcome, other jet airliner designs had already taken to the skies, flight operations — carrying out safety oversight of commercial operators. Airworthiness — issuing certificates of registration and certificates of airworthiness to civil aircraft, aerodromes — designing and constructing aerodrome facilities. Air traffic services — managing the traffic inside of a countrys airspace, the World Bank lists monotonously growing numbers for the number of passengers transported per year world wide with a preliminary all-time high in 2015 of 3.44 billion passengers. Likewise, the number of registered carrier departures worldwide has reached a peak in 2015 with almost 33 billion takeoffs, the global seasonally adjusted revenue passenger kilometers per month peaked at more than 550 billion kilometres in January 2016, a 7% rise over one year

Military aviation
–
Airpower includes the national means of conducting such warfare, including the intersection of transport and war craft. Military aircraft include bombers, fighters, transports, trainer aircraft, the first military uses of aviation involved lighter-than-air balloons. During the Battle of Fleurus in 1794, the French observation balloon lEntreprenant was used to monitor Austrian troop movements, the use of lighter-than-air aircraft in warfare became prevalent in the 19th century, including regular use in the American Civil War. Lighter-than-air military aviation persisted until shortly after World War II, gradually being withdrawn from various roles as heavier-than-air aircraft improved, heavier-than-air aircraft were recognized as having military applications early on, despite resistance from traditionalists and the severe limitations of early aircraft. The U. S. Army Signal Corps purchased a Wright Model A on 2 August 1909 which became the first military aircraft in history, in 1911, the Italians used a variety of aircraft types in reconnaissance, photo-reconnaissance, and bombing roles during the Italo-Turkish War. The Turks, lacking anti-aircraft weapons, were the first to shoot down an aeroplane by rifle fire, technological improvements were made at a frenzied pace, and the first all-metal cantilevered airplanes were going into service as the war ended. The Allies would later use rocket-equipped fighters in the role, immobilizing German armored divisions during the Battle of Normandy. This played a role in winning the Battle of the Atlantic. The introduction of the jet engine, radar, early missiles, helicopters, post World War II, the development of military aviation was spurred by the Cold War stand-off between the super-powers. In the early 1960s, missiles were expected to replace manned interceptors, missiles were also expensive, especially against low-value ground targets. The 1970s saw the return of the fighter, and a greater emphasis on maneuverability. The 1980s through to the present day were characterized by stealth technology, airborne Early Warning provides advance warning of enemy activities to reduce the chance of being surprised. Many also have functions that allow them to direct or vector friendly fighters onto incoming bogeys. Bombers are capable of carrying payloads of bombs and may sacrifice speed or maneuverability to maximize payload. Experimental aircraft are designed to test advanced aerodynamic, structural, avionic and these are usually well instrumented, with performance data telemetered on radio-frequency data links to ground stations located at the test ranges where they are flown. Fighters establish and maintain air superiority, speed and maneuverability are usually requirements and they carry a variety of weapons, including machine guns and guided missiles, to do this. Forward Air Control directs close air support aircraft to ensure that the targets are nullified. Ground-attack aircraft support ground troops by weakening or nullifying enemy defenses, helicopter gunships and specialized ground attack aircraft attack enemy armor or troops and provide close air support for ground troops

Airliner
–
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines, although the definition of an airliner can vary from country to country, an airliner is typically defined as an aircraft intended for carrying multiple passengers or cargo in commercial service. The largest airliners are wide-body jets and these aircraft are frequently called twin-aisle aircraft because they generally have two separate aisles running from the front to the back of the passenger cabin. These aircraft are used for long-haul flights between airline hubs and major cities with many passengers. A smaller, more class of airliners is the narrow-body or single aisle aircraft. These smaller airliners are used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops and these airliners are the non-mainline counterparts to the larger aircraft operated by the major carriers, legacy carriers, and flag carriers and are used to feed traffic into the large airline hubs. These regional routes then form the spokes of an air transport model. The Beechcraft 1900, for example, has only 19 seats, when the Wright brothers made the world’s first sustained heavier-than-air flight, they laid the foundation for what would become a major transport industry. Their flight in 1903 was just 11 years before what is defined as the world’s first airliner. These airliners would have a significant impact on society, economics. If an airliner is defined as an aircraft intended for carrying passengers in commercial service. The Ilya Muromets was an aircraft with a separate passenger saloon, wicker chairs, bedroom, lounge. The aircraft also had heating and electrical lighting, the Ilya Muromets first flew on December 10,1913. On February 25,1914, it took off for its first demonstration flight with 16 passengers aboard, from June 21 – June 23, it made a round-trip from Saint Petersburg to Kiev in 14 hours and 38 minutes with one intermediate landing. However, it was never used as a commercial airliner due to the onset of World War I, in 1915 the very first airliner was used by Elliot Air Service. The aircraft was a Curtiss JN4, a biplane which was used mainly in World War I as a trainer. Later, it was used as a tour and familiarization flight aircraft in the early 1920s

General aviation
–
General aviation is the term for all civil aviation operations other than scheduled air services and non-scheduled air transport operations for remuneration or hire. General aviation flights range from gliders and powered parachutes to corporate business jet flights, the majority of the worlds air traffic falls into this category, and most of the worlds airports serve general aviation exclusively. General aviation covers a range of activities, both commercial and non-commercial, including flying clubs, flight training, agricultural aviation, light aircraft manufacturing. Of the 21,000 civil aircraft registered in the UK,96 per cent are engaged in GA operations, there are 28,000 Private Pilot Licence holders, and 10,000 certified glider pilots. Some of the 19,000 pilots who hold professional licences are also engaged in GA activities, GA operates from more than 1,800 airports and landing sites or aerodromes, ranging in size from large regional airports to farm strips. GA is regulated by the Civil Aviation Authority, although regulatory powers are being transferred to the European Aviation Safety Agency. The main focus is on standards of airworthiness and pilot licensing, general aviation is particularly popular in North America, with over 6,300 airports available for public use by pilots of general aviation aircraft. In comparison, scheduled flights operate from around 560 airports in the U. S, aircraft Owners and Pilots Association, general aviation provides more than one percent of the United States GDP, accounting for 1.3 million jobs in professional services and manufacturing. Most countries have authorities that oversee all civil aviation, including general aviation, Aviation accident rate statistics are necessarily estimates. In Canada, recreational flying accounted for 0.7 fatal accidents for every 1000 aircraft, while air taxi accounted for 1.1 fatal accidents for every 100,000 hours

Military aircraft
–
A military aircraft is any fixed-wing or rotary-wing aircraft that is operated by a legal or insurrectionary armed service of any type. Military aircraft can be either combat or non-combat, Combat aircraft are designed to destroy enemy equipment using their own aircraft ordnance, Combat aircraft are normally developed and procured only by military forces. Non-combat aircraft are not designed for combat as their primary function and these mainly operate in support roles, and may be developed by either military forces or civilian organizations. In 1783, when the first practical aircraft were established, they were adopted for military duties. The main role of fighters is destroying enemy aircraft in air-to-air combat, many are fast and highly maneuverable. Escorting bombers or other aircraft is also a common task and they are capable of carrying a variety of weapons, including machine guns, cannons, rockets and guided missiles. Many modern fighters can attack enemy fighters from a great distance, examples of air superiority fighters include the F-22 Raptor. World War II fighters include the British Spitfire, the American P-51 Mustang, an example of an interceptor would be the MiG-25. An example of a fighter is the Messerschmitt Bf 110. The term fighter is also applied to aircraft that have little air-to-air combat capability – for example the A-10 ground-attack aircraft is operated by USAF Fighter squadrons. Bombers are normally larger, heavier, and less maneuverable than fighter aircraft and they are capable of carrying large payloads of bombs, torpedoes or cruise missiles. Bombers are used almost exclusively for ground attacks and not fast or agile enough to take on enemy fighters head-to-head, a few have a single engine and require one pilot to operate and others have two or more engines and require crews of two or more. A limited number of bombers, such as the B-2 Spirit, have stealth capabilities that keep them from being detected by enemy radar, an example of a conventional modern bomber would be the B-52 Stratofortress. An example of a World War II bomber would be a B-17 Flying Fortress, bombers include light bombers, medium bombers, heavy bombers, dive bombers, and torpedo bombers. The U. S. Navy and Marines have traditionally referred to their light, attack aircraft can be used to provide support for friendly ground troops. Some are able to carry conventional or nuclear weapons far behind enemy lines to strike priority ground targets, attack helicopters attack enemy armor and provide close air support for ground troops. An example historical ground-attack aircraft is the Soviet Ilyushin Il-2 Shturmovik, several types of transport airplanes have been armed with sideways firing weapons as gunships for ground attack. These include the AC-47 and AC-130 aircraft, in modern air forces the distinction between bombers, fighter-bombers, and attack aircraft has become blurred
24.
Rotorcraft
–
A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor, the International Civil Aviation Organization defines a rotorcraft as supported in flight by the reactions of the air on one or more rotors. Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the flight, such as helicopters, cyclocopters, autogyros. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces, helicopters have several different configurations of one or more main rotors. A cyclocopter is a rotorcraft whose rotors are driven by the engine throughout the flight. At the present time flying model prototypes have been built in China, US, S. Korea, while similar to a helicopter rotor in appearance, the autogyros rotor must have air flowing up and through the rotor disk in order to generate rotation. Early autogyros resembled the fixed-wing aircraft of the day, with wings, late-model autogyros feature a rear-mounted engine and propeller in a pusher configuration. The autogyro was invented in 1920 by Juan de la Cierva, the autogyro with pusher propeller was first tested by Etienne Dormoy with his Buhl A-1 Autogyro. As power is increased to the propeller, less power is required by the rotor to provide forward thrust resulting in reduced pitch angles and rotor blade flapping. At cruise speeds with most or all of the thrust being provided by the propellers, a rotor kite or gyroglider is an unpowered rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly, a rotary wing is characterised by the number of blades. Typically this is two and six per driveshaft. A rotorcraft may have one or more rotors, various rotor configurations have been used, One rotor. Powered rotors require compensation for the reaction causing yaw, except in the case of tipjet drive. These typically rotate in opposite directions cancelling the torque reaction so that no tail rotor or other yaw stabiliser is needed and these rotors can be laid out as Tandem – One in front of the other. Coaxial – One rotor disc above the other, with drive shafts. An uncommon configuration, the 1948 Cierva Air Horse had three rotors as it was not believed a single rotor of sufficient strength could be built for its size. All three rotors turned in the direction and yaw compensation was provided by inclining each rotor axis to generate rotor thrust components that opposed torque

Aircraft maintenance
–
Aircraft maintenance is the overhaul, repair, inspection or modification of an aircraft or aircraft component. Maintenance may include such tasks as ensuring compliance with Airworthiness Directives or Service Bulletins, the maintenance of aircraft is highly regulated, in order to ensure safe and correct functioning during flight. National regulations are coordinated under international standards, maintained by such as the International Civil Aviation Organization. The maintenance tasks, personnel and inspections are all tightly regulated, the Maintenance, Repair, Overhaul Market was US$135.1 Billion in 2015, three quarters of the $180.3 B aircraft production market. Of this, 60% is for civil aviation, air transport 48%, business and general aviation 9%, rotorcraft 3%, and military aviation is 40%, fixed wing 27% and rotary 13%. Of the $64.3 Billion air transport MRO market, 40% is for engines, 22% for components, 17% for line, 14% for airframe and its is projected to grow at 4. 1% per annum till 2025 to $96B. Aircraft maintenance is highly regulated, because the smallest slip can lead to an aircraft crashing with consequent loss of life, the International Civil Aviation Organization sets global standards which are then implemented by national and regional bodies around the world. Each Contracting State is expected to use in its own regulations the one it prefers, thus, aircraft maintenance technicians, engineers and mechanics all perform essentially the same role. However different countries use terms in different ways to define their individual levels of qualification. Recognised licenses for aircraft maintenance personnel include, Aircraft Maintenance Engineer, Aircraft Maintenance Technician, in the USA also called an Aviation Maintenance Technician or colloquially Airframes and Powerplants. Aircraft maintenance personnel in Europe must comply with Acceptable Means of Compliance Part 66, Certifying Staff, AMC Part 66 is based on Joint Aviation Regulations promulgated by the Joint Aviation Authorities and on Air Transport Association Specification 104. Aircraft maintenance checks are inspections that have to be done on all commercial/civil aircraft after a certain amount of time or usage. In the case of an aircraft this may be an Aircraft Maintenance Engineer or Aircraft Maintenance Technician. Automated aircraft inspection systems have the potential to make aircraft maintenance safer, various solutions are currently developed, a collaborative mobile robot named Air-Cobot, and drones

Boeing
–
The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide. The company also provides leasing and product support services, Boeing stock is a component of the Dow Jones Industrial Average. The Boeing Companys corporate headquarters are located in Chicago and the company is led by President, Boeing is organized into five primary divisions, Boeing Commercial Airplanes, Boeing Defense, Space & Security, Engineering, Operations & Technology, Boeing Capital, and Boeing Shared Services Group. Boeing bought Heaths shipyard in Seattle on the Duwamish River, which became his first airplane factory. Boeing was incorporated in Seattle by William Boeing, on July 15,1916, Boeing was later incorporated in Delaware, the original Certificate of Incorporation was filed with the Secretary of State of Delaware on July 19,1934. Boeing, who studied at Yale University, worked initially in the timber industry and this knowledge proved invaluable in his subsequent design and assembly of airplanes. The company stayed in Seattle to take advantage of the supply of spruce wood. William Boeing founded his company a few months after the June 15 maiden flight of one of the two B&W seaplanes built with the assistance of George Conrad Westervelt, a U. S. Navy engineer. Boeing and Westervelt decided to build the B&W seaplane after having flown in a Curtiss aircraft, Boeing bought a Glenn Martin Flying Birdcage seaplane and was taught to fly by Glenn Martin himself. Boeing soon crashed the Birdcage and when Martin informed Boeing that replacement parts would not become available for months, Westervelt agreed to build a better airplane and soon produced the B&W Seaplane. This first Boeing airplane was assembled in a hangar located on the northeast shore of Seattles Lake Union. Many of Boeings early planes were seaplanes, on April 6,1917, the U. S. declared War on Germany and later in the year entered World War I. On May 9,1917, the became the Boeing Airplane Company. With the U. S. entering the war, Boeing knew that the U. S. Navy needed seaplanes for training, so Boeing shipped two new Model Cs to Pensacola, Florida, where the planes were flown for the Navy. The Navy liked the Model C and ordered 50 more, the company moved its operations to a larger former shipbuilding facility known as Boeing Plant 1, located on the lower Duwamish River, Washington state. Others, including Boeing, started selling other products, Boeing built dressers, counters, and furniture, along with flat-bottom boats called Sea Sleds. In 1919 the Boeing B-1, flying boat made its first flight and it accommodated one pilot and two passengers and some mail. Over the course of eight years, it made international airmail flights from Seattle to Victoria, on May 24,1920, the Boeing Model 8 made its first flight

The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations.

Airbus SAS is a division of the multinational Airbus Group SE that manufactures civil aircraft. It is based in Blagnac, France, a suburb of Toulouse, with production and manufacturing facilities mainly in France, Germany, Spain, China, United Kingdom, Airbus began as a consortium of aerospace manufacturers, Airbus Industrie. After a protracted sales process BAE sold its shareholding to EADS on 13 October 2006, Airbus has sixteen key sites in four countries, France, Germany, Spain and the United Kingdom. Final assembly production is based at Toulouse, France, Hamburg, Germany, Seville, Spain, Tianjin, China, Airbus has subsidiaries in the United States, Japan and India. The company produces and markets the first commercially viable digital fly-by-wire airliner, the Airbus A320, and the worlds largest passenger airliner, Airbus Industrie began as a consortium of European aviation firms formed to compete with American companies such as Boeing, McDonnell Douglas, and Lockheed. While many European aircraft were innovative, even the most successful had small production runs, in the mid-1960s, tentative negotiations commenced regarding a European collaborative approach. The same year Hawker Siddeley teamed with Breguet and Nord to study airbus designs, the Hawker Siddeley/Breguet/Nord groups HBN100 became the basis for the continuation of the project. By 1966 the partners were Sud Aviation, later Aérospatiale, Arbeitsgemeinschaft Airbus, later Deutsche Airbus, a request for funding was made to the three governments in October 1966. On 25 July 1967 the three agreed to proceed with the proposal. In the two years following this agreement, both the British and French governments expressed doubts about the project, the MoU had stated that 75 orders must be achieved by 31 July 1968. With concerns at proposal of the A300B proposal in December 1968, and fearing it would not recoup its investment due to lack of sales, West Germany took this opportunity to increase its share of the project to 50%. Given the participation by Hawker Siddeley up to point, France. Thus the British company was allowed to continue as a privileged subcontractor, Hawker Siddeley invested GB£35 million in tooling and, requiring more capital, received a GB£35 million loan from the West German government. Airbus Industrie was formally established as a Groupement dIntérêt Économique on 18 December 1970 and it had been formed by a government initiative between France, West Germany and the UK that originated in 1967. Its initial shareholders were the French company Aérospatiale and the West German company Deutsche Airbus, Aérospatiale and Deutsche Airbus each took a 36. 5% share of production work, Hawker Siddeley 20% and the Dutch company Fokker-VFW 7%. Each company would deliver its sections as fully equipped, ready-to-fly items, in October 1971 the Spanish company CASA acquired a 4. 2% share of Airbus Industrie, with Aérospatiale and Deutsche Airbus reducing their stakes to 47. 9%. In January 1979 British Aerospace, which had absorbed Hawker Siddeley in 1977, the majority shareholders reduced their shares to 37. 9%, while CASA retained its 4. 2%. The Airbus A300 was to be the first aircraft to be developed, manufactured and marketed by Airbus, by early 1967 the A300 label began to be applied to a proposed 320 seat, twin engined airliner

The diversification was partially to balance civilian business against any overreliance on military business, UTC became a mergers and acquisitions –focused organization, with various forced takeovers of unwilling smaller corporations. The next year, UTC forcibly acquired Otis Elevator, in 1979, Carrier Refrigeration and Mostek were acquired, the Carrier deal was forcible, while the Mostek deal was a white knight move against hostile takeover designs by Gould. Although M&A activity was not new to United Aircraft, the M&A activity of the 1970s and 1980s was higher-stakes, rather than aviation being the central theme of UTC businesses, high tech was the new theme. Some Wall Street watchers questioned the value of M&A at almost any price. Mostek was sold in 1985 to the French electronics company Thomson, UTC acquired Sundstrand Corporation in 1999, and merged it into UTCs Hamilton Standard unit to form Hamilton Sundstrand. In 2003, UTC entered the fire and security business by purchasing Chubb Security, in 2004, UTC acquired the Schweizer Aircraft Corporation which planned to operate as a wholly owned subsidiary under their Sikorsky Aircraft division.

GE Aviation, a subsidiary of General Electric, is headquartered in Evendale, Ohio, outside Cincinnati. GE Aviation is among the top aircraft engine suppliers, and offers engines for the majority of commercial aircraft, GE Aviation is part of the General Electric conglomerate, which is one of the worlds largest corporations. The division operated under the name of General Electric Aircraft Engines until September 2005, GE Aviations main competitors in the engine market are Rolls-Royce and Pratt & Whitney. GE operates two joint ventures with Snecma of France, CFM International and CFM Materials, General Electric had a long history in steam turbine work, dating back to the 1900s. In 1903 they hired Sanford Alexander Moss, who, in time and this led to a series of record-breaking flights over the next ten years. At first the role of flight was limited, but in the years immediately prior to WWII they became standard equipment on practically all military aircraft. This work made them the natural partner to develop jet engines when Frank Whittles W.1 engine was demonstrated to Hap Arnold in 1941. A production license was arranged in September, and several of the existing W.1 test engines shipped to the US for study, early jet engine work took place at GEs Syracuse, NY and Lynn, MA plants, but soon concentrated at the Lynn plants. On 31 July 1945 the Lynn plant became the Aircraft Gas Turbine Division, GE was repeatedly unable to deliver enough engines for Army and Navy demand, and production of the I-40 was also handed to Allison Engines in 1944. After the war ended, the Army canceled its orders for GE-built J33s and turned the production over to Allison. These changes in fortune led to debate within the company about carrying on in the engine market. However, the engineers at Lynn pressed ahead with development of a new engine, the TG-180, development funds were allotted in 1946 for a more powerful version of the same design, the TG-190. This engine finally emerged as the famed General Electric J47, which saw demand for several military aircraft. J47 production ran to 30,000 engines by the time the lines closed down in 1956, further development of the J47 by Patrick Clarke in 1957 led to the J73, and from there into the much more powerful J79. The J79 was GEs second hit, leading to a run of 17,000 in several different countries. The GE and Lockheed team that developed the J79 and the F-104 Mach 2 fighter aircraft received the 1958 Collier Trophy for outstanding achievement in aviation. Other successes followed, including the T58, and T64 turboshaft engines, J85, the TF39 was the first high-bypass turbofan engine to enter production. Entered into the C-5 Galaxy contest in 1964 against similar designs from Curtiss-Wright and Pratt & Whitney and this led to a civilian model, the CF6, which was offered for the Lockheed L-1011 and McDonnell Douglas DC-10 projects

More than 90% of Raytheons revenues were obtained from military contracts and, as of 2012, as of 2015, it is the third largest defense contractor in the United States by defense revenue. Raytheons headquarters moved from Lexington, Massachusetts, to Waltham, Massachusetts and its focus, which was originally on new refrigeration technology, soon shifted to electronics. The companys first product was a rectifier that was based on Charles Smiths earlier astronomical research of the star Zeta Puppis. The electron tube was christened with the name Raytheon and was used in a battery eliminator and this made it possible to convert household alternating current to direct current for radios and thus eliminate the need for expensive, short-lived batteries. In 1925, the changed its name to Raytheon Manufacturing Company and began marketing its rectifier, under the Raytheon brand name. In 1928 Raytheon merged with Q. R. S, Company, an American manufacturer of electron tubes and switches, to form the successor of the same name, Raytheon Manufacturing Company. In 1933 it diversified by acquiring Acme-Delta Company, a producer of transformers, power equipment, by the 1930s, it had already grown to become one of the worlds largest vacuum tube manufacturing companies. Within a few months of being awarded the contract, Raytheon had already begun to mass manufacture magnetron tubes for use in radar sets, at wars end in 1945 the company was responsible for about 80 percent of all magnetrons manufactured. During the war Raytheon also pioneered the production of radar systems. Raytheon ranked 71st among United States corporations in the value of World War II military production contracts, Raytheons research on the magnetron tube revealed the potential of microwaves to cook food. In 1945, Raytheons Percy Spencer invented the microwave oven by discovering that the magnetron could rapidly heat food, in 1947, the company demonstrated the Radarange microwave oven for commercial use.

Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world
