Safran Aircraft Engines (previously Snecma) is a French aerospace engine manufacturer headquartered in Courcouronnes, France. It is among the top suppliers in the industry, with end-to-end expertise from design to production of high-performance aircraft engines for commercial and military aircraft as well as rocket engines for launch vehicles and satellites. It also offers a complete range of engine support services to airlines, armed forces and other operators.

Some of its notable past developments, alone or in partnership, include the M88 for the Rafale, Olympus 593 for the Concorde, CFM56/CFM-LEAP for single-aisle airliners, and the Vulcain engines for the Ariane 5.

It has 15,700 employees working at 35 production sites, offices, and MRO facilities worldwide, it plows a significant portion of its sales back into research and development, filing an average of nearly 500 patents each year.

Safran Aircraft Engines is a subsidiary of Safran.

History[edit]

  • 1945: Snecma was formed when the French aircraft engine manufacturer Gnome & Rhône was nationalised. The name 'Snecma' was an acronym for Société nationale d'études et de construction de moteurs d'aviation (in English: 'National Society of Research and Construction of Aviation Engines').
  • 1961: Snecma and Bristol Siddeley formed a joint venture to produce a high-performance jet engine for the Concorde. The main body of the engine came from the Bristol Olympus, which was further improved with several refinements including the addition of the variable intakes necessary for supersonic flight.
  • 1970: Messier and Snecma agreed to merge their landing gear business. The following year, Messier-Hispano was formed, which was fully acquired by Snecma in 1973. Snecma's landing gear business was further consolidated by the creation of Messier-Hispano-Bugatti (later renamed Messier-Bugatti) in 1977.
  • 1994: Messier-Dowty was formed following the merger of the landing gear businesses of Snecma (Messier) and the British TI Group (Dowty).
  • 1998: Snecma took full control of Messier-Dowty.
  • 1999: Snecma Services was created to consolidate all maintenance, repair and overhaul (MRO) operations (including Sochata-Snecma).
  • 2000: Snecma acquired Labinal, along with its Turbomeca and Microturbo subsidiaries.
  • 2001: Hurel-Hispano (now renamed and known as Safran Nacelles) was created to consolidate the group's engine nacelle and thrust reverser business.
  • 2005: Snecma merged with Sagem to form Safran. Snecma was divided into two divisions of the new group (propulsion and equipment).
  • 2010: Snecma and GE formed CFM Materials as a 50/50 joint venture.
  • 2016: Snecma was renamed Safran Aircraft Engines as the main subsidiary of Safran.

Research[edit]

open rotor concept

The European Commission launched in 2008 an open rotor demonstration led by Safran within the Clean Sky program with 65 million euros funding over eight years : a demonstrator was assembled in 2015, and ground tested in May 2017 on its open-air test rig in Istres, aiming to reduce fuel consumption and associated CO2 emissions by 30% compared with current CFM56 turbofans.[2] With its 30:1 bypass ratio, it should deliver a 15% improvement over the CFM LEAP already at 11:1; but Airbus is more interested in the more conventional Ultra High Bypass Ratio (UHBR) turbofan at 15:1, which could be introduced from 2025, offering 5% to 10% better efficiency than the LEAP and to be tested from 2020.[3]

Products[edit]

The company's major commercial aircraft engine is the CFM International CFM56. Produced by a partnership between Safran Aircraft Engines and General Electric, CFM56s power more than 4,900 aircraft around the world.

Safran Aircraft Engines is also the main partner for the General Electric CF6-80 and GE90 programs, it is also involved in the high-thrust turbofan business as part of the Engine Alliance GP7000 program, which produces one of the only two engines certified to power the Airbus A380.

Through the PowerJet partnership with NPO Saturn of Russia, Safran Aircraft Engines also produces SaM146 engines for the Sukhoi Superjet 100.
