A rotary-wing aircraft, rotorwing aircraft or rotorcraft is a heavier-than-air aircraft with rotary wings that spin around a vertical mast to generate lift. The assembly of several rotor blades mounte

A Fairey Rotodyne prototype gyrodyne
On a helicopter, the main rotor or rotor system is the combination of several rotary wings with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter,
A Bell AH-1 SuperCobra with a 2-bladed semirigid main rotor
NOTAR helicopter with a rotorless tail
Tail Rotor of a Sea Lynx, the smaller tail rotor counteracts the torque of the spinning main rotor in many designs, although there are other solutions to this, such as having two counter-rotating main rotors
Looking up at CH-53G, which has 6-blades on its main rotor
