Définition(s)

  • Helicopters are the most common type of rotary-wing aircraft, which generate lift through the revolution of wings (rotor blades) around a mast. In the case of helicopters, these rotors are driven by one or more engines throughout the flight, and the rotors also provide multidirectional thrust.
