A helicopter is a kind of rotorcraft in which elevate and thrust are furnished by using horizontally spinning rotors. This lets in the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes enable helicopters to be used in congested or remoted areas the place fixed-wing plane and many types of VTOL (Vertical Takeoff and Landing) plane can't perform.Helicopters had been developed and constructed during the first half-century of flight, with the Focke-Wulf Few sixty-one being the first operational helicopter in 1936.
Some helicopters reached confined production; however, it was once now not till 1942 that a helicopter designed via Igor Sikorsky reached full-scale production, with 131 planes built.Although most beforehand designs used extra than one important rotors, the configuration of a single foremost rotor (monocopter) accompanied by way of a vertical anti-torque tail rotor has come to be the most frequent helicopter configuration. Twin-main rotor helicopters (bicopters), in both tandem and transverse rotors configurations, are additionally in use due to their higher payload ability than the monorotor design. Coaxial-rotor helicopters, tiltrotor aircraft, and compound helicopters are all flying today. Quadrotor helicopters (quadcopters) have been pioneered as early as 1907 in France, and different kinds of multicopters have been developed for specialized functions such as drones.
