Helicopters - History Documentary Films Helicopter - a sort of rotorcraft where lift and thrust are provided by rotors. This enables the helicopter to take off and land vertically, to float, and to fly ahead, backward, as well as laterally. These attributes permit helicopters to be utilized in congested or isolated locations where fixed-wing aircraft as well as several types of VTOL (vertical launch and also landing) plane can not do. Words helicopter is adapted from the French language, created by Gustave Ponton in 1861, which originates from the Greek helix "helix, spiral, whirl, convolution" and pteron "wing". English-language labels for helicopter include "chopper", "copter", "helo", "heli", as well as "whirlybird". Helicopters were created and built throughout the first half-century of air travel, with the Focke-Wulf Fw 61 being the very first operational helicopter in 1936. Some helicopters got to limited production, however it was not until 1942 that a helicopter made by Igor Sikorsky reached full-blown manufacturing, with 131 plane developed. Though the majority of earlier styles used more than one primary rotor, it is the single primary rotor with anti-torque tail rotor setup that has become the most typical helicopter configuration. Tandem rotor helicopters are additionally in prevalent usage due to their better payload ability. Coaxial helicopters, tiltrotor plane, as well as substance helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, and other sorts of multicopter have been created for specialized applications such as unmanned drones.
