History of Helicopters – Helicopter Invention Documentary Film

A helicopter is a type of rotorcraft where lift and thrust are provided by blades. This allows the helicopter to take off and land up and down, to hover, and to fly forward, in reverse, and laterally. These attributes allow helicopters to be made use of in overloaded or isolated locations where fixed-wing plane and many kinds of VTOL (upright takeoff and landing) plane can not do.

The word helicopter is adjusted from the French language helicoptere, created by Gustave Ponton d’Amecourt in 1861, which stems from the Greek helix „helix, spiral, try, convolution“ and pteron „wing“. English-language nicknames for helicopter include „chopper“, „copter“, „helo“, „heli“, and „whirlybird“.

Some helicopters got to limited manufacturing, but it was not until 1942 that a helicopter created by Igor Sikorsky reached full-blown production, with 131 airplane developed.
