History of Helicopters - Helicopter Invention Documentary Film

A helicopter is a type of rotorcraft where lift and drive are provided by rotors. This allows the helicopter to remove and land vertically, to float, and to fly forward, backward, and laterally. These attributes permit helicopters to be utilized in stuffed or isolated locations where fixed-wing airplane and many types of VTOL (vertical takeoff and landing) airplane can not do.

Words helicopter is adjusted from the French language hélicoptère, coined by Gustave Ponton d'Amecourt in 1861, which originates from the Greek helix "helix, spiral, try, convolution" and pteron "wing". English-language labels for helicopter include "chopper", "helicopter", "helo", "heli", and "whirlybird".

Some helicopters got to minimal production, however it was not till 1942 that a helicopter made by Igor Sikorsky got to full-blown manufacturing, with 131 airplane built. Most earlier designs utilized more than one major rotor, it is the single major blades with anti-torque tail rotor configuration that has come to be the most common helicopter configuration. Coaxial helicopters, tiltrotor plane, and compound helicopters are all flying today.

The earliest referrals for upright flight have come from China. Since around 400 BC, Chinese youngsters have had fun with bamboo flying toys. This bamboo-copter is spun by rolling a stick affixed to a rotor. The spinning develops lift, and the toy flies when released. The 4th-century AD Daoist publication Baopuzi by Ge Hong reportedly explains a few of the concepts integral to rotating wing airplane.

This Chinese helicopter toy was introduced into Europe and showed up in Renaissance paints and other works. Early Western scientists created flying machines based upon the initial Chinese model.
