Helicopter

A helicopter is an air craft designed to lift off the ground directly without a runway. It is propelled by one or more horizontal engines. Helicopters are different as compared to conventional fixed-wing aircrafts; they are classified as rotary-wing aircrafts. The term helicopter is derived from the Greek words 'helix,' which means spiral and 'petron' meaning wing.

The first fully functional helicopter was made in the year 1901, by Jan Bahyl. It was 6.5 meters long, weighed 50 kgs and flew nearly 50 cm above the ground. On May 5, 1905, Bahyl flew his helicopter at a height of 4 m above the ground for over 1500 m. This event was documented by the International Airship Organizement Corpis. The year 1936 saw Heinrich Focke, build the Focke-Wulf Fw 61, which was the first fully-controllable helicopter of its kind. The first helicopter with a single-rotor engine was made by Igor Sikorsky, in 1939. The helicopter is renowned for its maneuverability and they can hover in place, reverse, and the most striking feature is its ability to take off and land vertically at almost any location.
