Igor Sikorsky: Meaning (information, definition, explanation, facts)

Igor Ivanovich Sikorsky (May 25, 1889 - October 26, 1972) was a Russian-born pioneer of aviation who designed the first four-engine aeroplanes and the first modern helicopter.

Igor Sikorsky was born in Kiev, and studied at the Naval War College in St. Petersburg. His early work included the construction, as chief engineer, of the first four-motor aircraft; he acted as the test pilot for its inaugural flight, on May 13, 1913. Sikorsky's planes were used by the Russian government as bombers in World War I.

Sikorsky emigrated from Russia to the United States in 1919, at the age of 30, fleeing the Bolshevik regime installed after the October Revolution.

In 1923 he formed the Sikorsky Aero Engineering Company, which was purchased by and became a subsidiary of United Aircraft (itself now a part of United Technologies Corporation. The company manufactured flying boats such as the Sikorsky S42, used by Pan Am for trans-atlantic flights and known as Pan Am Clippers.

Sikorsky had experimented with helicopter type flying machines whilst in Russia; he brought his work to fruition on the 24th May 1940 when he performed the first successful helicopter flight, in the Vought-Sikorsky 300, a machine with a single three-blade rotor powered by a 75 horsepower (56 kW) engine.

The Sikorsky Aircraft Corporation continues to the present day, as one of the world's leading helicopter manufacturers.
