He built a quadrocopter and calculated the trajectory of flight to the moon: 133 years since the birth of George Botezat

    On June 7, 1882, Georgy Aleksandrovich Botezat was born. For 57 years of his life, he built the world's first four-rotor helicopter, calculated the flight path to the moon, which was used to develop the Apollo program, and wrote several works on mechanics, aircraft construction and the operation of a rotor blade.

    Georgy Botezat was an electrical engineer by training, he graduated from institutes in Kharkov and Belgium (Belgium). One of his main inventions is a helicopter with several screws. A four-screw circuit simplified the control, turning the device by changing the position of the bow blades.

    Funds for the creation of a helicopter were given to the inventor by the US Army. The task of Botezat was to make an aircraft with vertical take-off and landing. The $ 200,000 issued was not enough for prototypes, so Botezat immediately built a full-size device.

    The device first flew in 1922. In one of the experimental flights, he lifted a cargo weighing 450 kg to a height of 4 meters. In 1922 and 1923, this first U.S. Air Force helicopter made 100 flights.

    Technical characteristics of the first quadrocopter :
    Control: 1 pilot
    Payload: up to four passengers
    Dimensions length / width / height: 20 x 20 x 3 meters
    Weight: 1633 kg
    Engine:1 Le Rhone rotary engine with 180 horsepower
    maximum speed: 48 km / h
    Working height: 5 m
    Maximum height: 9.1 m

    The US government has stopped funding the Botesat project, preferring gyros. The inventor in 1926 founded a company for the production of fans and began to supply them for installation in industrial and residential buildings and the US Navy - for new cruisers.

    In 1938, George Botezat with pilot Boris Sergievsky founded Helicopter Corp. of America. The company's first helicopter was the GB-2. A modified version of the device called GB-5 was the last of the inventor's helicopters. The helicopter could not rise above one and a half meters and crashed on one of the tests.

    George Botezat died in 1940 at the age of 57 years.
