FIELD: aviation technology.
SUBSTANCE: aircraft is comprised of a body, a main rotor located above the body, and at least two rotary propellers located below the main screw. The main rotor is made autorotating with the possibility of forced spin-up at low speeds of level flight, during take-off, landing and/or hovering. Rotary propellers are located on rotary supports with the ability to smoothly change the angle between the direction of thrust and the vertical. The main rotor is made with the possibility of changing the pitch, while its diameter is selected in such a way as to provide a load per unit swept disk more than 20 kg/m2. The pivot screws are configured to provide the necessary lifting force for the take-off of the aircraft.
EFFECT: invention an aircraft design that combines the advantages of a multicopter and a gyroplane.
