FIELD: aeronautical engineering; heavier-than-air flying vehicles.
SUBSTANCE: proposed aircraft includes fuselage, wings, power plant with several engines, tail unit, tractor propeller and main rotors. Each main rotor is connected with two engines. Aircraft is provided with four wings with engine mounted on each wing. Two wings are located in nose fuselage and two other wings are located in rear fuselage. Main rotors are located between wings in nose fuselage and rear fuselage. Main rotor are closed with flaps against incoming air flow. Part of air flow formed during operation of main rotors is directed through passages in wings.
EFFECT: enhanced safety of flight.
