FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering and my be used in designs of light convertiplanes and drone rotorcraft. Proposed drone rotorcraft represents a monoplane with front horizontal fins including two-fin empennage mounted at outer wing nacelles, short fuselage, engine to transmit torque via transmission to push-and-pull propellers to create horizontal and vertical thrust. Proposed drone represents a twin-fuselage plane with tandem rotors in 1+2 configuration. Rotary plane of the front large rotor is located between fuselage and confined inner boards, rear and front edges. Transmission system comprises tail reduction gears of two smaller rotors and central T-like main reduction gear.
EFFECT: higher efficiency, better takeoff and landing characteristics.
