FIELD: aircraft engineering.
SUBSTANCE: invention relates aircraft engineering, particularly to system of rotors drive system. Proposed system comprises the system of rotors, main reduction gearbox to drive said rotors, overrunning clutch and system of forward thrust. Note here that said forward thrust system is driven by the main reduction gearbox, while overrunning clutch is thrown into mesh with the latter so that torque developed by the system of rotors in autorotation is absorbed by the forward thrust system during high-speed flight when rotor autorotates, thus, bringing about rotor lift.
EFFECT: improved control over RPM developed by rotor system and reduced vibration.
