FIELD: aircraft engineering.
SUBSTANCE: invention relates to aircraft engineering, particularly, to vertical take-off and landing of an aircraft. Aircraft consists of engine, pushing lifting screws, screw drive system, control system, cabin and housing, torque source and units transmitting torque from torque source to pushing lifting screws. Aircraft is used to drive and control rotation speed and inclination of pushing rotors and to control rotation speed of lead screw hydromechanical system, which comprises four hydromechanical gearboxes (HMGB), hydraulic motors, a power take-off box, a working fluid tank, hydraulic pumps, a control unit of the electromechanical hydraulic distributor of the HMGB gearshift, hydromechanical motion control units.
EFFECT: reduced weight, possibility of landing and takeoff from small sites.
