SYSTEM OF STEERING GEARS OF THE TRANSPORT AIRCRAFT Russian patent published in 2018 - IPC B64D41/00 F16D21/02 

FIELD: aircraft.

SUBSTANCE: invention relates to the equipment of aircraft and is intended for constructing a flight control system and for realizing the power supply of the aircraft's actuators in normal and emergency flight conditions. System of the steering gear of the transport aircraft consists of the main AC generators whose rotors are connected to the rotors of the propulsion engines, auxiliary electric generators of alternating current, the rotors of which are connected to the rotors of the auxiliary power plant (APU) and the turbine unit, respectively, of the storage batteries, current converters, electromechanical steering gear (EMSG). In the regular flight mode, wing steering surfaces and high-lift devices are deflected by electromechanical steering gears (EMSG). To deflect the right and left sections of the elevating rudder, along with electrohydraulic steering gears (EHSG) dual-mode hydraulic steering gears (DHSG) are used, which normally operate from hydraulic pumping stations with alternating current electric motors, and when failures are switched to power supply from the aircraft's electrical systems. Rudder is deflected by means of two electrohydraulic steering gears (EHSG), which work in conjunction with hydrostatic steering gears (HSSG).

EFFECT: technical result consists in reducing the weight of the equipped aircraft, reducing the total number of complex elements of hydraulic and pneumatic systems, simplifying the maintenance of the aircraft.
