Plug-in hybrid power driving device for tilt-rotor aircraft

Abstract

The invention discloses a plug-in hybrid power driving device for a tilt-rotor aircraft. The plug-in hybrid power driving device comprises an engine, a motor / generator, a traction motor, a power distribution device, a wing nacelle, a power coupling device, an energy storage device, a motor / generator controller, a motor controller and parts such as a clutch and a brake. According to a hybrid power driving assembly, the device comprises a plurality of power sources so that power combination can be carried out according to the flight state of the aircraft: the left and right rotors can be driven by the traction motor, and combined driving of the rotors can be realized by the motor and the engine so as to enable the engine to run in an optimum fuel using efficiency area. According to the device, the mechanical structure of a transmission system is simplified so that the transmission efficiency is increased; and meanwhile, when the traction motor is under the conditions of electricity shortage and fault, the engine can be started in time to supplement electricity and power, so that the reliability of the system is increased.

Description

technical field [0001] The invention belongs to the technical field of hybrid power drive, and more specifically relates to a hybrid power drive device for a tilt rotor aircraft. technical background [0002] The traditional power drive device used for tilt-rotor aircraft usually uses a pure engine as the power source, cooperates with a gearbox, a multi-stage transmission shaft and an actuator, and finally drives the rotor to rotate. This driving method has a single power source and low transmission efficiency. , The mechanical structure is complicated, which reduces its reliability, especially in the case of engine failure, the safety factor of the aircraft is extremely low; at the same time, the output power of the traditional drive device cannot be adjusted with the flight conditions of the tilt rotor aircraft, and the engine cannot work at The best fuel economy zone increases the fuel consumption and reduces the flight time of the aircraft. Therefore, the present invent...
