Driving mechanism and driving method of hybrid power helicopter

Abstract

The invention discloses a driving mechanism of a hybrid power helicopter. The driving mechanism of the hybrid power helicopter comprises a fuel tank, an engine, a clutch, a first locker, a planetary gear mechanism, an energy storage device, a generator / electric motor, a second locker, a second generator / electric motor, a torque coupler, a tail end gear box, a tail rotor subsystem, an swashplate and a rotor wing subsystem, wherein the clutch and the first locker are mounted between the engine and the planetary gear mechanism, and the second locker is mounted between the generator / electric motor and the planetary gear mechanism. Two power sources comprising a basic power source and an auxiliary power source are utilized, the two power sources are reasonably matched and selected when driving the helicopter, accordingly, the problems that the power source of a conventional helicopter is single, a drive system is complicated, a drive device is heavy, mechanical failure easily happens and the like are solved, and the safety and the maneuverability of the helicopter are improved.

Description

technical field [0001] The invention belongs to the field of aviation aircraft, and specifically relates to a drive mechanism of a hybrid power helicopter. technical background [0002] Helicopter is an aircraft that provides upward lift and propulsion by one or more horizontally rotating rotors. Its outstanding feature is that it can do low-altitude, low-speed and maneuvering flight with the same direction of the nose, which makes the helicopter have a wide range of uses. In terms of military use, it can be used for ground attack, logistics support, battlefield rescue, reconnaissance and patrol, electronic countermeasures, etc.; in civilian use, it can be used for medical rescue, short-distance transportation, emergency rescue, aerial photography, etc. [0003] However, at present, traditional helicopters use dual engines. Although dual engines are used to improve flight reliability, it brings low flight speed, short mileage, large mechanical vibration, heavy maintenance an...

AI Technical Summary

Problems solved by technology

[0003] However, at present, traditional helicopters use dual engines. Although dual engines are used to improve flight reliability, it brings low flight speed, short mileage, large mechanical vibration, heavy maintenance and repair workload, complex transmission system, and heavy weight of the transmission device. , Mechanical failure is prone to occur, and it is also vulnerable to ground attacks, and the flight safety needs to be improved
