Abstract

A parallel connection general aircraft pneumoelectric hybrid power system, including an internal combustion engine, a continuously variable transmission device, a centrifugal clutcher, a storage battery, a motor, a decelerator, an LNG storage tank and an LNG carburetor; a power output shaft of the internal combustion engine is connected with the continuously variable transmission device, an inner disc of the clutcher is fixedly provided on the output shaft of the continuously variable transmission device in a sleeving mode, an outer disc of the clutcher is fixedly provided with an outer gear ring in a sleeved mode, an input shaft of the decelerator is fixedly provided with a first gear in a sleeved mode, the first gear meshes with the outer gear ring; the storage battery is connected with a power supply port of the motor, a main shaft of the motor is covered in a sleeving mode with a second gear, the second gear meshes with the outer gear ring; the second gear relative to the main shaft of the motor only has linear freedom of movement, a fuel inlet of the internal combustion engine is connected with a fuel outlet of the LNG storage tank through the LNG carburetor; a fuel supply assembly is arranged between the internal combustion engine and the LNG carburetor, the LNG storage tank is assembled with a storage tank self pressurization assembly. The hybrid power system adopts the internal combustion engine using liquified natural gas as fuel, the method lowers the pollution to environment, and guarantees the endurance capacity of aircraft.

Description

technical field [0001] The invention belongs to the technical field of general aircraft power systems, in particular to a parallel gas-electric hybrid power system for general aircraft. Background technique [0002] General-purpose aircraft refers to the general term for aircraft engaged in other civil aviation activities other than public air transport aircraft such as scheduled passenger and cargo, and general-purpose aircraft power system refers to the general term for aircraft engines and accessories necessary to ensure the normal operation of the engines. At present, the engines used in general-purpose aircraft include piston aeroengines, rotary aeroengines, electric engines, and oil-electric hybrid engines. [0003] The number of general-purpose aircraft using piston aeroengines and rotary aeroengines is the largest, and the above two engines mainly use petroleum-based fuels such as gasoline or aviation kerosene as energy sources, but the environmental pollution of pet...

AI Technical Summary

Problems solved by technology

[0005] In order to reduce environmental pollution while ensuring endurance, the number of general-purpose aircraft using gasoline-electric hybrid engines is gradually increasing. The coordinated work of fuel-type internal combustion engines and electric engines can provide the aircraft with the required energy, which can indeed alleviate the problem to a certain extent. Compared with purely using electric engines, the endurance of general-purpose aircraft has also been improved. However, because fuel-type internal combustion engines still need to consume petroleum-based fuel, the problem of environmental pollution has not been fundamentally resolved.
