Aircraft oil-electricity hybrid energy supply system, aircraft and control method thereof

Abstract

The invention provides an aircraft oil-electricity hybrid energy supply system, an aircraft and a control method thereof. The energy supply system comprises an engine system, an engine controller, a power system and a fuel system; the engine system comprises an engine and a generator; the fuel system is connected with the engine through an oil way; the power output end of the engine is in drivingconnection with the generator; the generator is connected with the engine controller, and the engine controller is in control connection with the power system. Chemical energy generated in the fuel combustion process is converted into mechanical energy of the engine; the engine transmits mechanical energy to the generator to move, the generator converts the mechanical energy into electric energy,and the engine controller distributes the electric energy to the power system after rectifying the electric energy; compared with a pure electric aircraft, the cruising ability of the hybrid system ishigher, the engine does not directly drive the power system to work, and the aircraft is more stable and reliable in the flying process.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an aircraft fuel-electric hybrid energy supply system, an aircraft and a control method thereof. Background technique [0002] In recent years, with the development of automation technology, the types of aircraft are increasing. A stable and reliable power system is the basis for the normal operation of the aircraft. At present, aircraft widely use batteries or fuel oil as the source of working power. Restricted by their own performance shortcomings such as low battery energy density and low-temperature discharge capability, pure electric aircraft have a short flight time; another type is affected by the reliability of fuel engines and the environment. Affected by various factors, aircraft using fuel engines have operational reliability limitations. [0003] The inventor found in the research that the power system of the traditional aircraft has at least the following disadvantages: [...
