Abstract

The invention, which relates to the technical field of unmanned aerial vehicles, discloses a large freight transport unmanned aerial vehicle fuel system. A first oil supply system comprises a first oil tank, a fuel tank selection electromagnetic valve, a fuel main switch, a fuel filter, an electric booster oil pump, a second one-way valve, an oil pressure sensor, an oil pressure regulator, an oilreturn guide pipe and an oil return tank, and is formed by combining an oil supply guide pipe and a three-way joint. A second oil supply system comprises a second oil tank, a fuel tank selection electromagnetic valve, a fuel main switch, a fuel filter, a mechanical booster oil pump, a first one-way valve, an oil pressure sensor, an oil pressure regulator, an oil return guide pipe and an oil returntank, and is formed by combining an oil supply guide pipe and a three-way joint. According to the technical scheme, the oil supply pressure can be actively adjusted, a redundant backup oil supply andtransportation system is provided, the design is reasonable, the service life is long, the safety performance is excellent, and the working requirement of the electronic injection type aviation piston engine is met.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a large-scale cargo unmanned aerial vehicle fuel system and a control method thereof. Background technique [0002] At present, the UAV fuel system is mainly used to store the fuel required for flight, and continuously supply fuel to the engine during the flight of the UAV to ensure the safe and reliable continuous operation of the engine and provide power for the UAV. The aviation piston engines generally used by UAVs use mechanical carburetors to control and adjust the fuel supply of the engines. The carburetor-supplied aviation piston engines have simple requirements for the UAV fuel system and have no special requirements for the fuel supply pressure. Its fuel system usually consists of a fuel tank, an oil supply pipeline and a ventilation pipeline. [0003] With the continuous increase of drone flight time, the aviation piston engine used in it is changed t...
