Development of flow metering for electric aircraft oil pump

“…With the continuous advancement of multi-electric aero-engine technology and the application of advanced technologies such as distributed and intelligent control, electric-driven aircraft oil pumps have become an important direction for the research of aircraft oil systems [2][3]. The electric aircraft oil pump is composed of a motor, a fuel pump and a controller [4], according to the aircraft oil flow demand of the FADEC，it adjusts the motor speed to achieve the goal of precise flow control. It is a pure digital adjustment system ,compared with the traditional mechanical hydraulic aircraft oil system, the advantages [5] of the electric aircraft oil pump are as follows: (1) the structure is simplified, the power source of the aircraft oil pump is electric energy, and there is no need for complicated mechanical transmission such as the engine accessory gearbox; (2) the cost is lower, the driving part of the electric aircraft oil pump includes a motor and a driver, and the development, production and maintenance costs are lower than those of a mechanical transmission system.…”
