Development of flow metering for electric aircraft oil pump

In order to solve the difficulty of flow control in electric aircraft oil pump system, an electric aircraft oil pump was used as research object, with speed range of 2000rpm∼9000rpm, temperature range of 270K∼325K, pressure between the input and output of pump do not exceed 0.6MPa, and aviation 8B aircraft oil as medium. The influencing factors of aircraft oil flow were analysed, and an experimental system for researching flow metering methods was constructed. Based on the experimental data, an accurate flow metering model was established, which is significant for the metering and control of electric aircraft oil pump systems.
