一种飞机液压直流电动泵控制系统及方法
By integrating a controller, electric pump control switch, and hydraulic computer into a system that combines ground speed, engine speed, and flap position signals, automatic control of the aircraft's hydraulic electric pump is achieved. This solves the problem of traditional control relying on manual operation by the pilot and reduces the pilot's workload.
