Multi-engine autothrottle providing automatic engine EPR equalization

摘要

A throttle controller for a vehicle, such as an aircraft, having a plurality of engines (36-42). Each engine is regulated by a throttle. The controller includes a thrust sensor (44), a speed sensor (IAS), and an actuator (10). The thrust sensor (44) responds to the engines (36-42) to produce a plurality of thrust signals (22). These thrust signals correspond to the thrust produced by a different corresponding one of the engines. The speed sensor (IAS) can produce a speed signal corresponding to aircraft speed. The actuator (10) can adjust the throttle of each engine. The actuator is connected to the speed (IAS) and thrust sensors (44) and can respond to their signals to adjust each throttle and balance the thrust of the engines.
