ABSTRACT:
A load sharing apparatus and method for coupled master and slave engines having respective throttle actuators to receive initial throttle signals, and load transmitters for transmitting load signals reflecting load on the particular engine. Apparatus has a load comparison structure which receives load signals from the load transmitters of the engines and produces a differential signal reflecting comparison of the engine loads. The apparatus also includes a servo structure which receives the differential signal and produces an output signal which is a servo signal. The servo signal is transferred to the throttle actuator of the slave engine, to change the initial throttle signal to the slave engine by an amount dependent on the servo signal thus sharing loads equally between the master and slave engines.
