  • Fuel supply control system for a turbine engine
    Patent number: 4380894
    Abstract: A fuel supply control system is disclosed having a means for determining an engine load condition based on the revolution speed of a compressor shaft and a means for determining a target speed of a turbine output shaft. The latter means increases the target speed in a relatively low engine load condition to increase an inertia moment applied to the turbine output shaft and thereby to maintain the output shaft revolution speed within a given range, even when the load applied to the engine is rapidly increased.
