ABSTRACT:
A gas turbine engine fuel control system has a three-dimensional cam which is positioned by sensed values of engine compressor inlet and outlet pressures. The cam has two profiles which respectively indicate a desired ratio of the compressor pressures and a desired fuel flow. Interlinked cam followers engage the respective cam profiles and are also responsive to a device for setting a desired engine thrust. The cam follower linkage positions a variable metering device for the engine fuel supply.
