ABSTRACT:
Gas turbine engine powerplant has an engine 10 including a fuel pump 14 driven by the engine to supply fuel to the combustor 12 thereof. The pump flow rate varies in accordance with the requirements of the engine as determined by an electric control system 17. Power supply for the control system is derived from an alternator 29 driven by a hydraulic motor 28 fed by pump delivery. A constant flow device 22 arranged between the pump and the motor ensures constant speed for the alternator and thus a constant voltage for the control system.
