초록

A hydraulic start system is provided having separate, sequentially started hydraulic motors for the controller PMG and for the gas turbine engine starter. Fluid pressure is provided by a hydraulic accumulator to both motors through separating valves. The PMG motor is supplied with fluid first and that drives the PMG to power up and initialize the controller before the starter motor is utilized. The engine itself is coupled to both the starter motor and the PMG through overrunning clutches such that starting the PMG does not start the engine. Once the con...
