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...
[ What we claim is:] [1.] In a gas turbine engine comprising:a combustor chamber,a compressor, mounted on a rotatable shaft, for supplying compressed gas to said combustion chamber,a supply of fuel,a controller for provision of said fuel to said combustion chamber,driving means for permitting the rotation of said shaft to supply power to said controller when combustion of fuel within said combustion chamber is self sustaining, andhydraulic means for starting rotation of said shaft, including a source of hydraulic fluid and a first hydraulic motor driven ...
