ABSTRACT:
Starters for gas turbine engines may be downsized or eliminated entirely by starting the turbine with a method including the steps of (a) combusting fuel in a combustion chamber for a limited period of time sufficient to provide combustion gas under pressure, (b) accelerating a turbine wheel 14 and a compressor 12 by expanding the gas from step (a) through the turbine wheel 14, (c) preventing the flow of combustion gas to the compressor by a valve 52 during the performance of steps (a) and (b), (d) following step (b) utilizing a portion of the kinetic energy of the accelerated turbine wheel 14 and compressor 12 to provide sufficient compressed air 88 to the combustion chamber 24 to scavenge and recharge the same and (e) repeating steps (a)-(d) inclusive until operation of the engine becomes self-sustaining.
