A pneumatically driven turbine drive system is coupled to a gas turbine engine that includes low and high pressure compressors, low and high pressure turbines, a lock-up clutch, and at least one engine accessory driven by the high pressure compressor. The pneumatically driven turbine drive system selectively bleeds air discharged from the high pressure compressor and supplies it to an air turbine that is coupled to the at least one engine accessory. Thus, the system selectively reduces the power extracted from the high pressure compressor and is capable ...
1. A gas turbine engine including a turbine drive system, comprising: an engine case;a low pressure compressor, a high pressure compressor, a high pressure turbine and a low pressure turbine disposed in flow series within the engine case, the high pressure compressor and the high pressure turbine mounted on a high pressure spool and the low pressure compressor and the low pressure turbine mounted on a low pressure spool, each spool rotationally mounted within the engine case and configured to rotate at a speed;at least one engine accessory having an inpu...
