    • 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 of supplying power back to the engine core. This, coupled with the bleed air that is diverted from the high pressure turbine and the low pressure turbine, allows the high pressure spool and the low pressure spool to run at lower speeds when high engine thrust is not needed or desired, but when the at least one engine accessory is still needed.
    • 气动涡轮机驱动系统耦合到包括低压和高压压缩机,低压和高压涡轮机,锁止离合器和由高压压缩机驱动的至少一个发动机附件的燃气涡轮发动机。 气动驱动的涡轮驱动系统选择性地将从高压压缩机排出的空气排出并将其提供到联接到至少一个发动机附件的空气涡轮机。 因此,系统选择性地降低从高压压缩机提取的功率,并且能够将功率返回到发动机芯。 这与从高压涡轮机和低压涡轮机转向的排出空气相结合,允许高压阀芯和低压阀芯在不需要或期望的高发动机推力时以较低的速度运行,但是当at 仍然需要至少一个发动机附件。
