    Abstract: A gas turbine engine includes a compressor section and a combustion section with a scroll, a scroll baffle, a combustor, and a combustor case. The scroll defines an interior scroll flow path. The scroll baffle surrounds the scroll to define a scroll cooling passage. The combustor case surrounds the combustor and the scroll baffle to define a collector space. Moreover, the engine includes a turbine section with a turbine rotor and a turbine rotor blade shroud that includes a shroud cooling passage. The compressor flow path is fluidly connected to the scroll for cooling the scroll. Also, the scroll cooling passage is fluidly connected to the shroud cooling passage for cooling the turbine rotor blade shroud. Furthermore, the shroud cooling passage is fluidly connected to the collector space. Flow from the collector space flows into the combustor, along the interior scroll flow path, toward the turbine rotor.

    Abstract: Auxiliary power units and methods and systems for activation and deactivation of a load compressor therein are provided. Auxiliary power unit includes the load compressor having an impeller, APU engine, coupling member, pre-spinning means, and APU controller. APU engine is adapted to be mechanically engaged to load compressor to drive load compressor to provide pneumatic power and to be disengaged when the need for pneumatic power ceases. Coupling member couples load compressor and APU engine and is configured to be controllably moved between an engaged position in which the APU engine is mechanically engaged with the load compressor, and a disengaged position, in which the APU engine is disengaged from the load compressor. APU controller is operably coupled to load compressor, APU engine, coupling member, and pre-spinning means and adapted to receive and be responsive to rotational speed signals for controlling movement of coupling member between engaged and disengaged positions.

    Abstract translation: 提供了用于在其中启动和停用负载压缩机的辅助动力装置和方法和系统。 辅助动力单元包括具有叶轮，APU发动机，联接构件，预纺装置和APU控制器的负载压缩机。 APU发动机适于机械接合以加载压缩机以驱动负载压缩机以提供气动动力并且当需要气动动力停止时被分离。 耦合构件对负载压缩机和APU发动机，并且构造成在APU发动机与负载压缩机机械接合的接合位置和APU发动机从负载压缩机脱离的分离位置之间可控地移动。 APU控制器可操作地耦合到负载压缩机，APU发动机，联接构件和预纺装置，并适于接收和响应于转速信号，以控制联接构件在接合位置和脱离位置之间的移动。
