    Abstract: A low-leakage seal assembly for a turbomachine's combustor-turbine interface. A turbomachine includes a combustion chamber that receives compressed air for combustion from a compressor. The combustion chamber is defined by a combustion liner terminating in a seal ring where the seal ring has an enlarged head that is thicker than the remainder of the seal ring. A transition liner directs combustion gases from the combustion chamber to the turbine and has three walls forming a cavity with an open end. The seal ring extends through the open end and the head nests in the cavity. The transition liner and the seal ring are parts of a low-leakage seal assembly that is exposed on one side to the compressed air and that is exposed on another side to the combustion gases.

    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.
