    摘要: An inlet door system includes a duct (114), an inlet door (140), and a plurality of openings (308). The duct is configured to extend from the auxiliary power unit (APU) to an intake opening formed in an outer surface of an aircraft. The duct includes an inlet port (126), an outlet port (128), and a duct sidewall (132) extending between the inlet port and the outlet port. The inlet door includes an inner surface (302), an outer surface (304), and an outer peripheral edge (306) between the inner and outer surfaces. The door is rotationally coupled to the duct, and is configured to selectively rotate between a closed position and a plurality of open positions. The openings extend through the inlet door (140) between the inner surface (302) and outer surface (304), and each opening (308) is disposed adjacent to the outer peripheral edge (306).

    摘要: An inlet door assembly (26) for reducing air pressure loss and enhancing performance of an auxiliary power unit (APU) contained within an aircraft housing is provided. The inlet door assembly includes a duct (34) and a diffuser (36). The duct, which is configured to be movably coupled to an aircraft and to move between open and closed positions, has a flow passage (42) extending therethrough. Air external to the aircraft flows through the duct while it is in the open position, but not while it is in the closed position. The diffuser is coupled to the duct and configured to move therewith. The diffuser has a passage (64) extending therethrough that is in fluid communication with the duct flow passage, and is configured to diffuse the air that flows therethrough.

    摘要: A passive cooling system for an auxiliary power unit (APU) installation on an aircraft is provided. The system is for an auxiliary power unit having at least a compressor portion of a gas turbine engine and an oil cooler contained separately within a nacelle. The system includes the auxiliary power unit housed within the nacelle of the aircraft, an engine exhaust opening defined in the aft portion of the nacelle and communicating with the gas turbine engine, at least a first air inlet duct communicating with a second opening defined in said nacelle and with said compressor portion and the oil cooler is located within a second duct communicating with an opening other than the engine exhaust opening of said nacelle and with the engine exhaust opening. Exterior cooling air and engine exhaust ejected through said engine exhaust opening entrain cooling air through said second duct to said oil cooler, and thus provide engine oil cooling. An exhaust eductor is also provided.
