초록

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 w...

1. A method of improving air flow through an educted heat exchanger, the method comprising the steps of: providing a gas turbine exhaust flow;flowing the exhaust flow through an exhaust eductor to entrain a heat exchange air flow through a heat exchanger, and then mixing the heat exchange air flow into the exhaust flow, the heat exchange air flow and the exhaust flow intersecting within the exhaust eductor and thereby mixing together; andinjecting pressurized surge bleed air into one of the heat exchange air flow and the gas turbine exhaust flow, wherein...
