초록

A fan-jet gas turbine engine heat exchanger is cooled by fan air taken from the fan duct at a relatively high pressure region of the fan nozzle upstream of the fan nozzle\s throat and exhausted into a relatively low pressure region of the fan nozzle upstream of the throat. One embodiment provides a cooling air duct with a forward facing scoop at the duct\s inlet for capturing cooling air and providing greater dynamic pressure recovery. A diffuser is located upstream of the heat exchanger and a nozzle is located downstream of the heat exchanger with a noz...
