초록

Cooling of the hot surfaces of the exhaust nozzle of a fan jet engine and purging of the nacelle is attained by a booster pump mounted in exhaust nozzle structure and the booster pump having an ejector driven by localized fan air existing in the engine cooling path extracted from the fan of the engine for pumping nacelle air and mixing the egressing fluid in a mixing chamber and diffuser disposed in fluid communication with booster pump which is then dumped into a plenum within the exhaust nozzle structure for feeding film cooling holes formed in the hot...
