ABSTRACT:
This disclosure describes an arrangement for cooling the exhaust nozzle of a gas turbine engine by selectively diverting the unheated total engine air flow directly to the exhaust nozzle of the engine. After the total air flow impinges on the back surface of the exhaust nozzle to rapidly cool the nozzle, the air is redirected back to the fan and the core engine for supporting combustion and to provide cooling in a generally conventional manner.
