Abstract
An exhaust nozzle for a gas turbine engine includes a converging inlet duct disposed in flow communication with a diverging outlet duct at a throat therebetween. An ejection slot is disposed at the throat, and compressed air from the engine is selectively injected through the slot for fluidically varying flow area at the throat for exhaust gases from the engine.
Claims13
