Exhaust nozzle for suppressing infrared radiation

摘要: An exhaust nozzle (24 or 28) operative to suppress the InfraRed (IR) signature radiated from high-temperature of an engine (12) which includes inlet conduit adapted for receiving and a plurality adjoined lobes (30) integrally formed in combination with conduit. The are characterized by first second penetrating (60, 62 70, 72) admixing low-temperature gaseous fluid axially staggered respect each other. In preferred embodiment, at least one said (60 62, 70 extends into core region (CR) effect thorough mixing low temperature fluid. Various embodiments such described context multi-stage mixer/ejector (20).
