A gas turbine engine exhaust nozzle (38) includes a row of laterally sinuous chevrons (42) extending from an aft end of an exhaust duct (40). The chevrons (42) have radially outer and inner surfaces (44, 46) bound by a laterally sinuous trailing edge (48) ...

A segmented exhaust nozzle for attenuating noise from a turbofan jet engine without adversely impacting the operability or operability limit related performance of the engine. The exhaust nozzle includes spaced apart fan nozzle inner and outer walls which ...

Disclosed is a means for reducing jet engine exhaust noise wherein mixing is enhanced between adjacent exhaust flows and between exhaust flow and free-stream flow. The device does so with a very small degradation in aircraft performance. The device is a se...
