Abstract
An array of chutes is permanently mounted within the flowpath of an exhaust nozzle of an aircraft jet engine for entraining and mixing ambient air with the exhaust gas so as to reduce the noise level of aircraft, particularly during take-off. In order to provide good engine performance during all modes of jet engine operation, a convergent-divergent flap assembly is arranged downstream from the chutes for controlling the nozzle throat and exit areas when the chutes are closed.
