An engine exhaust nozzle (36) is provided for reducing exhaust noise in an intermediate bypass ratio turbofan engine. The nozzle (36) includes a plurality of scoop ejectors (38) placed equal distances about the circumference of a nozzle outer structure (46). A translatable centerbody (52) is located within the outer structure (46). The annular space between the outer structure (46) and the centerbody (52) define a convergent-divergent exhaust duct (56). Each scoop ejector (38) has a forward inlet (71) and an aft outlet (72). The scoop ejectors are rotata...


[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follow:] [1.] A noise suppression exhaust nozzle for an intermediate bypass ratio aircraft engine, the nozzle comprising:(a) an axisymmetric outer structure having interior sidewalls and a centerbody located within the sidewalls, the area between the centerbody and the sidewalls defining a convergent-divergent exhaust duct for passage of nozzle exhaust;(b) a plurality of scoop ejectors positioned within the nozzle outer structure; each scoop ejector h...
