An exhaust nozzle (38) includes an exhaust duct (36) with an outlet (46) and a row of radial apertures (48) upstream therefrom. A radial frame (58) surroun ds the duct (36) upstream from the apertures (48). A row of flaps (56) are hing ed to the frame (58) to selectively cover and uncover the apertures (48) for controlling exhaust flow discharged therethrough. An arcuate unison bar (66) surrounds the duct (36) adjacent to the frame (58) and includes circumferentially spaced apart cam followers (68) engaging corresponding cam s (64) affixed to the flaps. An actuator (70) is joined to the bar (66) for selective rotation thereof between opposite first and second directions to pivot open and closed the flaps atop the apertures (48).
