An exhaust nozzle (38) includes an outer duct (50) surrounding an inner duct (36). The inner duct (36) includes a main outlet (46), and a row of aperture (48) spaced upstream therefrom. The outer duct (50) includes a row of intake (52) at a forward end, an auxiliary outlet (54) at an aft end, and surrounds the inner duct (36) over the apertures to form a bypass channel (56) terminating at the auxiliary outlet (54). A row of flaps (58) are hinged at upstream ends to selectively cover and uncover the apertures (48) for selectively bypassing a portion of exhaust flow from the inner duct (36) through the outer duct (50) in confluent streams from both main and auxiliary outlets (46,54). When the flap (58) cover the apertures, the intake (52) ventilate the bypass channel (56) and discharge flow through the auxiliary outlet (54). |
