    • 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).
    • 排气喷嘴(38)包括围绕内导管(36)的外导管(50)。 内导管(36)包括主出口(46)和在其上游隔开的一排孔(48)。 外管(50)包括在前端的一排进气口(52),在后端的辅助出口(54),并且在所述孔的上方围绕内管(36)以形成旁路通道(56) 在辅助出口(54)处。 一排挡板58在上游端被铰接以选择性地覆盖和露出孔48,以选择性地绕过来自内部导管36的一部分排气流通过外部导管50, 和辅助出口(46,54)。 当翼片(58)覆盖孔时,入口(52)使旁路通道(56)通气并通过辅助出口(54)排出流体。

    • 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) surrounds the duct (36) upstream from the apertures (48). A row of flaps (56) are hinged 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 cams (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).
    • 排气喷嘴(38)包括具有出口(46)和在其上游的一排径向孔(48)的排气管道(36)。 径向框架(58)围绕孔(48)上游的管道(36)。 一排翼片(56)铰接到框架(58)上以选择性地覆盖和露出用于控制从其排出的排气流的孔(48)。 弧形协调杆(66)围绕与框架(58)相邻的管道(36),并且包括与固定到翼片上的相应凸轮(64)相啮合的周向间隔开的凸轮从动件(68)。 致动器(70)连接到杆(66),用于在相对的第一和第二方向之间选择性地旋转,以在孔(48)顶部枢转打开和关闭翼片。
