摘要： A simplified actuation system for positioning the divergent flaps of a vectorable two-dimensional exhaust nozzle is disclosed. The system includes lever arms having cam surfaces pivotably attached to diverent flap crank shafts. An actuator is pinned to the nozzle sidewall and operably connected to a slider bar which has two cam followers at either end which are fixed with respect to each other and enage the cam surfaces of the lever arms. The slider bar is slideably engaged to the nozzle sidewall so as to permit radial movement with respect to the nozzle centerline. As the convergent flaps are moved the lever arms are translated axially and the cam followers in cooperation with the cam surfaces on the lever arms schedule the relative angle between the divergent flaps and thereby the exit area of the nozzle. Vectoring is provided operating the actuators which translate the cam followers in the radial direction, up or down, thereby rotating the divergent flaps so that they are pitched up or down in unison.

摘要： Nacelle installation having devices for constraining hot core exhaust gas from flowing over the trailing portion of a highly swept pylon supporting a high bypass turbofan engine. The devices can comprise a pylon ejector, a core nozzle shroud or a plurality of vortex generators and are disposed generally in the region adjacent the intersection of the core nozzle exit of the engine and the pylon shelf portion of the pylon.

摘要： A propulsion nozzle having a substantially cylindrical translatable shroud partially defining an outer flow duct and an articulated plug mounted within the shroud to partially define an inner coannular flow duct. A variable position valve comprises the downstream portion of the common wall between the ducts. The valve cooperates with the shroud and the plug, as required, to form a variable area throat for either flow duct, or both.

摘要： A double bypass, variable cycle gas turbofan engine is provided with a variable area bypass injector which varies the area through which the inner bypass stream is injected into the outer bypass stream. The bypass injector comprises an upstream variable area, double bypass selector valve, the position of which determines whether the engine will operate in the single or double bypass mode, and a downstream static pressure valve which defines an optimum flow path for injecting the inner bypass stream into the outer bypass stream. The ability to vary the area through which the inner bypass stream is injected into the outer bypass stream permits the static pressure valve to operate as an ejector and permits control of the two bypass air streams through creation of a static pressure balance at the exit of the variable area bypass injector. The ability to control the bypass operating mode and the static pressure balance at the confluence of the two bypass streams eliminates the necessity for one exhaust duct and one exhaust nozzle, thereby reducing complexity and weight, and improves the engine-aircraft integration by reducing engine and nozzle diameters.
摘要翻译：双旁路，可变循环气体涡轮风扇发动机设置有可变区域旁路喷射器，其改变将内部旁路流注入到外部旁路流中的区域。旁路喷射器包括上游可变区域，双旁路选择阀，其位置确定发动机是以单旁路还是双旁路模式运行;以及下游静压阀，其限定用于喷射内部旁路流的最佳流动路径进入外部旁路流。改变内部旁路流注入外部旁路流的区域的能力允许静压力阀作为喷射器操作，并允许通过在出口处产生静压力平衡来控制两个旁路气流可变区域旁路注射器。控制旁路操作模式的能力和两个旁路流汇合时的静压力平衡消除了一个排气管和一个排气喷嘴的必要性，从而降低了复杂性和重量，并通过减少发动机和喷嘴直径。
