    • An exhaust section of a reaction engine, especially for aircraft, including a fixed pipe and a nozzle pipe carried by the fixed pipe. Pins project from each pipe into slots in the other pipe, and each of a plurality of actuating elements extends between, and is pivoted to, the exteriors of both pipes. The actuating elements are adjustable lengthwise to pivot the nozzle pipe with respect to the fixed pipe. There may be four pairs of pins and slots, and four actuating elements. Each actuating element may include two cooperating actuating members, one of the members being pivoted to the fixed pipe and the other member being pivoted to the nozzle pipe. The actuating members may be a hydraulic piston/cylinder device or a threaded spindle and nut arrangement. Means are provided for operating the actuating elements of each diametrically-opposed pair in opposite directions. The pins and slots may be carried by supporting arms projecting longitudinally from the pipes.
    • 反应发动机的排气部分,特别是用于飞机,包括固定管和由固定管承载的喷嘴管。 引脚从每个管道突出到另一个管道中的槽中,并且多个致动元件中的每个致动元件在两个管道的外部之间延伸并且枢转到两个管道的外部。 致动元件可纵向调节以使喷嘴管相对于固定管枢转。 可能有四对销和槽,以及四个致动元件。 每个致动元件可以包括两个配合的致动构件,其中一个构件枢转到固定管,另一个构件枢转到喷嘴管。 致动构件可以是液压活塞/缸装置或螺纹主轴和螺母装置。 提供了用于在相反方向上操作每个直径相对对的致动元件的装置。 销和槽可以由从管道纵向突出的支撑臂承载。
