    • PROBLEM TO BE SOLVED: To provide a thrust reverser assembly and operation suitable for an high-bypass turbofan engine.SOLUTION: A thrust reverser assembly 12C includes a translating cowl 34A mounted to a nacelle 12 of an engine 10 and adapted to translate in an aft direction of the engine. The translating cowl has a radially inner wall that defines a radially outer flow surface of a bypass duct 30 of the engine. The thrust reverser assembly includes blocker doors 34c axially guided adjacent first ends thereof by a fixed structure and pivotally and slidably connected along lengths thereof to the inner wall of the translating cowl so that the translation of the translating cowl in the aft direction causes each blocker door to move from a stored position to a deployed position as a result of the blocker door sliding at its first end relative to the fixed structure and sliding along its length relative to the inner wall of the translating cowl.
    • 要解决的问题:提供一种适用于高旁通涡扇发动机的推力反向器组件和操作。解决方案:推力反向器组件12C包括安装在发动机10的机舱12上并适于在后方翻转的平移整流罩34A 发动机方向 平移整流罩具有限定发动机的旁路管道30的径向外部流动表面的径向内壁。 推力反向器组件包括阻挡门34c,其通过固定结构相对于其第一端轴向地引导,并且沿着其长度可枢转地和可滑动地连接到平移整流罩的内壁,使得平移整流罩在后方向上的平移使每个阻塞门 由于阻挡门在其第一端相对于固定结构滑动并相对于平移罩的内壁沿其长度滑动,从存储位置移动到展开位置。
