The invention discloses a thrust reverser locking mechanism and an aero-engine comprising the thrust reverser locking mechanism, the thrust reverser locking mechanism comprises a shell, a liquid supply part and a locking rod, the shell comprises an inner cavity, a liquid inlet and a liquid outlet which communicate with one another, the first end of the locking rod is arranged in the inner cavity, and the second end of the locking rod is arranged in the liquid inlet; the second end of the locking rod extends to the outside of the shell and can be connected with the movable outer cover, and the locking rod is arranged to be switched between a locking position and an unlocking position according to the pressure of the liquid inlet side; at the locking position, the locking rod is jointed with the movable outer cover, and the thrust reverser locking mechanism is in a locking state; and at the unlocking position, the locking rod moves towards the side away from the movable outer cover in the axis direction of the locking rod, and the reverse thrust device locking mechanism is in an unlocking state. The locking rod is hydraulically driven to move, the working principle is simple, the stability is high, the hydraulic transmission structure is simple, electrical control equipment such as an electromagnetic valve does not need to be arranged, complex circuit layout does not need to be designed either, and the production and assembly cost is effectively reduced.
本发明公开了一种反推装置锁定机构及包括其的航空发动机,反推装置锁定机构包括壳体、供液部和锁定杆,壳体包括相互连通的内部腔室、进液口和出液口,锁定杆的第一端设置在内部腔室内,锁定杆的第二端延伸至壳体的外部并能够与移动外罩接合,锁定杆被设置为根据进液口侧的压力在锁定位置和解锁位置之间切换;在锁定位置,锁定杆与移动外罩接合,反推装置锁定机构处于锁定状态;在解锁位置,锁定杆沿其轴线方向朝向远离移动外罩的一侧移动,反推装置锁定机构处于解锁状态。本发明通过液压驱动锁定杆的移动,工作原理简单且稳定性高,而且液压传动的结构简单,不用设置电磁阀等电气控制设备,也不用设计复杂的电路布局,有效降低生产和组装成本。
