The invention provides a locking mechanism of a retractable actuator cylinder for a ram air turbine and the retractable actuator cylinder. Comprising a folding and unfolding actuator cylinder up-down locking mechanism and a triggering mechanism. The trigger mechanism is arranged at the tail end of the retracting and releasing actuator cylinder and connected with a lock piston in the retracting and releasing actuator cylinder up-down position locking mechanism, when unlocking is needed, the trigger mechanism pulls the lock piston to move by a certain stroke in the axial direction, it is guaranteed that the retracting and releasing actuator cylinder is unlocked and unfolded in place, and then the ram air turbine enters the working position; when recycling and locking are needed, the retracting and releasing actuating cylinder is hydraulically driven, so that the up-down locking mechanism is located at the up-locking position, and meanwhile, the triggering mechanism is automatically reset to the locking state. The design structure is compact, the folding and unfolding actuating cylinder can be unlocked with smaller driving force, the ram air turbine can be unfolded to the working position more easily, smaller unlocking driving force can be provided by the unfolding electromagnet with smaller size, and then the mounting space and weight of the ram air turbine on a machine are reduced.

    本发明提出了一种冲压空气涡轮用收放作动筒的锁机构及收放作动筒;包括收放作动筒上下位锁定机构以及触发机构;触发机构设置于收放作动筒的尾端,并与收放作动筒上下位锁定机构内的锁活塞相连,当需要解锁时,触发机构拉动锁活塞沿轴向运动一定行程,保证收放作动筒解锁展开到位,进而使冲压空气涡轮进入工作位置;当需要回收锁定时,收放作动筒通过液压驱动,使得上下位锁定机构处于上位锁定位置,同时触发机构自动复位至锁定状态。本发明设计结构紧凑,可以实现以更小的驱动力解锁收放作动筒,使冲压空气涡轮更容易的展开至工作位置,更小的解锁驱动力可以由更小尺寸的展开电磁铁提供,进而减小冲压空气涡轮在机上的安装空间以及重量。
