    • A thrust reverser for a turbo-fan engine having an improved system for security against inflight inadvertent deployment.
      The reverser has two pivoting doors (1,2) for use on engines mounted on an aircraft rear fuselage or under the aircraft wing.
      The pivoting doors (1,2) are positioned forward of an aft ring structure (3) that is essentially the nacelle exit nozzle in forward thrust mode.
      The pivoting doors (1,2) are actuated by a hydraulic actuator and are locked and unlocked by hook locks (9,8) operated by an electric solenoid on one side of the door and a small hydraulic actuator on the opposite side.
      The two locking systems are completely independent, thereby assuring that an inadvertent in-flight deployment will not occur as a result from failure, faulty command or maintenance malpractice.
    • 涡轮风扇发动机的推力反向器具有改进的系统,用于防止机上无意间部署。 反向器具有两个枢转门(1,2),用于安装在飞机后机身或飞机机翼下的发动机。 枢转门(1,2)位于后环形结构(3)的前方,其基本上是前向推力模式下的机舱出口喷嘴。 枢转门(1,2)由液压致动器致动,并且通过由门的一侧上的电磁螺线管操作的钩锁(9,8)和在相对侧的小液压致动器来锁定和解锁。 两个锁定系统是完全独立的,从而确保由于故障,命令错误或维护不当导致的无意中的飞行中部署。
