LOCKING/UNLOCKING DEVICE FOR A ONE-PIECE COWL OF A THRUST REVERSER OF A TURBOJET ENGINE NACELLE

摘要

An assembly for a turbojet engine includes a pylon, a nacelle supported by the pylon, and a locking device interposed between the pylon and a cowl of the nacelle. The cowl slides between operating and maintenance positions. The locking device is movable between active and inhibited positions, and the device allows an operation mode in the active position and a maintenance mode in the inhibited position. In particular, the locking device comprises a rocker to maintain the cowl to the pylon, and the rocker includes an inhibiting lever and an activation lever. The inhibiting and activation levers are mounted on a switching shaft of the locking device. The inhibiting lever is set in rotation through an actuator, providing direct access from a bypass flow duct in the active position while the activation lever is set in rotation from the bypass duct in the inhibited position.

主权项

1. An assembly for a turbojet engine, comprising:
a pylon; a nacelle supported by said pylon and surrounding the turbojet engine so as to define a bypass flow duct into which a secondary air flow flows, said nacelle comprising at least one thrust reverser device comprising a one-piece cowl slidably mounted alternately between an operating position and a maintenance position of the nacelle; and at least one locking/unlocking device of said one-piece cowl, the device being interposed between said pylon and said cowl, and said device being alternately movable between an active position and an inhibited position, wherein the active position allows an operation mode of the nacelle and the inhibited position allows a maintenance mode of said nacelle, wherein said at least one locking/unlocking device comprises retention means of said one-piece cowl, and a switching rocker of the retention means comprises at least one inhibiting lever of the retention means and at least one activation lever of the retention means, said inhibiting and activation levers being mounted on a switching shaft of said locking/unlocking device, and wherein said inhibiting lever is configured to set in rotation through actuating means directly accessible from the bypass flow duct when said locking/unlocking device is in the active position, and said activation lever is configured to set in rotation from the bypass duct when said locking/unlocking device is in the inhibited position.
