THRUST REVERSER WITH A DEPLOYMENT-CONTROLLED BLOCKING FLAP

摘要

A thrust reverser device for a turbojet engine nacelle includes a mobile cowl movably mounted to translate between a closed position which the mobile cowl covers grids deflecting some of the air flow of the turbojet engine and an open position in which it opens a passage and uncovers the grids. The mobile cowl is associated with a blocking flap to pivot between a retracted position and a blocking position corresponding to the open position of the mobile cowl. The blocking flap is fitted with at least one lever forming a drive mechanism which includes at least one adjustable-stiffness shock absorber.

1. A thrust reversal device for a turbojet engine nacelle comprising:
at least one cowl movably mounted in translation between a closing position in which said cowl provides an aerodynamic continuity of the nacelle and covers diverting means for diverting at least a part of an air flow of a turbojet engine, and an opening position in which said cowl opens a passage in the nacelle and uncovers said diverting means, said at least one cowl being associated with at least one blocking flap pivotally mounted between a retracted position corresponding to the closing position of said cowl and a blocking position corresponding to the opening position of said cowl, in the blocking position, wherein said at least one blocking flap obstructs at least partially an air circulation path of the nacelle, said blocking flap being equipped with at least one driving mechanism forming a lever, and said driving mechanism comprising at least one adjustable-stiffness damper.
