The invention relates to a locking device () that includes at least one locking system (), intended to be placed on a first moving element (), and a retaining member (), intended to be placed on a second moving element (), the locking system () having a first hook () designed to engage with the retaining member so as to lock the locking device (). The locking system () includes at least a second hook () set back from the first hook () so as to engage with the retaining member in the event of the first hook () breaking.

Locking device

A turbojet-engine thrust reverser is provided with thrust reverser door assemblies each having a pivoting thrust reverser door ( ). The thrust reverser door is connected to two pivots ( ) that rest on a support fitting ( ) to constitute a structural frame that is attached to longitudinal beam cowling portions ( ) and a downstream cowling portion ( ) of a stationary thrust-reverser structure in order to constitute a rigid assembly between the upstream and downstream cowling portions ( ). At least one primary mechanical lock ( ) is placed on at least one longitudinal side of the door ( ) and the interface loads of the lock ( ) are absorbed by the beam cowling portions ( ).

Turbojet-engine thrust reverser with doors mounted on centered pivots

A thrust reverser for a turbojet engine is provided with at least one displaceable assembly including a displaceable cowling portion and a flap. The displaceable cowling portion and the flap each subtend stationary upstream and downstream cowling portions such that the displaceable cowling portion forms a portion of the external engine cowling covering a reverse thrust opening and the flap forms a portion of the outer boundary of the gas flow in a forward thrust position. In a reverse thrust position, the reverse thrust opening is uncovered, and the displaceable cowling portion and the flap are displaced downstream such that the displaceable cowling portion extends downstream, parallel to the longitudinal engine axis and above, without interference, the downstream cowling portion. The flap engages in rolling contact with a plurality of rolling elements supported by an upstream end of the stationary downstream cowling portion and pivots and so as to block the gas flow duct and redirect the gas flow outward though the vane-cascades.
