Abstract
A device for opening and closing a thrust reverser door (3) of a jet engine includes at least one actuator and at least one locking mechanism (10) including at least one first locking element (11) arranged on the thrust reverser door (3) and at least one second locking element (13) arranged on the thrust reverser structure (5). To open the locking mechanism (10) against higher internal pressures in the thrust reverser (1) without increasing a power of the actuator or requiring the operation of the latter, the device includes, in addition to the actuator, at least one unloading mechanism (20) which is coupled to the locking mechanism (10).
Claims16
A device for opening and closing a thrust reverser door of a jet engine, comprising:
- at least one actuator for opening and closing the thrust reverser door;
- at least one locking mechanism for selectively locking the thrust reverser door in the closed position, the at least one locking mechanism including at least one first locking element arranged on the thrust reverser door and at least one second locking element arranged on a thrust reverser structure;
- at least one unloading mechanism for locking and unlocking the locking mechanism.
A method for opening and closing a thrust reverser door of a jet engine, comprising:
- pulling the thrust reverser door in a closing direction at a beginning of the opening process by applying a force against an unloading element of a first locking element to move the first locking element in a closing direction to unload an associated locking mechanism;
- releasing the locking mechanism so that the thrust reverser door can be moved to an open position.
