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 t

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).

1. A method for opening and closing a thrust reverser door of a jet engine, comprising: providing at least one actuator for opening and closing the thrust reverser door;providing at least one locking mechanism for selectively locking the thrust reverser door in a 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; the at least one first locking element engageable with the at least one second locking element for selectively locking the thrust reverser door in a closed position;providing the at least one first locking element with an unloading element and a force providing element separate from any forces generated by the at least one actuator;pulling the thrust reverser door in a closing direction at a beginning of the opening process by applying a force from the force providing element against the unloading element of the first locking element to move the first locking element in a closing direction to unload the at least one first locking element from the at least one second locking element for disengagement of the at least one first locking element from the at least one second locking element;releasing the locking mechanism by disengaging the at least one first locking element from the at least one second locking element so that the thrust reverser door can be moved to an open position. 2. The method of claim 1, and further comprising attaching a swivel arm to the second locking element to swivel the second locking element between a locking position and an unlocking position. 3. The method of claim 2, and further comprising providing an additional second locking element of an adjacent thrust reverser door and attaching the two second locking elements to opposite ends, respectively, of the swivel arm. 4. The method of claim 3, and further comprising providing that the first locking element is essentially L-shaped and, on a portion engaging the second locking element, providing a securing element for the second locking element. 5. The method of claim 3, and further comprising providing that the first locking element is at least one chosen from a hook and an eye and the second locking element is the other of the hook and the eye. 6. The method of claim 1, and further comprising providing an additional second locking element of an adjacent thrust reverser door and attaching the two second locking elements to opposite ends, respectively, of the swivel arm. 7. The method of claim 1, and further comprising providing that the first locking element is essentially L-shaped and, on a portion engaging the second locking element, providing a securing element for the second locking element. 8. The method of claim 1, and further comprising providing that the first locking element is at least one chosen from a hook and an eye and the second locking element is the other of the hook and the eye. 9. The method of claim 1, wherein, the force is applied in a force direction essentially parallel to a longitudinal axis of the jet. 10. The method of claim 9, and further comprising providing the unloading element with at least one unloading surface facing in an opening direction of the thrust reverser door, the unloading surface comprising at least one chosen from an inclined surface and a curved surface; moving a force arm in the force direction different from the closing direction to engage a roller of the force arm against the unloading surface and convert the force in the force direction to a closing force in the closing direction against the unloading surface and force the unloading element in the closing direction. 11. The method of claim 10, wherein the force direction is normal to the closing direction. 12. The method of claim 11, and further comprising applying the force without operating the actuator for opening and closing the thrust reverser door. 13. The method of claim 12, wherein the unloading surface of the unloading element is separate from a surface of the first locking element that engages the second locking element. 14. The method of claim 13, wherein the unloading surface forms an inclined plane simple machine in operation with the roller. 15. The method of claim 1, and further comprising providing the unloading element with at least one unloading surface facing in an opening direction of the thrust reverser door, the unloading surface comprising at least one chosen from an inclined surface and a curved surface; moving a force arm in a force direction different from the closing direction to engage a roller of the force arm against the unloading surface and convert the force in the force direction to a closing force in the closing direction against the unloading surface and force the unloading element in the closing direction. 16. The method of claim 15 wherein the unloading surface of the unloading element is separate from a surface of the first locking element that engages the second locking element. 17. The method of claim 16, wherein the force direction is normal to the closing direction. 18. The method of claim 17, and further comprising applying the force without operating the actuator for opening and closing the thrust reverser door. 19. The method of claim 18, wherein the unloading surface forms an inclined plane simple machine in operation with the roller. 20. The method of claim 1, and further comprising applying the force without operating the actuator for opening and closing the thrust reverser door.
