The present invention concerns a sliding door, which, for example, can be guided on three rollers on the door side in rails on the aircraft structure. Locking of such a cargo door occurs by movement of the cargo door parallel to the aircraft X-axis with the locking pins in corresponding sleeves situated on the aircraft structure. In order to guarantee this, the door opening must be larger than the door itself. The gap produced by this is now closed by means of a locking element that clamps the door. This permits a light structure of the cargo door and therefore a weight saving.
1. Aircraft door for closure of an opening in a shell of an aircraft,
wherein the aircraft door is movable along a longitudinal direction of the aircraft, and
wherein the opening in the shell of the aircraft is larger than the outer surface of the aircraft door, so that a gap is present between an edge of the aircraft door and an edge of the opening when the aircraft door closes the opening,
a first locking element being provided, the first locking element being arranged in the gap for locking of the aircraft door in the opening, the first locking element closing the gap to form a portion of the shell of the aircraft and translating parallel and perpendicular to the aircraft door when the aircraft door closes the opening.
2. The aircraft door of claim 1 ,
wherein at least a second locking element is provided, so that the aircraft door is locked by means of a displacement along the longitudinal direction of the aircraft in the opening.
3. The aircraft door of claim 2 ,
wherein, for locking of the aircraft door, the aircraft door is first arrangable in the opening, the aircraft door is then displaceable in the opening along the longitudinal direction of the aircraft for locking of at least the second locking element, and the first locking element is then arrangable in the gap for locking.
4. The aircraft door of claim 1 ,
wherein the aircraft door is displaceable between a closed state, in which the aircraft door is fully locked in the opening, and an opened state, in which the aircraft door is movable relative to the opening on an outside of the shell, so that a large region of the opening is not covered by the aircraft door, and
wherein, for guiding of the aircraft door between the closed state and the open state, holding elements are provided which are adopted for an engagement with an at least one guide rail arranged on the shell.
5. The aircraft door of claim 4 ,
wherein the holding elements are operable for cooperation with the at least one guide rail so that guiding of the aircraft door along the longitudinal direction of the aircraft and relative to the force of gravity is ensured.
6. The aircraft door of claim 5 ,
wherein the at least one guide rail is operable for guiding of the aircraft door, so that the aircraft door is displaceable from the closed state for unlocking first along the longitudinal axis of the aircraft by a first amount, is movable along a normal to the shell by a second amount for removal of the aircraft door from the opening, and is movable for exposure of the opening along the longitudinal axis of the aircraft by a third amount to the opened state on the outside of the shell; and
wherein the aircraft door executes no rotational movement.
