Abstract

An aircraft wing includes a main wing having an outer skin defining an interior space of the main wing, a slat, and a connection assembly for movably connecting the slat to the main wing, such that the slat is movable in a predefined motion between a retracted position and at least one extended position. The assembly includes an elongate guide arranged within the interior space, a bearing at least partly arranged outside the interior space, an elongate slat track with a first end section connected to the slat and a second end section movably and rotatable connected to the guide, such that the second end section is movable along a predefined pathway defined by the guide while being connected to the main wing. An intermediate section of the slat track is movably and rotatably supported on the main wing, such that the guide and the bearing support the predefined motion.

First claim

The invention claimed is:

1. A wing for an aircraft, comprising:
a main wing having an outer skin defining an interior space of the main wing;
a slat; and
a connection assembly for movably connecting the slat to the main wing, such that the slat is movable in a predefined motion between a retracted position and at least one extended position,
wherein the connection assembly comprises an elongate guide being arranged within the interior space of the main wing,
wherein the connection assembly comprises a bearing, which is at least partly arranged outside the interior space of the main wing,
wherein the connection assembly comprises an elongate slat track,
wherein a first end section of the slat track is connected to the slat,
wherein a second end section of the slat track is movably and rotatably connected to the guide, such that the second end section of the slat track is movable along a predefined pathway defined by the guide while being connected to the main wing via the guide,
wherein an intermediate section of the slat track is movably and rotatably supported on the main wing by the bearing, such that the guide and the bearing support the predefined motion, and
wherein the main wing comprises a front spar, such that the front spar and the outer skin of the main wing define a front portion of the interior space, wherein the guide is fully arranged within the front portion of the interior space.

2. The wing according to claim 1 , wherein the connection assembly and the slat track are configured, such that the second end section of the slat track remains within the front portion of the interior space, if the slat is moved to the retracted position.

3. The wing according to claim 1 , wherein a cover element is arranged outside the outer skin of the main wing, such that the cover element at least partly covers at least the part of the bearing being arranged outside the interior space of the main wing.

4. The wing according to claim 1 , wherein the guide is a straight guide, such that the pathway is a straight pathway.

5. The wing according to claim 1 , wherein the guide is a curved guide, such that at least a section of the pathway is curved.

6. The wing according to claim 1 , wherein the guide is configured as a roller bearing guide.

7. The wing according to claim 1 , wherein the bearing is a roller bearing comprising a roller pair, and
wherein at least one roller of the roller pair is at least partly arranged outside the interior space of the main wing.

8. The wing according to claim 7 , wherein the intermediate section of the slat track is guided by the roller pair, such that each roller of the roller pair supports an opposite side of the intermediate section of the slat track.

9. A wing for an aircraft, comprising:
a main wing having an outer skin defining an interior space of the main wing;
a slat; and
a connection assembly for movably connecting the slat to the main wing, such that the slat is movable in a predefined motion between a retracted position and at least one extended position,
wherein the connection assembly comprises an elongate guide being arranged within the interior space of the main wing,
wherein the connection assembly comprises a bearing, which is at least partly arranged outside the interior space of the main wing,
wherein the connection assembly comprises an elongate slat track,
wherein a first end section of the slat track is connected to the slat,
wherein a second end section of the slat track is movably and rotatably connected to the guide, such that the second end section of the slat track is movable along a predefined pathway defined by the guide while being connected to the main wing via the guide,
wherein an intermediate section of the slat track is movably and rotatably supported on the main wing by the bearing, such that the guide and the bearing support the predefined motion, and
wherein a center line of the guide differs from a center line of the slat track, at least if the slat is moved to the retracted position.

10. An aircraft comprising at least one wing according to claim 1 .
