Abstract

A wing for an aircraft, including a main wing, a slat, and a connection assembly movably connecting the slat to the main wing, the slat movable between a retracted and at least one extended position. The connection assembly includes an elongate slat track. A wing has a connection assembly without requiring the front spar being penetrated. The slat track has a first end mounted to the slat and a second end guided at the main wing for movement along a predetermined path extending in a direction from a front spar to a leading edge of the main wing and from a lower side to an upper side of the main wing. Between the first and second ends the slat track is mounted to the main wing allowing translation of the slat track and rotation of the slat track about a first axis of rotation parallel to the leading edge.

First claim

The invention claimed is:

1. A wing for an aircraft, comprising:
a main wing;
a slat;
a connection assembly movably connecting the slat to the main wing, such that the slat is movable between a retracted position and at least one extended position;
the connection assembly comprising an elongate slat track fixedly mounted to the slat and movably mounted to the main wing;
the slat track comprising a first end mounted to the slat and a second end guided at the main wing for movement along a predetermined path;
the predetermined path extending in a direction from a front spar to a leading edge of the main wing and from a lower side to an upper side of the main wing;
wherein, between the first and second ends, the slat track is mounted to the main wing by a translational-rotational bearing that allows translation of the slat track along a longitudinal direction of the slat track and rotation of the slat track about a first axis of rotation parallel to the leading edge, and that inhibits translation of the slat track normal to the longitudinal direction;
wherein the translational-rotational bearing is formed as a pair of rollers between which the slat track is guided from opposite sides, wherein the rollers have roller axes of rotation in parallel to the leading edge.

2. The wing according to claim 1 , wherein the slat track is driven by a drive unit for movement of the second end along the predetermined path.

3. The wing according to claim 1 , wherein the predetermined path is formed convex with respect to the leading edge.

4. The wing according to claim 1 , wherein the predetermined path is formed as a segment of a circle, wherein the circle has a center located between the front spar and the predetermined path.

5. The wing according to claim 1 , wherein the predetermined path is defined by a trace.

6. The wing according to claim 1 , wherein the predetermined path is defined by a linkage.

7. The wing according to claim 6 , wherein the linkage comprises a first link, wherein the first link is mounted to the main wing rotatably about a second axis of rotation, and wherein the first link is mounted to the second end of the slat track rotatably about a third axis of rotation.

8. The wing according to claim 7 , wherein the drive unit drives the first link for rotation about the second axis of rotation.

9. The wing according to claim 8 , wherein the linkage comprises a second link driven by the drive unit and mounted to the first link rotatably about a fourth axis of rotation.

10. The wing according to claim 9 , wherein the linkage comprises a third link mounted to the main wing rotatably about a fifth axis of rotation and mounted to the second link rotatably about a sixth axis of rotation.

11. The wing according to claim 10 , wherein the third link is driven by the drive unit about the fifth axis of rotation.

12. The wing according to claim 10 , wherein the first, second, third, fourth, fifth, and sixth axes of rotation extend in parallel to one another.

13. An aircraft comprising a wing according to claim 1 .

14. A connection assembly for connecting a slat to a main wing of an aircraft such that the slat is movable between a retracted position and at least one extended position, the connection assembly comprising:
an elongate slat track for fixedly mounting to the slat and for movably mounting to the main wing;
wherein the slat track has a first end for mounting to the slat and a second end configured to be guided at the main wing for movement along a predetermined path,
wherein the predetermined path extends in a direction from a front spar to a leading edge of the main wing and from a lower side to an upper side of the main wing,
wherein between the first and second ends the slat track is configured to be mounted to the main wing by a translational-rotational bearing that allows translation of the slat track along a longitudinal direction of the slat track and rotation of the slat track about a first axis of rotation parallel to the leading edge, and that inhibits translation of the slat track normal to the longitudinal direction;
wherein the translational-rotational bearing is formed as a pair of rollers between which the slat track is guided from opposite sides, wherein the rollers have roller axes of rotation in parallel to the leading edge.
