Abstract

A wing for an aircraft, including a main wing, and a leading edge high lift assembly including a high lift body, and a connection assembly connecting the high lift body to the main wing such that the high lift body is movable relative to the main wing between stowed and deployed positions. The connection assembly includes a first connection element mounted to the high lift body and movably mounted to the main wing. The connection assembly includes a second connection element mounted to the high lift body spaced apart from the first connection element in a span direction, and movably mounted to the main wing. The connection assembly includes an additional support device arranged spaced apart from the first and second connection elements and configured to support the high lift body at the main wing against movement or deformation of the high lift body relative to the main wing.

First claim

The invention claimed is:

1. A wing for an aircraft, comprising
a main wing, and
a leading edge high lift assembly comprising
a high lift body, and
a connection assembly connecting the high lift body to the main wing such that the high lift body is movable relative to the main wing between a stowed position and a deployed position,

wherein the connection assembly comprises a first connection element that is mounted to the high lift body and that is movably mounted to the main wing,
wherein the connection assembly comprises a second connection element that is mounted to the high lift body in a position spaced apart from the first connection element in a span direction, and that is movably mounted to the main wing,
wherein the connection assembly comprises an additional support device arranged spaced apart from the first and second connection elements and configured to support the high lift body at the main wing against movement or deformation of the high lift body relative to the main wing
wherein the additional support device comprises a hold down device configured to support the high lift body at the main wing against upwards movement of the high lift body relative to the main wing when the high lift body is in the stowed position,
wherein the hold down device comprises a first stop element mounted to the high lift body and a second stop element mounted to the main wing,
wherein the first and second stop elements are configured to rest against one another when the high lift body is in the stowed position, and
wherein the additional support device comprises a lateral support device configured to support the high lift body at the main wing against spanwise movement of the high lift body relative to the main wing when the high lift body is moved between the stowed position and the deployed position.

2. The wing according to claim 1 , wherein the additional support device is arranged between the first connection element and the second connection element.

3. The wing according to claim 1 ,
wherein the first and second stop elements are configured to rest against one another within a contact plane, and
wherein the contact plane extends or has a share in a plane spanned by the span direction and a chord direction.

4. The wing according to claim 1 ,
wherein the lateral support device comprises a roller or slide bearing including at least one roller or slide pad mounted to one of the high lift body and the main wing, and engaging a corresponding guide surface at the other one of the high lift body and the main wing, and
wherein at least one of the guide surface or a rotation axis of the roller extend in a chord plane spanned by a chord direction and a wing thickness direction.

5. The wing according to claim 3 ,
wherein the lateral support device comprises a first blade mounted to the high lift body and having a first guide surface at a first side and a second guide surface at an opposite second side, and a pair of rollers or slide pads mounted to the main wing and engaging at least one of the first or second guide surfaces from opposite sides, or
wherein the lateral support device comprises a first blade and a second blade both mounted to the high lift body in parallel to one another and having a first guide surface and a second guide surface facing towards each other, and a roller or slide pad mounted to the main wing and guided between the first and second blades in engagement with at least one of the first guide surface or the second guide surface, or
wherein the lateral support device comprises a first blade mounted to the main wing and having a first guide surface at a first side and a second guide surface at an opposite second side, and a pair of rollers or slide pads mounted to the high lift body and engaging at least one of the first or second guide surfaces from opposite sides, or
wherein the lateral support device comprises a first blade and a second blade, both mounted to the main wing in parallel to one another and having a first guide surface and a second guide surface facing towards each other, and a roller or slide pad mounted to the high lift body and guided between the first and second blades in engagement with at least one of the first guide surface and/or the second guide surface.

6. The wing according to claim 5 , wherein at least one of
at least one of the first blade or the second blade have a profile including a blade portion and a flange portion mounted to the high lift body or to the main wing, or
at least one of the first blade or the second blade is formed as or integrally formed with a rib of the main wing.

7. The wing according to claim 5 , wherein at least one contact plate is mounted to at least one of the first or second blades and includes at least one of the first or second guiding surfaces.

8. The wing according to claim 1 , wherein at least one of
the first stop element is mounted to or formed integrally with at least one of a first blade or a second blade, or
the second stop element is mounted to or formed integrally with a rib of the main wing.

9. The wing according to claim 8 ,
wherein at least one of
the first stop element includes a first stop flange formed at the lower or front end of at least one of the first or second blade and extending in the span direction, or
the second stop element includes a second stop flange formed at a rib of the main wing and extending in the span direction, or

wherein at least one of
the first stop element is formed as a chordwise extension of at least one of the first or second blade and is formed at the lower or front end of at least one of the first or second blade, or
wherein the second stop element is formed as a chordwise extending projection at a rib of the main wing, or

wherein at least one of
the first stop element is formed at the upper or rear end of at least one of the first or second blade, or
the second stop element is formed as at least one of a chordwise or spanwise extending projection at a rib of the main wing.

10. The wing according to claim 1 ,
wherein the additional support device comprises a deployment stop limiting deployment movement of the high lift body and thereby defining the deployed position of the high lift body, and
wherein the deployment stop comprises at least one lateral projection extending from at least one of a first guide surface or a second guide surface of at least one of a first blade or a second blade in the span direction and running against at least one roller or slide pad when the high lift body is in the deployed position.

11. The wing according to claim 1 , wherein the high lift body is formed as a droop nose,
wherein the first connection element is formed as a first rotation element mounted to the high lift body and mounted to the main wing rotatably about a first rotation axis, and
wherein the second connection element is formed as a second rotation element mounted to the high lift body and mounted to the main wing rotatably about a second rotation axis.

12. A leading edge high lift assembly for a wing according claim 1 , comprising
a high lift body, and
a connection assembly for connecting the high lift body to a main wing such that the high lift body is movable relative to the main wing between a stowed position and a deployed position,
wherein the connection assembly comprises a first connection element that is mounted to the high lift body and that is configured to be movably mounted to the main wing,
wherein the connection assembly comprises a second connection element that is mounted to the high lift body in a position spaced apart from the first connection element in a span direction, and that is co
