Abstract

A high lift system for an aircraft includes: a main wing, a flap disposed on the main wing of the aircraft that can be adjusted between a retracted position and several extended positions relative to the main wing by means of flap actuating means and a drive device, said system further comprising a carrier part disposed on the main wing to which the flap actuating means are coupled and relative to which the flap actuating means for adjusting the flap can be moved, wherein the carrier part is disposed on the main wing by means of a bearing device comprising an adjusting device with which the orientation of the carrier part relative to the orientation of the main wing can be adjusted.

Claims

1. A high lift system for an aircraft, comprising:

a main wing,

a flap that is arranged on the main wing of the aircraft and is adjustable relative to the main wing between a retracted position and several extended positions by means of flap actuating elements and a drive device,

a carrier part arranged on the main wing, to which the flap actuating elements are coupled and relative to which the flap actuating elements are movable in order to adjust the flap wherein,

the carrier part is arranged on the main wing with the aid of a bearing device that features an adjusting device comprising a first adjusting device and a second adjusting device which have a distance from each other along a flow direction, by means of which an orientation of the carrier part is adjustable relative to an orientation of the main wing,

at least one of the adjusting devices includes a distance adjusting device, by means of which a distance of an upper side of the carrier part on the distance adjusting device from a wing chord of the main wing is adjustable and which comprises;

a screw connection with a receptacle device on a side of the carrier part and a receptacle device on a side of the main wing, a connecting element for connecting the receptacle devices, as well as a spacer for adjusting a distance of the upper side of the carrier part on the distance adjusting device from the wing chord of the main wing and thereby the orientation of the carrier part relative to the orientation of the main wing.

3. The high lift system according to claim 1, wherein the first adjusting device includes a joint for producing an articulated connection between the main wing and the carrier part and the second adjusting device includes a distance adjusting device.

5. The high lift system according to claim 1, wherein the first adjusting device is positioned upstream of the second adjusting device.

6. The high lift system according to claim 1, wherein the first adjusting device is in the form of an articulated bolt connection with a pin on the side of the wing that is rigidly connected to the main wing, a receptacle device on the carrier part and an axle that connects the receptacle device and the pin in an articulated fashion.

7. The high lift system according to claim 1, wherein the carrier part is arranged underneath the wing such that it is aligned in the flow direction and provided with a rail-like guiding device, on which a slide coupled to the flap is movably guided.

8. The high lift system according to claim 7, wherein the connection between the slide and the flap includes a rigid connection and the slide is adjustable by means of a spindle drive or a lever drive.

9. The high lift system according to claim 8, wherein the flap is supported on the carriage by means of an articulated connection that extends angular or transverse to the main flow direction.

10. The high lift system according to claim 9, wherein the drive device features a rotary drive driving motor and an output lever that is coupled to the driving motor and to a connecting piece fixed on the flap.

11. The high lift system according to claim 1, wherein the flap is adjustable by means of a lever adjusting device.

12. The high lift system according to claim 1, wherein:

the lever adjusting device includes two connecting pieces that are connected to the main wing, a carrier part and an additional connecting piece, both of which are arranged on the main wing,

the carrier part is arranged underneath the connecting piece,

a lever is pivotable in an articulated fashion and is coupled to the upper connecting piece by means of a pivot joint arranged thereon and a lever of respectively suitable length that can be pivoted in an articulated fashion is coupled to the carrier part by means of an additional pivot joint arranged thereon,

the lever coupled to the upper connecting piece is connected to a flap connecting piece and the lever coupled to the carrier part is connected to a flap connecting piece, and

both flap connecting pieces are arranged on the flap.

13. The high lift system according to claim 11, wherein at least one spoiler is also movably coupled to the main wing.

14. The high lift system according to claim 13, further comprising a motive coupling provided between the spoiler and the flap.

15. The high lift system according to claim 14, wherein the motive coupling between the spoiler and the flap is realized mechanically or with a control or regulating system.
