A high lift system is provided for an aircraft. The high lift system includes, but is not limited to a lift flap arranged on a wing and coupled to the wing so as to be movable relative to the wing, between a retracted position and at least one extended position. In the retracted position the lift flap rests against the wing, and in an extended position forms an air gap to the wing. The lift flap directed towards its trailing edge comprises at least one region of variable curvature, which region in an extended position of the lift flap extends towards the wing.

1. A high lift system for an aircraft, comprising: a wing;a lift flap arranged on the wing and coupled to the wing so as to be movable relative to the wing, between a retracted position and at least one extended position, in the retracted position the lift flap is configured to rest against the wing
1. A high lift system for an aircraft, comprising: a wing;a lift flap arranged on the wing and coupled to the wing so as to be movable relative to the wing, between a retracted position and at least one extended position, in the retracted position the lift flap is configured to rest against the wing, and in an extended position the lift flap is configured to form an air gap relative to the wing; andat least one region of the lift flap that includes at least one of a flexible material and a pivotable trailing edge that produces a variable curvature towards the trailing edge, which in the extended position of the lift flap extends towards the wing. 2. The high lift system of claim 1, wherein the lift flap in the extended position is offset upstream to a leading edge of the wing that comprises a curved profile. 3. The high lift system of claim 1, wherein the lift flap is configured to assume at least one first shape of curvature and a second shape of curvature. 4. The high lift system of claim 1, wherein the air gap extends between the trailing edge of the lift flap that is in the extended position and a surface of the wing which when assuming a first shape of curvature is convergent downstream. 5. The high lift system of claim 1, wherein the lift flap in a first shape of curvature is pre-formed. 6. The high lift system of claim 1, wherein the lift flap is at least partially formed of a fiber composite material. 7. The high lift system of claim 1, wherein the pivotable trailing edge is movable by way of an adjustment element, and the lift flap is adjustable by moving the pivotable trailing edge to a first shape of curvature and to a second shape of curvature. 8. The high lift system of claim 7, wherein the adjustment element is passive. 9. The high lift system of claim 7, wherein the adjustment element is an active actuator. 10. The high lift system of claim 7, wherein the pivotable trailing edge is a separate and pivotably held component. 11. The high lift system of claim 1, wherein the wing comprises a receiving surface against which the lift flap is pressed to assume a second shape of curvature. 12. The high lift system of claim 11, wherein the receiving surface comprises a receiving-surface protection device. 13. A method for moving a lift flap, comprising: moving the lift flap from a retracted position on a wing to an extended position, the lift flap including at least one region having at least one of a flexible material and a pivotable trailing edge that produces a variable curvature towards the trailing edge; andchanging a curvature of the at least one region of the lift flap to a first shape of curvature. 14. The method of claim 13, further comprising: moving the lift flap to the retracted position towards the wing; andchanging the curvature of the at least one region to a second shape of curvature. 15. An aircraft, comprising: two wings; andat least one high lift system, including:a lift flap arranged on a wing and coupled to the wing so as to be movable relative to the wing, between a retracted position and at least one extended position, in the retracted position the lift flap is configured to rest against the wing, and in an extended position the lift flap is configured to form an air gap relative to the wing,wherein the lift flap towards its trailing edge comprises at least one region that includes at least one of a flexible material and a pivotable trailing edge that produces a variable curvature, which in the extended position of the lift flap extends towards the wing. 16. The aircraft of claim 15, wherein the lift flap in the extended position is offset upstream to a leading edge of the wing that comprises a curved profile. 17. The aircraft of claim 15, wherein the lift flap is configured to assume at least one first shape of curvature and a second shape of curvature. 18. The aircraft of claim 15, wherein the air gap extends between the trailing edge of the lift flap that is in the extended position and a surface of the wing which when assuming a first shape of curvature is convergent downstream. 19. The aircraft of claim 15, wherein the lift flap is at least partially formed of a fiber composite material. 20. The high lift system of claim 1, wherein the air gap relative to the wing is devoid of a divergent region.
