Patent ID: 8191835

Claim:
A wing for an aircraft, having: a mainplane having an upper face, a lower face, and a nose area facing a flow, an additional airfoil, articulated on the mainplane, having a nose area facing the flow and a rear-face area facing the nose area of the mainplane, and being movable between a retracted state and an extended state with a slot between the nose area of the mainplane and the rear-face area of the additional airfoil being varied, and a slot-varying apparatus arranged on a lower face of the additional airfoil, running along a contour of the additional airfoil when the additional airfoil is in the extended state, and at least partially covering a slot area between the mainplane and the lower face of the additional airfoil when the additional airfoil is in the retracted state, wherein the slot-varying apparatus is arranged at a transition between the nose area and the rear-face area of the additional airfoil and can be varied between a curved configuration, the slot-varying apparatus, when the additional airfoil is in the extended state, forming a curved part of an aerodynamic profile of the additional airfoil in the curved configuration, the transition from the nose area to the rear-face area of the additional airfoil being curved at the curved part, and an extended configuration, the slot-varying apparatus, when the additional airfoil is in the retracted state, at least partially covering the slot area in the extended configuration, wherein the slot-varying apparatus is designed to be elastically flexible at least in places in a profile chord direction of the wing, or has flexibly variable curvature, wherein the slot-varying apparatus can be varied between the curved configuration and the extended configuration via a drive device coupled to the slot-varying apparatus; and wherein the drive device is arranged in the slot-varying apparatus.
