A wing gap closure flap is positioned in an aircraft wing so that a gap between the wing structure and the leading edge of a landing flap can be closed during normal cruising positions of the landing flap and opened when the landing flap is in a starting position or in a landing position. The gap is formed on the underside of the aircraft wing and the gap closure flap is operated by a positioning shaft which itself is driven through a drive lever linkage by the drive shaft for the landing flap. The wing gap closure flap is connected through a lever mechanism to the positioning shaft which is preferably divided into shaft sections where a plurality of wing gap closure flaps are used. Each shaft section is driven by the landing flap drive shaft. A defined motion of the wing gap closure flap or flaps is achieved in that the positioning of the wing gap closure flaps is synchronized in a limited angular range with the positioning of the landing flap by the cooperation of the respective drive mechanisms.

An apparatus for controlling a wing gap in an aircraft wing having landing flaps (3) forming said wing gap, comprising at least one wing gap closure flap (1), at least one rotational positioning shaft (4) for operating said wing gap closure flap (1), bearings rotatably mounting said positioning shaft (4) in said aircraft wing, at least one lever mechanism (5) operatively connecting said positioning shaft (4) with said wing gap closure flap (1), at least one landing flap drive (7) and a drive coupling for transmitting power from said landing flap drive to said positioning shaft (4) for operating said at least one wing gap closure flap (1), wherein said positioning shaft (4) comprises a first hollow shaft section and a second hollow shaft section extending inside said first hollow shaft section and a torsion spring (20) inside said second hollow shaft section, said torsion spring (20) coupling said first and second hollow shaft sections to each other, for permitting a transfer of drive power from one hollow shaft section to the other and for permitting a limited continued rotation of one shaft section relative to the other shaft section when one shaft section is stopped, whereby in end positions of said wing gap closure flap (1) further rotation of one of said shaft sections is taken up by said torsion spring but not transmitted to said wing gap closure flap (1).
