Abstract

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.
