Abstract
An aircraft wing includes a leading element; a trailing element positioned behind the leading element relative to a direction of movement of the aircraft and an actuation system for moving one of the elements between a retracted position and an extended position in which there is an air gap between a lower surface of the leading element and a surface of the trailing element. Two or more elongate stiffening ridges extend downwards from the lower surface of the leading element, and each adjacent pair of ridges is separated by a channel. The leading element is shaped to provide an improved air gap, preferably one which is parallel or convergent in all positions. Typically the volume of at least one of the ridges is less than the 50% of the volume of a channel defined by that ridge.
