A very light wing, configured like a spherical segment, is intended to be used in the traction and lift of various loads. The wing includes a leading edge and a trailing edge and an inflatable armature covered by a flexible envelope. The surfaces of the wing are configured in the shape of an aircraft wing profile and the edges of the wing curve in two planes. The leading and trailing edges of the wing are oriented to intersect near the tips of the wing, and each of the tips of the wing receives a control rope via an adjusting plate. The control rope is passed through a pulley mounted on a craft to be displaced by a person through a harness. The wing can be used in sliding sports, yachting and gliding.

In a propulsive wing of an aerodynamic profile linked by control ropes to a load, the wing including a thin flexible envelope and having a top surface and a bottom surface and an inflatable armature made up of a first strut and second struts, the first strut extending along a leading edge of the wing and having a thickness dimension that varies according to location along the wing leading edge whereby the first sturt has a thickness at its extremities that is less than the thickness of the first sturt near the middle section thereof, the wing having a tailing edge, the first strut extremities forming tips, the improvement in combination therewith comprising: the leading and trailing edges of the wing being oriented to intersect each other near the first strut tips and the wing having an arcuate shape between the tips to form a lune-like spehrical segment which curves in two planes from one of the tips through the middle section of the first sturt to the other of the tips with each tip being adapted to receive a control rope with only two control ropes being required by the wing, the improvement further comprising the variation of the first strut thickness dimension defining a crescent shape for the wing dimension between the top and the bottom surfaces of that wing.
