ABSTRACT:
An improved wing structure is provided having a self-induced camber. The wing comprises an aerodynamic dihedral sail structure having a fabric sail tensioned on a supporting frame comprised of lateral brace members and a longitudinal member intermediate the ends of the lateral braces. The tensioning of the sail and the configuration of the supporting frame is such that the sail assumes a dihedral shape, with the sail being caused to assume a tensioned or stressed condition along a portion of the leading edge of the sail intermediate the respective lateral ends of the sail resulting in the formation of a self-induced camber at that location.
