发明名称 Stunt kite dihedral wing
摘要 An improved stunt kite wing structure is provided comprising 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 together with connecting opposing lateral spar members. 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 such that the sail is spaced from the longitudinal brace member.
