Abstract
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.
Claims15
An improved stunt kite wing comprising an aerodynamic dihedral sail structure having a fabric sail tensioned on a supporting frame,
- said supporting frame comprised of opposing elongated lateral brace members along the leading edge of the wing and an elongated longitudinal brace member positioned beneath the lower surface of said wing intermediate the ends of the lateral brace members,
- first ends of said lateral brace members and a first end of said longitudinal brace member being attached to one another at a common terminus centrally positioned along the leading edge of the wing to define a fixed dihedral and sweep angle,
- the leading edge of said fabric sail being attached to both said lateral brace members and the trailing edge of said fabric sail being attached to a rearwardly disposed second end of said longitudinal brace member,
- said sail extending between laterally disposed second ends of said lateral brace members and said rearwardly disposed second end of said longitudinal brace member,
- opposing lateral spar members each attached to said lateral brace members at points intermediate said first and second ends of each said lateral brace members as well as to said longitudinal brace member at a common point,
- said common point of attachment to said longitudinal brace member being forwardly disposed of the points of attachment of said spar members to said lateral brace members,
- said lateral and longitudinal brace members being so attached to one another and said sail being so configured and caused to be tensioned over said brace members whereby a dihedral sail is formed, the lateral ends of which are positioned rearwardly from said common terminus and which sail assumes a tensioned or stressed condition along a portion of the leading edge of the wing intermediate the laterally disposed second ends of the lateral brace members such that the sail is spaced from the portion of the longitudinal brace member extending between said common terminus and said spar members.
