  • Patent number: 4911384
    Abstract: A winged kite (10) comprises an elongated body (12) attached on a bottom side of a flat sheet lift member (14) forming right and left wings (44, 46) and a diverging flat tail (48). An elongated flexible spar extends between respective outer end portions (60, 62) of the right and left wings across the top side of the lift member and a support ring (68) attached to the top side of the lift member at the body supports the body and the lift member from the spar. Leading edge salient portions (70, 72) of the wings curl upwardly about the spar, the amount of curl being substantially affected by wind striking the right and left leading edge salient portions during flight of the kite. A tether is attached only near the front end of the body. The lift member is formed of a main body sheet (40), for forming the wings and tail, and a support sheet (42), which extneds along the tail between the wings to a front end portion of the body.

  • Patent number: 4846424
    Abstract: A ram-air airfoil stunt kite has its upper forward edge provided with two stiffener members that provide a rounded leading edge and are connected together by a flexible joint. Two operator-held control strings are connected to bridles which are, in turn, connected to keels on the kite. The outboard bridle strings are shorter than the inboard bridle strings so as to remain taut during normal flying operations. When the apparent wind velocity increases, the kite becomes transversely curved, whereupon the inboard bridle strings become taut to establish an optimum maximum curvature.
