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. In one embodiment, the body is formed by a single sheet folded on itself with a fold area being attached to the bottom side of the lift member between the wings and the tail.
