Abstract: A traction kite having a variable geometry leading edge that defines a high projected central propulsive region of increased surface area along the top portion of the kite, and lateral control regions of decreased surfaces area extending on opposite sides of the propulsive region. The leading edge thus defines a concave shape when viewed from the side while in flight. Providing a variable geometry leading edge maximizes propulsive forces due to increased surface area, while enhancing control and turning performance by minimizing the surface area of the control regions, namely those generally vertically disposed regions that begin at the tips and end at the propulsive region.

Abstract: A kite control system having a control bar adapted with an internal sheeting system that provides trim/sheeting control by adjustment of outer steering lines which are attached at or near the rear corners of the kite. A tubular control bar is adapted such that the outer steering lines are routed through the interior of the control bar through openings at each opposing end. The outer steering lines are each joined to a sheeting control line which extends back out one of the opposing ends in either a left hand actuated or right hand actuated embodiment. A fixed pin located approximately mid-length within the control bar provides a fixed structure about which one of the outer lines and/or sheeting control line is routed in U-turn fashion. By pulling the sheeting control line from the end of the control bar, the rider can shorten the effective length of the outer steering lines thereby increasing the angle of attack so as to power up the kite.

Abstract: A leading edge inflatable traction kite wherein the leading edge structure includes a plurality of spaced segments that are fabricated from a material with a higher elasticity, thus allowing for a greater amount of twisting and bending. The inflatable leading edge includes a series of elastically deformable segments disposed throughout the length thereof to facilitate selective torsional deformation of the leading edge and resulting overall angle of attack of the kite. These elastically deformable segments are preferably integrally formed as part of the leading edge support and are comprised of a material with a high elasticity, namely a higher elasticity than the remaining leading edge segments. Providing elastically deformable segments of high elasticity dispersed along the leading edge combined with regions of lower elasticity maximizes responsiveness and control by allowing leading edge deformation in response to user applied force, while the providing sufficient support to maintain kite stability.
