Patent ID: 8919701

Claim:
An inflatable traction kite and system for managing the traction power, the direction, and the transient maneuvers of said kite, comprising: a wing having: a leading edge which intersects a line (L) separating the kite into two opposite half-wings at a forward central point (A), and the leading edge has, when laid flat, a curvature such that, for each of the half-wings of the kite, an angle (α) formed by the tangent (S) to said forward central point (A) with the tangent (T) at a given point (B) is increasing when said given point (B) moves from the forward central point (A) to a respective end of the kite along the leading edge, wherein, in the first one-third of each of said half-wings of the kite, from the forward central point (A) to the respective end, said angle (α) is larger than 15° , and a trailing edge which includes, when laid flat, a forward sweep of the trailing edge at each lateral extremity portions of the kite; bearing riggers, comprising ramifications, connected to the leading edge of the kite in a median portion of the kite; and control riggers connected to the lateral extremity portions of the kite, external to said median portion, said control riggers being used for managing the direction and the trim, wherein the kite has, during flight, an arch shape with a ratio between a flat wing span and an in-flight wing span larger than 1.5, and wherein the kite has approximately a delta shape during flight.
