Abstract: The modular foil includes a wing and a fuselage extending in a longitudinal direction and bearing the wing. The fuselage includes a central segment, a first segment bearing a first portion of the wing, and being removable from the central segment, and an assembling device to connect the central segment with the first segment in the longitudinal direction. The central segment and the first segment are connected end to end. The assembling device includes a pair formed by a male connector and a female connector cooperating through a specific interlocking. The male connector includes at least one outer inclined wall, complementary and cooperating with an internal inclined wall born by the female connector for an optimal interlocking between the central segment and the first segment. There is a locking device along the longitudinal axis of the fuselage ensuring locking in at least one direction of the longitudinal axis.

Abstract: Inflatable fraction kite (1) and the system for managing the traction power, the direction and the transient maneuvers thereof, shaped as a negative dihedron, of the type known as ‘C-shape’ or ‘C-kite’, and comprising load-bearing riggers and riggers used to manage the direction and trim, the kite (1) being characterized in that in flight it is designed to be delta-shaped and for this reason its leading edge (10), when laid flat, has a curvature such that, for each half-wing (12, 13) of the kite, the angle (?) formed by the tangent (S) to said central point (A) and the tangent (T) at a given point (B) increases as said given point (B) moves from the forward central point (A) toward the end (14, 15) of the kite (1) and in that, in the first third of said half-wing (12, 13) of the kite, from the forward central point (A) and in the direction of one end (14, 15), said angle (?) is greater than 15°.
