ABSTRACT:
A kite having separate forward and aft sails, each arched about a common longitudinal kite axis and each sail disposed concave downward in flight. The concave shape of the sail funnels the wind through the kite. Lift is derived from the central portions of the sail while the lateral portions of the sail, which are nearly vertical and are parallel to the wind direction, provide lateral stability. The proportional lift and weight balance provided by the aft sail, in combination with the bridle arrangement, provide longitudinal stability.
