ABSTRACT:
The disclosed kite comprises two right-angled triangular frameworks symmetric with respect to a common side which forms a right angle with another side of each triangle. The triangular frames are pivotably interconnected through that common side, and a bilateral symmetric wind-bearing surface is carried by the frameworks. An arcuate resilient member connects the free ends of the other sides of the triangles to each other and has a spring constant greater than five times the weight of the kite divided by a distance between a point of attachment of a line to the kite and a point of attachment of the resilient member to one of the triangular frameworks and less than one half a tensile strength of the line attached to the kite.
