ABSTRACT:
A ram-air airfoil stunt kite has its upper forward edge provided with two stiffener members that provide a rounded leading edge and are connected together by a flexible joint. Two operator-held control strings are connected to bridles which are, in turn, connected to keels on the kite. The outboard bridle strings are shorter than the inboard bridle strings so as to remain taut during normal flying operations. When the apparent wind velocity increases, the kite becomes transversely curved, whereupon the inboard bridle strings become taut to establish an optimum maximum curvature.
