Abstract
Flying kites are disclosed including the bilaterally symmetric wind-bearing surfaces carried by a plain framework consisting of two triangular portions symmetric with respect to the central axis and pivotally interconnected along that axis. An arcuated resilient rod is fixed to those edges of the framework tilted at equal angles to the central axis. Several reinforcing rods may be disposed on the wind bearing surfaces symmetrically with respect to the central axis and across frame members forming the framework. Also an auxiliary wind including a triangular framework may be fixed to the wind bearing surfaces to be symmetric with respect to the central axis. The equations of motion of the present kite have been obtained and the strength of the framework has been discussed with the characteristics of the kite.
