Abstract
Free-flight tests of flat plates and prisms were made in a wind tunnel to know the characteristics of dispersion of wind-borne missiles. In these tests, the models were released into a flow from rest and then caught by a net spread perpendicular to the flow. The positions on the net were recorded by a video camera. In this paper, probability distributions of the lift coefficient, which represents the magnitude of the aerodynamic force which disperses the models vertically, are calculated from the test results by using equations of motion of a two-dimensional model. The characteristics of the distributions and their relations with nondimensional parameters are discussed.
