Abstract : Tests were conducted in the 50-in. Mach 10 wind tunnel of the von Karman Gas Dynamics Facility to determine the dynamic stability characteristics of a 10-deg half-angle cone at large amplitudes of oscillation. Support interference effects were also investigated. A free oscillation, high-amplitude (+ or - 35 deg) gas bearing balance supported by a transverse rod and yoke system was used. Data were obtained at a nominal Mach number of 10 at Reynolds numbers, based on the model base diameter, ranging from 0.46 to 1.84 x 10 to the 6th power. The dynamic and static stability data are compared with data obtained with a sting-supported model, range data, flow field theory, and conical flow theory. Selected test results are presented.
