Tests were conducted in the 30-Inch Hypersonic Tunnel on the Aerospace Research Laboratories, Wright-Patterson Air Force Base, Ohio to determine the effects of Reynolds number and frequency of oscillation on the damping-in-pitch derivatives of a 10-deg half-angle cone. Free oscillation data were obtained at a nominal Mach number of 20, at Reynolds numbers, based on model base diameter, from 50,000 to 100,000, and at model oscillation frequencies from 8 to 45 cps. Test results are presented, and comparisons are made with modified Newtonian impact theory and an unsteady flow field theory.
