Models of certain ICBM and IRBM nose-cone configurations have shown limit cycle yawing motions in low supersonic and high subsonic flight. For a given configuration the amplitudes of these limit cycles vary with Mach number, and possibly with Reynolds number. In general, the configurations exhibit limit cycles because of nonlinear damping moments, particularly in high subsonic flight. This paper presents the more interesting of these phenomena as observed by model firings in the free flight spark ranges of Ballistic Research Laboratories. These phenomena are correlated, when possible, with variations in flow phenomena. Author
