Stability Derivatives of a 10 degree Cone Executing Planar and Nonplanar Motion at Mach 14.
Abstract
A 10 degree half angle circular cone with 1.6% nose bluntness was mounted to the sting-strut support system of ARL's 20-inch Mach 14 wind tunnel by means of a two-degree of freedom flexure. The small amplitude (approximately 3 deg.) free oscillation technique allowed the investigation of planar motion in pitch, or planar motion in yaw, or nonplanar motion in pitch and yaw combined. In the case of planar motion, the logarithmic amplitude decayed linearly with time. In the case of nonplanar motion, however, the amplitude decay of both the pitch and yaw components was modulated.
