Popis:	An investigation was conducted to evaluate the validity of the small-amplitude oscillation test technique for obtaining pitch-damping data. The effects of model oscillation frequency, oscillation amplitude, and sting length on pitch-damping characteristics were investigated for several configurations. Also, the pitch-damping data obtained by the small-amplitude forced-oscillation method were used in a six-degree -of-freedom computer program to predict decay motion from large amplitudes. These computed angular motions are compared with free decay motion measured on a free-oscillation gas bearing balance. The investigation was conducted at Mach number 3 and at a Reynolds number per ft of 4.73 x 10.
