Abstract:
An investigation was conducted at the von Karman Gas Dynamics Facility (VKF) of the Arnold Engineering Development Center (AEDC) 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 in this report with free decay motion measured on a free-oscillation gas bearing balance.
