An Examination of the Small-Amplitude Dynamic Stability Test Technique.
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.
