DYNAMIC STABILITY MEASUREMENTS
Abstract
The dynamic and static stability of a nonspinning missile in a wind tunnel is considered. It is assumed that the method used is to mount the model so that it is free to oscillate, and to observe the time rate of decay of oscillations with and without the wind on. Some of the sources of error are discussed. It is assumed that the test is to study the dynamic stability of a non-spinning missile when flying at supersonic speeds. The time history of decaying oscillations is recorded both with wind on, and with wind off (generally with the tunnel evacuated). From these observations, it is hoped that the aerodynamic damping which would occur in free flight can be estimated.
