Abstract
A free oscillation technique for obtaining the dynamic stability derivatives in yaw is applied to the pure yawing motion. The procedure of wind tunnel testing is to compute the derivatives after measuring deflecting angles of the model during the free oscillating motion. The charging compressed air is supplied for the initial excitation. The results of this experiment predicted feasible characteristics of the yawing motion, comparing with the data previously reported in the literature.
