An investigation was made to determine if the quasi-steady-state values of aerodynamic forces and moments normally measured in a wind tunnel can be used for the analysis of vehicle stability and handling under wind gust conditions. A new experimental test technique was developed whereby a 1/10 scale model could be catapulted throw the test section of a low turbulence wind tunnel, per pendicular to the tunnel airflow, thus simulating a gust condition. By varying the model speed and the tunnel speed, a wide range of relative wind or yaw angles could be simulated.
