Rolling Wind Tunnel

An example of a rolling wind tunnel. The moving ground plane enables the road and air speed to be matched, which accurately simulates the relative motion of car, air and track. The model is suspended from a three-component balance which allows measurements of the aerodynamic forces acting on the car. The operation of the wind tunnel includes the setting of air and ground velocities to measure lift, down-force and drag. In this example the model is a quarter scale and the wind tunnels dimesions are 4.5 X 4 ft.
