Arnold AFB in Tullahoma, TN contains a Propulsion Wind Tunnel Facility, complete with three wind tunnels. Two of the wind tunnels are 16-foot tunnels (one transonic and one supersonic), and one 4-foot tunnel (transonic). Inside of these wind tunnels is where the testing of large-scale aircraft models occurs.
