NACA-Lewis 10ft x 10ft Unitary Supersonic Wind Tunnel. The Unitary Wind Tunnel Plan Act of Congress, a post-war act, stipulated that NACA wind tunnels were to be made available to industry for testing. This push was to encourage the improvement of existing aircraft engines. This aerial view shows the size of the facility. The Lewis Center is now known as the John H. Glenn Research Center.
Looking down the throat of the world's larget tunnel. The scene is NACA's 40 x 80 foot wind tunnel at Ames Aeronautical Laboratory, Moffett Field, California. The camera is stationed in the tunnel's largest section, 173 feet wide by 132 feet high.
Hyper X mounted on Pegasus booster rocket in 20 Inch Mach 6 Wind Tunnel. The Hyper X is an unmanned hypersonic research aircraft launched atop an air launched Pegasus rocket and capable of reaching speeds of Mach 10.
In September of 1959, JPL held a press conference to celebrate the opening of its new $3,500,000 hypersonic wind tunnel, the third wind tunnel built at JPL from 1947 to 1959. A JPL engineer is shown positioning a scale model of a missile in the tunnel's 21 x 21 inch test section.
Aerial view of the NASA Ames Research Center, Mountain View, California. The large flaired rectangular structure in the center of the photo is the 80 x 120 Foot Full Scale Wind Tunnel. Adjacent to it is the 40 x 80 Foot Full Scale Wind Tunnel which has been designated a National Historic Landmark.
