The world's largest wind tunnel, Ames Aeronautical Laboratory, Moffett Field, California, USA, 1947. 40 x 80 foot wind tunnel which, when built, was the world's largest. The camera is stationed in the tunnel's largest section, 173 feet wide by 132 feet high. Here at top speed the air, driven by six 40 foot fans, is moving about 35 to 40 miles per hour. The rapid contraction of the throat (or nozzle) speeds up this air flow to more than 250 miles per hour in the oval test section, which is 80 feet wide and 40 feet high. The tunnel encloses 900 tons of air, 40 tons of which rush through the throat per second at maximum speed. The experimental model seen here is almost 50 feet long. Embodying a sharply swept-back wing suitable for supersonic flight, it is undergoing tests designed to improve the landing characteristics of this type of airfoil. Mounted on struts connected to scales under the test section, it is "flown standing still" while each element such as lift and drag is measured and air pressures occurring across the wing are recorded. Information gathered from such tests were made available to the nation's aircraft manufacturers by the National Advisory Committee for Aeronautics (now NASA).
