In 1950 Langley tested the drag characteristics of what was then the world's fastest submarine, the Albacore, in the 30 x 60 Full Scale Tunnel. Water and air are both essentially fluids of different densities. Air traveling at high speed can simulate water traveling at lower speed for many purposes. It was called the cave of the winds. For eight decades the Full-Scale Tunnel stood as a fixture of NASA's Langley Research Center in Virginia, its 30- by 60-foot test section used to try out every imaginable aircraft design, the Mercury spacecraft and even a submarine. Constructed in 1930 by the National Advisory Committee for Aeronautics (NACA) the wind tunnel was 434 feet long, 222 feet wide and 97 feet tall at its highest. Twin four-bladed wood propellers could move air through the entire volume at speeds up to 125 mph with the help of a 4, 000 horsepower electric motor. | |
