### Wind tunnel

In 1931, the first U.S. full scale wind tunnel for testing airplanes was opened in Langley Field Research Center, Va. In the 30-ft high by 60-ft wide tunnel, flying characteristics of full-size airplanes were tested in air speeds up to 115-mph. The air was driven by two propellers downstream, each over 35-ft in diameter, powered by 4,000 hp electric motors. Over the next 65 years, tests were also run on helicopters, the Mercury space capsule, parachutes and parafoils, the occasional dirigible and, once, the fastest submarine in the world. Generations of aircraft passed through the Full-Scale Tunnel; all emerged more airworthy than when they entered. NASA closed the tunnel in October 1995. A smaller scale wind tunnel opened there in the 1920s. By 1936, a new wind tunnel was built able to provide an air speed of 600 mph.[Image: A scale model of an airship under test.]
