In 1934 the world's largest wind tunnel was constructed at Langley Field with a 30-by-60-foot (9.1 m × 18.3 m) test section; it was large enough to test full-scale aircraft. [9] [10] It remained the world's largest wind tunnel until the 1940s, when a 40-by-80-foot (12 m × 24 m) tunnel was built at NASA's Ames Research Center in California. [11]
The Full-Scale Tunnel [4] (abbreviated FST, also known as the 30-by 60-Foot Tunnel [5]) was a wind tunnel at NASA's Langley Research Center. It was a National Historic Landmark . In 1929, National Advisory Committee for Aeronautics began construction of the world's first full-scale wind tunnel, where high-performance airplane would be tested.
The cross section of the tunnel is 8.2 feet (2.5 m) high and 8.2 feet (2.5 m) wide. Unlike full-scale wind tunnels, the NTF can adjust airflow to match any model size down to 1/50 scale. The facility can operate at temperatures ranging from -250 ° F to + 150 ° F. [ 1 ] To achieve lower than ambient temperature, liquid nitrogen is sprayed into ...
The wind tunnel will be 130 feet tall, Fremaux said, comparing its capabilities to those it will replace: The 12-foot, Low-Speed Spin Tunnel built in 1939 and the 20-foot, Vertical Spin Tunnel ...
It was the first of many now-famous NACA and NASA wind tunnels. Although this specific wind tunnel was not unique or advanced, it enabled NACA engineers and scientists to develop and test new and advanced concepts in aerodynamics and to improve future wind tunnel design. Atmospheric 5-ft wind tunnel (1920) Variable Density Tunnel (1922 ...
The tunnel was deactivated in 1956, when a new 8-foot (2.4 m) tunnel was built near it. The wind tunnel was used for critical tests that validated the area rule for the design of supersonic aircraft. This said that the fuselage of the aircraft should narrow at the wings and expand at their trailing edges. This resulted in "wasp-waisted" aircraft.
