The NASA Ames Research Center at
Moffett Field contains the largest wind tunnel in the World.
Excerpted from the American Society of Mechanical Engineers web site:
This wind tunnel complex was developed by the National Advisory Committee for Aeronautics (NASA's predecessor) to serve the emerging need for supersonic research and development following World War II. The three-testing-section configuration covers Mach number .03-3.5 and utilizes a single common drive and two compressors.
The Ames Unitary Plan Wind Tunnel has contributed to the America's preeminence in the jet age both in commercial and military aviation testing models from the Douglas DC-8 to commercial transports that will be flying in the near future. These tests include cruise performance, lateral and longitudinal stability, structural loads, and aeroelastic and dynamic load measurements.
The 8-by-8 foot segment of the tunnel opened for operation in 1956, it began construction in 1950 as a result of the Unitary Wind Tunnel Plan Act of 1949 passed by the United States Congress. The Ames facility played a heavy role in the United States space program performing aerodynamic testing on the Mercury, Gemini, and Apollo spacecrafts and the space shuttle. Today the tunnel is contributing to maintaining excellence in aeronautics testing configurations of the High Speed Civil Transport, Advanced Subsonic Transport, as well as military configurations.
