Portion of the Unitary Plan Wind Tunnel in 2014. Construction of this facility began in 1950-1951 and continued until 1955. Because no one wind tunnel could meet all the demands for additional research facilities simulating the entire range of aircraft and missile flight, NACA chose to build the Ames tunnel with three separate test sections drawing power from a common centralized power plant.
Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over 100 feet (30 m), and with air speeds from a light breeze to hypersonic.
Results of wind tunnel tests of these models are generally published in the form of nondimensional aerodynamic coefficients (thus being made independent of model size) and made available to the wind-tunnel community, often in review reports containing inter-facility comparisons of data, [5] [8] [9] [10] discussing observed scatter of results ...
The El Segundo Trisonic Wind Tunnel or North American Trisonic Wind Tunnel (NATWT) was a wind tunnel that was located in El Segundo, California. [8] It was built by North American Aviation in the 1950s. The tunnel had a maximum testing speed of Mach 3.5. The NATWT was a blow-down type tunnel.

The Mars Science Laboratory landing parachute under test in the 80 by 120-foot wind tunnel. Note the people in the lower-right corner of the image. The 40 by 80 foot wind tunnel circuit was originally constructed in the 1940s and is now capable of providing test velocities up to 300 knots (560 km/h; 350 mph). [26]
The Hypervelocity Wind Tunnel 9 is located in Silver Spring, Maryland; The National Full-Scale Aerodynamics Complex (NFAC) is located at NASA Ames Research Center, Moffett Field, California. The NFAC was closed by NASA in 2003.
