Wind Tunnel
The 80 by 120 foot wind tunnel at NASA Ames research center holds the distinction of being the largest wind tunnel test section in the world. This open circuit leg was added and a new fan drive system was installed in the 1980s. The 80 by 120 foot wind tunnel is used to support an active research program in aerodynamics, dynamics, model noise, and full-scale aircraft and their components. Each fan has a diameter equal to the height of a four-story building. The fans are powered by six 22,500 horsepower motors. Note the size of the fans relative to the 2 men standing in front. This wind tunnel is housed in this huge multi-roofed building at the NASA Ames research center, Mountain View, California. One of the tunnel’s air intakes is in the frame-like structure.
