Historic Photos of NASA's Cavernous Wind Tunnels

Throughout the 20th century, NASA (and its predecessor, NACA) made extensive use of wind tunnels to test and refine designs for airplanes, spacecraft, and many other vehicles and structures. Dozens of specialized tunnels were constructed over the years at Langley Research Center in Virginia and Ames Research Center in California, to test the effects of high windspeed, turbulence, icing, ionization, and much more. Some of these facilities were gigantic—the largest, still in operation, is the 80-foot by 120-foot tunnel at NASA's Ames Research Center. In the 1990s, a surplus of government wind tunnels and advances in computer simulations led to a consolidation, and a number of older facilities were demolished. Gathered here, a collection of images of NASA’s amazing wind tunnels from the past century.
