When driving through the main gate at Moffett Field in Mountain View, California, you are greeted by the sight of the 1/3 scale space shuttle wind tunnel model. During the 1970s, she underwent more than 200 hours of subsonic testing in the 40 by 80 foot wind tunnel at NASA Ames Research Center. When the tunnel was built in 1941, it was the largest in the world, now second only to the 80 by 120 foot wind tunnel now grafted onto the side of the original.
In the days before computational fluid dynamics, testing this scale model was the best way to verify that the orbiter would fly true during the all important landing phase of the mission. These physical models are still often used today to verify that computer models are analyzed correctly.
