Wind tunnel helps determine impact of hypersonic speeds
Steven Schneider, an aerospace engineer and professor in Purdue's School of Aeronautics and Astronautics, operates the university's one-of-a-kind wind tunnel, which runs quietly at Mach 6, or six times the speed of sound. Researchers will use the $1 million wind tunnel to help design advanced aircraft that travel at hypersonic speeds, or faster than Mach 5, which is about 4,000 mph at sea level. (Courtesy photo)
