LANGLEY AIR FORCE BASE, Va. – Whit Seay, an Old Dominion University engineer, monitors an X-48C experimental aircraft mounted in a full-scale wind tunnel here Sept. 1. ODU operates the tunnel, which was built in 1930, for clients including NASA, Boeing Co. and the U.S. Air Force. The tunnel measures 30x60 feet and is the largest university operated wind tunnel in the world. The tunnel provides a controlled test environment to measure aerodynamic forces on vehicles. ODU will cease wind tunnel testing on Sept. 4, and NASA's Langley Research Center will later dismantle the building because it is no longer strategically important to NASA’s aeronautical research.
