[Tunnel Specifications]  The 12 ft Pressure Wind Tunnel is a closed-return, variable-density, low-turbulence, subsonic wind tunnel. Customers can test models with four support systems with duplicates of these systems in two model preparation rooms to expedite model build up, check-out, and installation. The facility is used primarily for high Reynolds number testing, including the development of high-lift systems for commercial transports and military aircraft, high angle-of-attack testing of maneuvering aircraft, and high Reynolds number research.
