National Full Scale Aerodynamic Complex: Operated by the U.S. Air Force. The 40-by 80-foot wind tunnel circuit is capable of providing test velocities up to 300 knots. The 80-by 120-foot test section is the world's largest wind tunnel and is capable of velocities up to 100 knots.
7-by 10-foot Wind Tunnel: Closed circuit wind tunnel operated by the U.S. Army. The constant cross-section test section measures 7 feet high by 10 feet wide by 15 feet long. The tunnel has a maximum speed of approximately 355 ft/s.
Closed-return, variable-density tunnel with a fixed-geometry, ventilated test section with a flexible wall nozzle with a Mach range of 0.20 to 1.45.
Closed circuit, single return, variable density, continuous flow wind tunnel with a Mach range of 1.55 to 2.55.
