National Full-Scale Tunnel Aerodynamics Complex

This aerial view shows the 40 x 80 Full-Scale Tunnel towering over the 6- by 6-Foot Supersonic Tunnel (R) and the 16-Foot High-Speed Tunnel (lower R). The tunnel’s external steel framework and asbestos-cement walls are readily evident. The central structure with no external structure houses the test section. The non-rectangular contraction, diffuser, and fan sections were fabricated entirely of steel.
