The Transonic Wind Tunnel
and the NACA Technical Culture
The Transonic Wind Tunnel and the NACA Technical Culture

The 1951 Collier Trophy recognized a transonic-research-technology advance first applied in the two NACA Langley wind tunnels shown in these midcentury views.15 Top: Air flows counterclockwise in the 16-Foot Transonic Tunnel, passing repeatedly through the test section linked to the topmost floors of the facility's brick office building. Bottom: In the 8-Foot High-Speed Tunnel's similar circut, a concrete igloo enclosed the test section. (NASA photos L-90-3752 and NACA 12000.1).

In fact, given the wind tunnel component in the NACA's overall contributions, a Collier Trophy for an NACA tunnel seems fitting, as three low-subsonic examples from the 1920s and early 1930s illustrate. Each was the first of its kind in the world, and was soon copied elsewhere
