A resin model and diagram of the North American Aviation (NAA) Trisonic Wind Tunnel (TWT), El Segundo, California.

The Trisonic Wind Tunnel was built by North American Aviation in the 1950's. The tunnel was so named because it was capable of testing in three speed regimes – subsonic, transonic, and supersonic, with a maximum speed of Mach 3.5.

Aircraft such as the XB-70 Valkyrie, B-1 Lancer, X-15 space plane, Apollo Command and Service Module, the second stage of the Saturn V rocket, and the Space Shuttle orbiter were all designed by North American Aviation.

The last test to be conducted at TWT was completed on August 28, 2007. In 2009 the TWT was demolished.
