This propulsion wind tunnel (PWT) at Arnold AFB was the first large-scale facility for testing jet and rocket engines in simulated high-speed flight conditions. It has a unique combination of transonic (1955) and supersonic (1960) wind tunnels using a common 236,000 horsepower drive, the world's largest when built. It can achieve air speeds up to Mach 4.75 at altitudes up to 150,000 feet in its 16-foot square, removable test sections. Design engineers were Lief J. Sverdrup, John R. Parcel, Brice Smith, and Walter Cook, of Sverdrup and Parcel, St.
