High-speed Wind Tunnels
A 1936 NACA technical memorandum from the NASA Technical Reports Server, issued for aeronautical engineers and researchers, covering the design of high-speed wind tunnels. The pictures are black-and-white photographs and engineering drawings of compressor rotors, cooler elements, a steam turbine layout and a sectional view of a blower, giving a designer a clear sense of mid-century industrial machinery and technical plate layout.
