Wind-tunnel Tests of Carburetor-intake Rams
A 1938 NACA Technical Note, issued by the National Advisory Committee for Aeronautics as a government engineering report, documenting wind-tunnel tests of carburetor-intake ram designs for aircraft engines. The single photographic plate, Figure 3, shows a constant-area external ram mounted on the cowling of a radial air-cooled engine inside a test facility. For a designer, it offers a plain, measured view of a streamlined intake fixed to an engine nacelle, useful for mechanical or industrial reference.
