Fuel Consumption of a Carburetor Engine at Various Speeds and Torques
This is a 1938 NACA technical note from the National Advisory Committee for Aeronautics, issued as an engineering report on carburetor engine fuel consumption across speeds and torques, aimed at aircraft engineers and researchers. The three plates show a rotated photograph of a single-cylinder air-cooled engine test set-up with dynamometer and gauges, a line-drawn schematic of the test rig with orifice tank, air blower, surge tank and air cooler, and paired front and rear photographs of Wright and Pratt and Whitney radial engine cylinders. A designer could take the stark grey industrial photography, the cylinder fin patterns and the clean technical diagram linework as references for mechanical and engineering themes.
