The Effect of Fuel Consumption on Cylinder Temperatures and Performance of a Cowled Wright J-5 Engine
This is a 1929 NACA technical report, published by the National Advisory Committee for Aeronautics, on how fuel consumption affected cylinder and spark-plug temperatures in a cowled Wright J-5 aircraft engine, written for engine engineers. Its pictures are engineering charts of temperature curves plotted against fuel and mixture settings, polar diagrams of temperatures around cylinder barrels, and black-and-white photographs of a cowling and its fittings. A designer could take the clean grey-line graph style, dense radial diagrams, and the mechanical photographs of cooling fins and cowl rings as visual references for technical schematics.
