Cooling on the Front of an Air-cooled Engine Cylinder in a Conventional Engine Cowling
A 1939 NASA technical report on cooling for air-cooled aircraft engine cylinders, issued through the NASA Technical Reports Server for engineers and researchers. Its single picture is a photograph of three stacked sections of a cylinder assembly, shown as dark curved metal rings above a finned half-cylinder with exposed wiring and bolts, all on a plain pale ground, which suits a designer seeking industrial machinery texture and mechanical detail.
