Cooling Characteristics of a 2-Row Radial Engine
This 1937 NASA technical report, issued through the NASA Technical Reports Server, presents test data on how a two-row radial aircraft engine cools under varying conditions, written for aeronautical engineers. The pictures are plain line graphs with numbered curves, labelled cylinder temperature against airspeed, fuel consumption and manifold pressure, with thermocouple points marked. A designer might borrow their clean grid layouts, labelled axes and restrained tonal palette for technical charts.
