Effect of Several Factors on the Cooling of a Radial Engine in Flight
This is a 1936 NACA technical report by the National Advisory Committee for Aeronautics, held in the NASA Technical Reports Server, written for aeronautical engineers and researchers studying radial aircraft engine cooling in flight. Its pictures are plain engineering graphs of thermocouple temperature readings and slope lines, plus photographs of a Pratt and Whitney engine cylinder with numbered sensor locations, showing measurement data and hardware layout a designer might use for technical diagram or instrument-panel inspiration.
