The effect on engine performance of change in jacket-water outlet temperature
A 1933 NACA technical note from the NASA Technical Reports Server, issued for aeronautical engineers and researchers, presenting engine performance data. Its single figure is a line graph of horsepower against altitude in feet, plotting indicated and brake horsepower curves at several jacket-water outlet temperatures. A designer could take from it a clean, minimal technical chart layout, with thin multi-line plots, dashed and solid line styles, and a plain grid suited to data-visualisation reference.
