The Aerodynamic Characteristics of Six Full-Scale Propellers Having Different Airfoil Sections
This is a 1939 NASA technical report, issued by NASA's Technical Reports Server, presenting aerodynamic test data for six full-scale aircraft propellers with different airfoil sections, written for aeronautical engineers and researchers. The single picture is a dense line graph of drag and lift coefficient curves plotted against blade angle, with a legend of section types and blade angles; a designer might take from it the restrained grid-and-curve vocabulary of technical engineering charts, with thin black lines, small numeric axes, and tabular key boxes.
