Aerodynamic characteristics of aerofoils II : continuation of report no. 93
A 1923 NASA technical report, continuing report no. 93 on aerofoil aerodynamics, issued by the National Advisory Committee for Aeronautics for engineers and aircraft designers. The single page shows four small graph panels of lift and drag curves plotted against angle of attack, with data tables in the upper left of each and labelled plot axes. A designer might take from it the clean, dense scientific chart style with grid lines, tabulated numerals and thin black curves.
