Span Load Distribution on Two Monoplanes Wing Models as Affected by Twist and Sweepback
This is a 1930 NACA technical report, issued by the National Advisory Committee for Aeronautics as a research note on wing aerodynamics, presenting wind-tunnel test results for monoplane wing models. Its pages are engineering plots of normal force coefficient against angle of attack, with curves labelled by sweepback and twist settings, aimed at aircraft designers and aerodynamic researchers. The pictures are plain grid charts with ruled axes, dashed and solid curve families, and small typeset captions; a designer might take from them the restrained graphic logic of technical data graphs, with evenly spaced grids and clean labelled curves.
