Determination of the characteristics of tapered wings
A 1937 NASA technical report on tapered wing aerodynamics, issued by the National Advisory Committee for Aeronautics for aeronautical engineers and wind-tunnel researchers. Its pictures are dense engineering charts with grids, curves, and tabulated coordinates plotting lift-to-drag ratio, lift coefficient, and drag coefficient against angle of attack, plus small diagrams of tapered wing planforms, useful to a designer as a source of precise technical graph layouts and line-based data visualization.
