A few more mechanical-flight formulas without the aid of polar diagrams
A 1928 technical report from the NASA Technical Reports Server, a collection of engineering papers, on aircraft performance calculations made without polar diagrams, drawn up for aeronautical engineers and students. The pictures are plain graphs and nomograms: curves of coefficients plotted against ratios, a dashed-and-solid line chart of kappa against h/b, and a three-scale alignment chart with a 90 degree construction line, all in black ink on white, suited to a designer borrowing their grid and label style.
