A study of the pitching moments and the stability characteristics of monoplanes
A 1934 NASA technical report on the pitching moments and stability of monoplane aircraft, prepared for aeronautical engineers and aircraft designers. Its pages are dense engineering charts plotting moment coefficients, stability factors and wing parameters against angle of attack, with curves labelled for heavy and light centre-of-gravity positions and high and low wings. A designer might take little from the plots directly, but the stepped grid layouts and clean curve families show how technical data can be presented with restraint.
