Applications of Modern Hydrodynamics to Aeronautics. [in Two Parts
A 1923 NASA Technical Reports Server scan of a technical treatise on applying modern hydrodynamics to aeronautics, aimed at aerodynamic engineers and researchers. Its pictures are plain engineering graphs and diagrams: polar curves of wing lift and drag, lift coefficient plotted against angle of attack, airfoil pressure-distribution profiles, a vortex and circulation sketch, and a curve of lift distribution along a span. A designer might take from them the clean, sparse line-graph vocabulary of early aerodynamics, with dotted data points, labelled curves, and thin axes.
