Aerodynamic coefficients and transformation tables
A NASA technical report from 1918 containing aerodynamic coefficient and temperature conversion tables, distributed through the NASA Technical Reports Server. The single picture is a scanned chart plotting centigrade against Fahrenheit on a fine grid, with a straight diagonal line and two printed conversion formulas in a boxed label. A designer might take from it a clean engineering-graph aesthetic: dense fine grid lines, labelled axes, and a single diagonal trend line.
