A new relation between the induced yawing moment and the rolling moment of an airfoil in straight motion
This is a 1925 NASA technical report on aerodynamics, a paper on the relation between induced yawing moment and rolling moment of an airfoil in straight flight, credited to the NASA Technical Reports Server and aimed at engineers and aeronautical researchers. Its single plate is a graph of yawing moment coefficient against a second coefficient across a family of curves labelled by angle of attack from 0 to 40 degrees, drawn as plain black lines on a gridded field with small circular data markers. A designer could take from it the clean, technical look of early engineering charts: fine uniform grid, fanning curves converging on one origin point, and minimal labelling in serif type.
