The Magnus Effect in Theory and in Reality
A 1930 technical report from the NASA Technical Reports Server, a scientific paper on the Magnus effect, the force on a spinning body moving through a fluid. Its figures are line diagrams of streamlines and circulation around cylinders and spheres, drawn for engineers and physicists working on aerodynamics. A designer might borrow the flowing curved streamline lines and the nested circular vortex motifs as clean, schematic visual patterns.
