Recent Experiments at the Gottingen Aerodynamic Institute
A 1925 aeronautics report issued through NASA's Technical Reports Server, describing wind-tunnel experiments on airfoils carried out at the Göttingen aerodynamic institute for aerodynamics researchers. The pictures are plain technical graphs and tables: lift and drag curves plotted against angle of attack, families of curved lines for different camber and thickness, and a grid of Joukowski airfoil profiles, all in black ink on white paper, giving a designer a clear reference for early aerofoil section shapes and their performance curves.
