The Effect of Small Angles of Yaw and Pitch on the Characteristics of Airplane Propellers
A 1932 NASA Technical Reports Server report, issued by the National Advisory Committee for Aeronautics, on how small yaw and pitch angles affect airplane propeller performance. Its pages mix wind-tunnel photographs of propeller test rigs with plotted performance curves for designers and engineers. The photographs show a propeller mounted in a large tunnel with a fuselage model, and a designer might draw on their stark industrial geometry and the clean graph lines of the charts.
