Full Scale Tests of Wood Propellers on a VE-7 Airplane in the Propeller Research Tunnel
A 1929 NACA report on full-scale wood propeller tests on a VE-7 airplane, issued by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers. Its pages are mostly paired line graphs of thrust, power and efficiency against advance ratio, plus dimensioned propeller blade drawings with plan and side views; a designer could take from them the clean grid-and-curve plotting style and the technical drafting of airfoil outlines.
