Tests of NACA 0009, 0012, and 0018 Airfoils in the Full-Scale Tunnel
This is a 1939 NACA technical report by the National Advisory Committee for Aeronautics, issued as a NASA Technical Reports Server scan, presenting wind tunnel tests of 0009, 0012 and 0018 airfoil sections in the full-scale tunnel for aeronautical engineers. The pictures show metal airfoil models, mounting supports, a tip fitting and a plotted lift and drag chart. A designer could take from them the clean, technical look of early aerodynamic test photography and graphs.
