Characteristics of the NACA 23012 Airfoil from Tests in the Full-Scale and Variable-Density Tunnels
This is a 1936 NACA technical report on the NACA 23012 airfoil, tested in the full-scale and variable-density wind tunnels, published for aeronautical engineers and researchers. The single photograph shows the airfoil mounted on vertical struts inside the full-scale wind tunnel, with a large circular fan duct at left and a figure standing on the floor for scale. A designer could take its stark industrial setting, bare steel bracing and bold diagonal composition as a reference for technical, measurement-driven imagery.
