Systematic Airfoil Tests in the Large Wind Tunnel of the DVL
This 1938 NASA technical report, drawn from the NASA Technical Reports Server, records systematic wind tunnel tests of airfoil lift coefficients at the German DVL large wind tunnel, written for aeronautical engineers and researchers. Its pages show plotted curves of maximum lift coefficient against Reynolds number for several symmetric and cambered airfoil sections, with one photograph of a wing model mounted on a test rig. A designer could take from these clean, grid-based graphs a restrained, technical visual language of thin curves, tick marks and labelled series.
