Model tests with a systematic series of 27 wing sections at full Reynolds number
This is a 1926 NASA Technical Reports Server publication of wind-tunnel model test data, a report on a systematic series of 27 aerofoil sections tested at full Reynolds number. It was issued for aeronautical engineers and researchers studying wing performance. The pages are rows of lift-coefficient graphs labelled NACA-M3 through NACA-M12, each paired with a small cross-section drawing of its wing profile. A designer could take from them the plain engineering vocabulary of graph axes and thin airfoil outlines, useful as a source of aerofoil silhouettes.
