Determination of Boundary-Layer Transition on Three Symmetrical Airfoils in the NACA Full-Scale Wind Tunnel
A 1938 NASA technical report, issued by NACA for aeronautical engineers and researchers, documenting boundary-layer transition measurements on three symmetrical airfoils tested in the full-scale wind tunnel. Its single plate is three side-by-side line graphs of section lift coefficient against transition-point position at several Reynolds numbers, with curves sweeping downward and to the right across each panel. A designer could borrow the clean grey grid, tidy caption typography and sparse black curve lines as a technical chart motif.
