The effect of curvature on the transition from laminar to turbulent boundary layer
A 1937 NASA technical report on how curved surfaces shift the transition from smooth laminar to turbulent airflow in a boundary layer, written for aeronautical researchers. Its single plate is a dense engineering graph on a fine grid, with several curving stability boundaries plotted against axes and a figure caption set in small type along the lower right margin. A designer might take its grid-and-curve structure as a plain, technical chart motif for diagrams, data backgrounds, or minimalist scientific layouts.
