Air Forces Exerted on Streamlined Bodies with Round or Square Cross- Sections, When Placed Obliquely to the Airstream
A 1924 technical report from NASA's Technical Reports Server, a scientific paper on aerodynamics written for engineers and researchers, covering air forces on streamlined bodies placed obliquely to an airstream. Its single picture shows two airfoil-like profile outlines with shaded cross-sections and arrows marking airflow, above a line graph of lift coefficient against angle plotted with symbol-marked data points and labelled curves. A designer could take from it the clean, minimal diagram style: thin black outlines, hatched fills, and plain axis-and-curve charting.
