An Airfoil Spanning an Open Jet
This is a 1933 NASA technical report on wind tunnel testing, issued through the NASA Technical Reports Server, presenting aerodynamic data for engineers and researchers. The pictures are plain line graphs in rows of small panels, each tracing a pressure curve with circular data markers against a horizontal baseline, plus one dense bar chart of grey vertical columns on a gridded field. A designer might take the repeated small-multiple grid layout and the clean marker-dotted curves as a restrained template for arranging data.
