The Effect of Airfoil Thickness and Plan Form on Lateral Control
This 1924 NASA technical report on aircraft wing sections, issued by the NASA Technical Reports Server collection, was written for aeronautical engineers testing how airfoil shape and aileron placement affect roll control. Its plates are line graphs of lift and rotational data across angles of attack and speeds, plus a photograph of a wind-tunnel balance apparatus and a wing model on a stand. A designer could draw on its clean, technical charts for graph layouts, grid styling, and the stark look of early engineering diagrams.
