Flow phenomena on plates and airfoils of short span
This is a 1936 NACA Technical Memorandum No. 798 issued by the NASA Technical Reports Server, a government aeronautical research report on flow phenomena over short-span plates and airfoils, written for engineers and aerodynamicists. Its pictures are dense technical line graphs of lift, drag and moment coefficients plotted as polar curves and charts, plus one three-dimensional pressure distribution plot, all in grey and black; a designer might take from them only the abstract plotted curve patterns and grid structures rather than any visual subject matter.
