Experiments with suction-type wings
This is a 1935 NACA technical memorandum, Technical Memorandum No. 773, issued by the National Advisory Committee for Aeronautics as a report for aeronautical engineers and researchers. The pictures are engineering graphs of pressure distribution and lift results, plus line diagrams of wing sections showing flap and slot positions and drilled pressure-measurement holes. A designer might take from them the clean, labelled style of 1930s technical plates, with simple airfoil profiles and curve plots that read well as schematic graphics.
