Interference Effects and Drag of Struts on a Monoplane Wing
This is a 1931 NACA technical report from the National Advisory Committee for Aeronautics, issued in the United States for aeronautical engineers and researchers, studying how wing struts add drag and interfere with airflow on a monoplane wing. Its plates are plain engineering graphs of lift and drag coefficients, precise line drawings of strut and wing sections, and a diagram of the wind tunnel used, offering a designer clean technical charts and schematic linework.
