Effect of structure in middle part of leading edge of a thick wing : communication from Rijks-Studiedienst voor de Luchtvaart of Amsterdam
This is a 1922 aeronautical technical report by the Rijks-Studiedienst voor de Luchtvaart of Amsterdam, issued through the NASA Technical Reports Server, examining how a structure on the leading edge of a thick aircraft wing affects airflow. The pictures are plain line drawings: a wing section outline with dimensions, a cross-section of a leading-edge model with lettered variants, and a graph plotting lift and drag coefficients across several models. A designer might take from them the clean, schematic engineering diagram style, with lettered callouts and dashed construction lines.
