This is a 1922 technical report from the NASA Technical Reports Server, a record with no title, author or subject detail, so the pictures carry the content. They are line drawings of aerofoil test apparatus, with mechanical linkage diagrams, wind-flow sketches and a plotted lift-coefficient graph. A designer might take from them the clean, labelled engineering diagram style, with dimension lines, leader arrows and a figure-numbered caption system.
