Air resistance measurements on actual airplane parts
This is a 1923 NASA Technical Reports Server record of aeronautical research on air resistance tests of real aircraft components, presented as technical report figures. The pictures are engineering line drawings of landing gear and strut assemblies with labelled dimensions and sections, plus a graph of drag coefficients against wing loading and a set of streamlined strut cross-section profiles. A designer could take from them the clean diagrammatic style of mechanical technical drawing, with lettered callouts, dashed centrelines and stepped data plots.
