Method of Curved Models and Its Application to the Study of Curvilinear Flight of Airships. Part II
This is a 1937 NASA technical report, Part II of a study on curved wind-tunnel models used to analyse curvilinear flight of airships, issued by the NASA Technical Reports Server from its aeronautics library holdings. The pictures are engineering graphs on squared grid paper: families of curved plotted lines with dashed and solid traces, labelled axes and small numeric tick marks, with one page showing a hull-and-tail-surface comparison and another a labelled flow-field chart. A designer might take from them the restrained grid-and-line vocabulary of mid-century technical charts, useful for data-visualisation layouts.
