The Vickers-Supermarine "Scapa" (British) : a military flying boat
This NACA Aircraft Circular from 1936 is a technical report issued by the National Advisory Committee for Aeronautics on the Vickers-Supermarine Scapa, a British military flying boat, for engineers and aircraft designers. The pictures are black-and-white engineering cutaways, exploded structural details, and photographs of hull sections and a wind-tunnel model, showing framing, bracing and hull shape in plain line drawings a designer could borrow for mechanical diagrams.
