Elementary principles of aeroplane design and construction; a textbook for students, draughtsmen, and engineers
A 1919 London textbook by Arthur W. Judge on aeroplane design and construction, written for engineering students, draughtsmen, and working engineers. Line diagrams show trussed fuselage frames with force arrows, undercarriage wheels and skids, force-vector sketches of a machine landing, and gridded curves of wing loading, all usable as technical drawing and annotated-diagram source material.
