English airplane construction
This 1930 NACA technical memorandum, issued by the National Advisory Committee for Aeronautics as a report on English aircraft construction, collects numbered figures of metal airframe parts for engineers and aircraft designers. Its pages are ruled line drawings and grainy photographs of spars, struts, fittings and fuselage junctions, showing how steel tube and duralumin members were joined, useful to a designer studying riveted lattice structure and mechanical joinery.
