Structural details of German gliders
This is a 1927 NACA Technical Memorandum, No. 439, from the NASA Technical Reports Server, compiled for aeronautical engineers to document structural details of German gliders. The pages are numbered figures of fittings, hinges, wing spars and tail skids drawn in plain line technical style. A designer could take from them the clean schematic conventions of early engineering diagrams, with labelled parts, dimensioned hardware and simple monochrome linework suited to technical infographics.
