This is a 1924 technical report compiled by NASA's Technical Reports Server from an earlier aeronautical publication, with no stated title or named author, likely written for engineers and aviation students. Its pictures are line-drawn exploded and labelled schematics of rigid and semi-rigid airships and a biplane airframe, with lettered call-outs and cross-section views a designer could borrow for diagrammatic labelling and technical line work.
