Liore-Olivier LeO 194 seaplane
This is a 1927 technical report from the NASA Technical Reports Server describing the Lioré-Olivier LeO 194 seaplane, issued as an engineering record for aviation engineers rather than a general reader. The pictures are black-and-white line drawings of aircraft parts: a fuel or oil system schematic with numbered callouts, a hull or float section with hatch and fittings, a cross-sectional hull profile with dimensions, and a close-up of riveted duralumin joints with inset detail circles. A designer could draw on their clean technical diagram style, numbered leader lines, and dimensioned sectional views for mechanical or schematic graphics.
