The Design of Airplane Wing Ribs
A 1931 technical report from the NASA Technical Reports Server, originally issued by NACA-era aeronautical researchers for aircraft engineers and designers working on wing structure. The three plates show dimensioned drawings of wing rib profiles with internal truss and web layouts, plus a photograph of a wooden rib test assembly with spars and braces. A designer could take from them the clean, labelled engineering-drawing style and the skeletal lattice of struts that suggests structure and geometry.
