Central Aerohydrodynamic Institute of Moscow, Russia
This is a 1926 NACA technical memorandum from the NASA Technical Reports Server, a Russian-language-era report on the Central Aerohydrodynamic Institute in Moscow, written for aeronautical engineers and researchers. The pictures are black-and-white line drawings and photographs of wind tunnels, a windmill test tower, and a windmill, plus technical diagrams of vortex flow curves and a hyperboloid-like surface. A designer might take from them the spare, diagrammatic style of early engineering figures, with clean dimensioned plans and sharp contrast in the photographs.
