Annual Report of the National Advisory Committee for Aeronautics (9Th).Administrative Report Including Technical Reports Nos. 159 to 185
This is an annual administrative report of the United States National Advisory Committee for Aeronautics, its ninth, compiled in 1924 and including technical reports 159 to 185 for government and research readers. The pictures are engineering plates: pressure-distribution contour maps and wind-tunnel model photographs of wing and aircraft surfaces, with plotted curves and numbered lines. A designer could take their dense topographic-style contour patterns and fine hatched line work as abstract texture and diagram structure.
