The 7 by 10 Foot Wind Tunnel of the National Advisory Committee for Aeronautics
This is a 1933 technical report from the National Advisory Committee for Aeronautics, documenting its 7 by 10 foot wind tunnel for engineers and aeronautical researchers. The photographs show the large tunnel's test section, mounting frames, and a technician adjusting a model wing, while the line drawings label the floating framework and lift and rolling moment members. A designer could draw on the stark industrial photography and precise labelled diagrams for technical, engineering-style layouts.
