Free-spinning Wind-tunnel Tests of a Low-wing Monoplane with Systematic Changes in Wings and Tails III : Mass Distributed Along the Wings
This is a 1938 NACA technical report, issued by the National Advisory Committee for Aeronautics, on free-spinning wind-tunnel tests of a low-wing monoplane model with varied wings and tails. The photographs show wooden test models of fuselages and tail units, and a rack of wing planforms, documenting the experimental series for aircraft engineers. A designer could take from them the clean, schematic look of early aeronautical test models photographed against plain backdrops, with strong sculptural silhouettes.
