Construction of Models for Tests in Wind Tunnels
A 1920 technical report on building scale models for wind tunnel testing, issued as a NASA Technical Reports Server scan from an early aeronautics publication for engineers and researchers. Its plates are plain black-and-white photographs of carved wooden airfoil sections, a model wing with fittings, a wind tunnel mounted instrument, and a thin tapered blade shot at an angle, with no decorative content for designers beyond the stark industrial look of early aerodynamic test apparatus and the precise geometry of tapered wing profiles.
