The Aerodynamic Forces and Moments Exerted on a Spinning Model of the NY-1 Airplane as Measured by the Spinning Balance
A 1934 report plate from the National Advisory Committee for Aeronautics, published by NASA's Technical Reports Server, showing a wind tunnel test rig for an aircraft model. The photograph shows a scale airplane model mounted on a spinning balance apparatus beneath the curved enclosure of a large test chamber, with the plate's caption printed below. For a designer, the image offers a stark, technical view of laboratory machinery, with its overhead curve and dark metal tones suited to industrial or engineering themes.
