Airship Model Tests in the Variable Density Wind Tunnel
A 1932 NASA technical report on airship model wind tunnel testing in the Variable Density Wind Tunnel, presenting aerodynamic data and test setups for designers and engineers. The pictures are plates of lift and drag coefficient charts for airship fineness ratios, a line drawing of the closed-circuit tunnel, a view inside the tunnel fan, and a model airship mounted on struts in the test section. A designer might take the streamlined hull profiles, the grid-plotted curves, and the technical drawing layout as reference for sleek, technical graphics.
