Force Measurements on a 1/40-scale Model of the U. S. Airship "Akron."
A 1933 NASA technical report, compiled from the NASA Technical Reports Server, on wind-tunnel force measurements taken on a 1/40-scale model of the U.S. Navy airship Akron, written for aeronautical engineers. The two photographs show the model mounted in a laboratory wind tunnel, with a large fan or propeller at the tunnel mouth behind it, a technical record a designer might use for streamlined, cigar-shaped forms.
