Experimental Determination of Jet Boundary Corrections for Airfoil Tests in Four Open Wind Tunnel Jets of Different Shapes
This is a 1931 NACA technical report by NASA's Technical Reports Server collection, issued for aeronautical engineers and wind tunnel researchers, measuring airflow corrections for airfoil tests in open wind tunnel jets of several shapes. The photographs show the interiors of four open jet test sections, with circular and elliptical nozzle mouths facing each other across wooden walls, and one view of a model aircraft mounted in the jet. A designer could take from them the stark perspective of enclosed wooden test chambers with round openings, useful for industrial or technical mood imagery.
