Wind tunnelIn 1929, the first high-speed jet wind tunnel was completed at Langley Field, California, the field laboratory of the National Advisory Committee for Aeronautics. Preliminary design work was begun 14 Nov 1928. A wind speed of about 600-mph was attained, permitting the testing of aerofoils at this speed. The tunnel has since been deactivated. |
