Men stand in front of the round courses inside Awt Wind Tunnel (AWT) At the National Consulting Committee of the Air Force Air Motor Research Laboratory in the form of advertising in February 1944, the photo was taken a few weeks after the tunnel operation.
AWT was the only wind tunnel to test fully -sized aircraft engines in simulating height conditions. A large fan of a wooden motor is created, located on the other side of these motives, wind speeds of up to 500 mph. Each corner of the rectangular tunnel had rotating circles, which corrected the air flow and its faces around the corners. This group of rounds was in the southeastern corner, which is 31 feet long from the tunnel. These elliptical panels consist from 36 to 42 vertical countries that were supported by three horizontal pillars. The individual rounds were 2.5 feet and half the moon. Each group of rounds lasted for assembly weeks before installing them during the summer of 1943.
Aircraft engine research laboratory has gone through several updates and changes through the history of NACA and NASA; It is now the NASA Glen Research Center in Cleveland.
