Abstract : The low-turbulence wind tunnel was designed primarily for the investigation of frictional resistance phenomena but is not restricted to these applications. Velocity and pressure surveys were made of the tunnel as a function of fan speed. The turbulence level was measured and found to be above the 0.05 percent sought in the original design but far below the levels which appear in the boundary layers, jets, wakes, etc. The wind tunnel is adequate for experimental investigations, but the versatility and accuracy are somewhat limited due to the space in which the tunnel was constructed.
