This study aims at documenting the flow characteristics of the Pennsylvania State University Low-Speed, Low-Turbulence Wind Tunnel. The spatial uniformity, turbulence intensity and spectra were measured and are presented here. The airfoil measurements made in the tunnel are shown to have good agreement with those made at Low-Turbulence Pressure Tunnel (LTPT) at the NASA Langley Research Center and the Low-Speed Wind Tunnel at Delft University of Technology in The Netherlands. The flow quality is concluded to be high and well suited for reliable two-dimensional airfoil characteristics measurements.
