Abstract

To validate an accurate, rapid, two-dimensional, wind-tunnel test capability at low Reynolds numbers, the E 387 airfoil has been investigated in The Pennsylvania State University Low-Speed, Low-Turbulence Wind Tunnel over the range of Reynolds numbers from 60,000 to 460,000. Comparisons with results from the NASA Langley Low-Turbulence Pressure Tunnel, the Delft University of Technology Low Speed Laboratory, and the University of Stuttgart Model Wind Tunnel show excellent, good, and fair agreement, respectively. Comparisons with predictions from the Eppler and MSES codes show good agreement. The validation of the test capability is a prerequisite of the design and verification of high-lift, low pitching-moment airfoils for VTOL UAVs to follow.
