An Experimental Study of the Unsteady Aerodynamics of a Static DU91‐W2‐150 Airfoil at Large Angles of Attack

An Experimental Study of the Unsteady Aerodynamics of a Static DU91‐W2‐150 Airfoil at Large Angles of Attack

ABSTRACT The airfoil DU91‐W2‐150 was investigated in the Low Speed Low Turbulence Tunnel at the Delft University of Technology to study unsteady aerodynamics. This experimental study tested the airfoil under a wide range of angles of attack (AoA) from 0° to 310° at three Reynolds numbers (Re) from 2...
