Abstract:

An experimental investigation was performed on the effectiveness of circulation control in producing additional lift and preventing separation on a cambered elliptical airfoil section with a rounded trailing edge. Steady blowing and pulsed blowing from a slot near the rear of the airfoil were used for circulation control. Downwash studies were conducted for the airfoil using potential flow theory, and Reynolds number effects were studied for the no blowing case. Airfoil surface-pressure distributions are presented for the various test conditions. Author
