Abstract
The Circulation Control Rotor concept makes it possible to achieve large changes in lift coefficient, without changing angle of attack, by making only small changes in blowing coefficient. The concept has great potential in the area of rotary-wing aerodynamics, where implementation will require the generation of oscillating blowing coefficients. In order to examine the response of a circulation control airfoil to such an oscillating blowing coefficient, a simple control valve system was designed and built. The effectiveness of the control valve in oscillating the blowing coefficient at various frequencies and amplitudes was examined. An attempt to determine the effect of this oscillation on the instantaneous lift coefficient of the rotor was not successful.
