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.
