ABSTRACT:
An active flow control (AFC) system for use with a wind turbine is provided. The wind turbine includes at least one rotor blade. The AFC system includes at least two manifolds at least partially defined within the at least one rotor blade, at least one aperture in flow communication with each manifold of the at least two manifolds, a gas supply coupled in flow communication with the at least two manifolds, and a valve system operatively coupled to the gas supply. The valve system is configured to block a gas flow to a first manifold of the at least two manifolds to redistribute the gas flow to a second manifold of the at least two manifolds.
