Apparatus and method for cleaning an active flow control (AFC) system of a wind turbine
First Claim
1. An active flow control (AFC) system for use with a wind turbine that includes at least one rotor blade, said AFC system comprising:
- 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 said at least two manifolds;
a gas supply coupled in flow communication with said at least two manifolds;
an AFC controller operatively coupled to said gas supply and configured to determine that at least one manifold of said at least two manifolds is fouled; and
a valve system coupled in communication with said AFC controller and operatively coupled to said gas supply, said valve system configured to block a gas flow to a first manifold of said at least two manifolds to redistribute the gas flow to a second manifold of said at least two manifolds upon the determination that the at least one manifold of said at least two manifolds is fouled.

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.

14. A method for cleaning at least one manifold of at least two manifolds at least partially defined within at least one rotor blade of a wind turbine having an active flow control (AFC) system, a gas supply in flow communication with the at least two manifolds, said method comprising:
-
operating the AFC system in a first mode; determining whether a first manifold of the at least two manifolds is to be cleaned; and operating the AFC system in a second mode different than the first mode upon determining that the first manifold is to be cleaned, a gas flow rate through the first manifold during the second mode being higher than a gas flow rate through the first manifold during the first mode. - View Dependent Claims (15, 16, 17, 18, 19, 20)
