ABSTRACT:
An air distribution system for use with a wind turbine. The wind turbine includes a nacelle that is coupled to a tower and a rotor that is rotatably coupled to the nacelle with a rotor shaft. The rotor includes at least one rotor blade that is coupled to a hub. The air distribution system includes a conduit that is defined within the rotor shaft. The conduit provides flow communication between the nacelle and the rotor. An air-flow control assembly is coupled in flow communication with the conduit. The air-flow control assembly is configured to selectively channel air from the nacelle to the rotor and from the nacelle to ambient air.
