System and method of distributing air within a wind turbine

摘要

An air distribution system (30) for use with a wind turbine (10), the wind turbine including a nacelle (16) coupled to a tower (12) and a rotor (22) rotatably coupled to the nacelle with a rotor shaft (24), and the rotor including at least one rotor blade (28) coupled to a hub (26) is provided. The air distribution system includes a conduit (93) defined within the rotor shaft, the conduit providing flow communication between the nacelle and the rotor, and an air-flow control assembly (40) coupled in flow communication with the conduit, the air-flow control assembly configured to selectively channel air from the nacelle to the rotor and from the nacelle to ambient air (56).
