BLADE ASSEMBLY FOR WIND POWER GENERATION, CAPABLE OF SMOOTHLY ROTATING EVEN IF WIND BLOWS FROM A DIRECTION PERPENDICULAR TO A ROTATING SHAFT

摘要

PURPOSE: A blade assembly for wind power generation is provided to enhance generation performance since a blade assembly can smoothly rotate by wind regardless of the direction of the wind.;CONSTITUTION: A blade assembly for wind power generation comprises a hub(10), arms(20), a frame(32) and a blade unit(30). The hub comprises a rotating shaft. The arms are rotatably coupled to the hub at regular intervals in the circumferential direction. The frame is coupled to each arm. The blade unit comprises first and second blades. The blades are coupled to the frame to have a ventilation hole on their joints. Cross section of the blade is an arc shape.;COPYRIGHT KIPO 2011
