Vertical axis wind turbine with pultruded blades |
摘要 |
A pultruded composite blade for a Darrieus-type vertical axis wind turbine is disclosed, along with a method for fabricating such a blade. The blade is a composite structure with a uniform cross-section with reinforcing fibers at least some of which extend parallel to a lengthwise central axis and run continuously from end to end. The composite blade is pultruded straight and, when installed on the tower, the blade is elastically bent into a curved shape that approximates a troposkein. The composite structure includes a skin composed of multiple layers of resin-coated glass fabric that define an airfoil shape. The composite structure also includes one or more internal ribs or spars composed of multiple layers of resin-coated glass fabric.
