Patent abstract

An optimally-shaped single part molded wind turbine blade is provided for small wind turbines. Two mold bodies are brought together to form a cavity, and a third retractable mold body is inserted into the cavity. A flowable material such as filled thermoplastic resin is introduced into the space between the mold bodies and solidified. The retractable mold body is retracted and the mold is opened to reveal a single-part wind turbine blade with a hollow root region.
