Definitions

  • Wind blade shells are formed using tools. Such tools must have precise shapes in order to form shells that are sufficiently aerodynamic for use in wind turbines. Such tools are typically formed using molding and machining. For example, a male plug is made using machining, on which a female mold shape is made, after which a production mold is made by joining the female mold shape within a steel frame. However, such molding and machining can be time consuming and expensive. There is a need for wind blade shell tools that can be manufactured at reduced cost and/or more quickly.
