1. A wind turbine blade construction comprising an assembly of an airfoil profile and an unsymmetrical I beam,said airfoil profile elongated in a first direction and havingperpendicular to said first direction;

  • a single interior surface with engagement means for receiving and aligning said unsymmetrical I beam, an exterior surface corresponding to an aerodynamic shape with a leading edge and a trailing edge, said leading edge and said trailing edge connected by a chord line,said unsymmetrical I beam having a web section integral to two flanges, a first flange proximal to said leading edge and a second flange proximal to said trailing edge, with both said flanges bonded to said single interior surface at said engagement means in the completed turbine blade construction, withsaid web section having a medial plane roughly perpendicular to each of said two flanges and said medial plane forming a designed angle with said chord line in a plane perpendicular to said first direction,whereby;

    said beam can be easily modified and the airfoil profile customized to optimize performance in a particular application and said assembly can be produced using low cost, constant profile, mass production methods.
