Small wind turbines are mostly designed for strong and medium wind regions, which are scaled by manufacturers based on similarity rules. However, the inland region represents a low wind region where the commercially available blades are not profitable. In this work, a rotor blade was designed for these wind conditions and further performance improvement of the turbine was generated by self-adaptive adjustment of the blades to the variable wind loads. This adaptation is achieved by a ply structure that exhibits bending-torsion coupling. The tooling for the production of the GFRP rotor blades was manufactured using a large-format 3D extrusion printer.
