| Résumé : |
Currently, small wind turbines can hardly be operated profitably in landlocked regions. This drawback has now been overcome by the partners EAB Gebäudetechnik Luckau GmbH and the Chair of Polymer-based Lightweight Design at the BTU Cottbus-Senftenberg : passive smartblades made from 3D-printed molds adapt independently to wind conditions. This is achieved by an intelligent layer structure and its bending-torsion-coupling. |

- The inland path to profitable SWTs
- Efficient product development thanks to modern simulation technology
- CFD and FEM calculations : torsion under wind load
- Figure : This newly developed rotor blade is especially suited for weak-wind regions and adapts independently to the wind load
- Fig. 1 : Production-ready implementation of a rotor blade design with the profiles and the profile chord
- Fig. 2 : Distribution of pressure on the rotor blade and Tsai-Wu failure criterion (TSAIW). There is no damage to the laminate at TSAIW < 1
- Fig. 3 : Regression curves (polynomial, degree 6) of torsion angle over blade length at a wind speed of 20 m/s
- Fig. 4 : Development of the mold for manufacturing rotor blades. a) CAD model of the mold ; b) printed mold ; c) infusion of a rotor blade half ; d) rotor blade following gluing of both shell halves
- Table : Process parameters in the hybrid production of mold halves |
