Establishing large-scale wind turbine blade CAD model based on reverse engineering

Wind turbine blades are the key parts of wind turbine. The large-scale wind turbine blade contour design and the choice of wing section both affect the wind turbine performance and the energy efficiency. The current research based on reverse engineering CAD technique to redesign the large-scale wind turbine blade, has incorporated the measurement of a large set of blades and use of reverse CAD modeling, the post-processing of data, precision analysis and the resize to original state. This paper describes a complete set of unique and novel techniques which constitute the principles and methodology for large scale wind turbine blade reverse engineering and redesign.
