THREE-DIMENSIONAL SOLID MODELING OF LARGE WIND TURBINE BLADE BASED ON WILSON THEORY

摘要

This paper discussed the problems of design complexity and modeling difficulty for the large wind turbine blades, According to Wilson theory and BEM theory, Matlab was used to calculate chord length, torsional angle and coordinate transformation. The coordinates were outputted automatically. The result obtained from the program was transmitted directly into Pro/E, and the 3D modeling of large wind turbine blades was achieved. This method accomplishes the programming design and the parameterized modeling, thus enhances the efficiency of the design and precision of modeling.
