Structural optimization study of composite wind turbine blade
TL;DR: In this paper, the initial layout of a 2MW composite wind turbine blade is designed first and the new airfoils families are selected to design a 2 MW wind turbine turbine blade The finite element parametric model for the blade is established based on the modified Blade Element Momentum theory, a new one-way fluid-structure interaction method is introduced a procedure combining finite element analysis and particle swarm algorithm to optimize composite structures of the wind turbine blades is developed.
