Manufacturing-oriented bionic design method for wind turbine blade

Traditional wind turbine blade design theory carried on the design theory of airplane wing, but classical air dynamics can not make an agreement between the wind capture efficiency, cost and mechanical performances of wind turbines. Based on the natural optimum growth roles, a new bionic topology design method for wind turbine blade has been investigated in this paper, and the mechanical performance using the bionic design method has been compared to that designed by one of the traditional method. The numerical result shows that the new designed model performs better in some aspects of the blade’s mechanical behavior, such as the static strength, stiffness and fatigue strength.
