Structural Analysis and Design of Small Wind Turbine Blade

Abstract

Wind turbine blades represent a key component of wind turbines, which extract energy from the wind. In the present study, the structural design of a small wind turbine blade is undertaken using a numerical analysis. The reliability of numerical results is verified through a comparison with the full-scale structural test data of a current blade. To modify the blade design, the blade was divided into several sections and the effect of the thickness of each section was investigated in a numerical analysis. Finally, the modified blade was designed with a lightweight and high-strength.
