Abstract
This paper presents a detailed study on the design optimization of wind turbine blades using Finite Element Analysis (FEA). Wind turbine blade performance directly influences the efficiency and reliability of wind energy conversion systems. The study focuses on structural and aerodynamic performance, aiming to reduce blade weight while maintaining mechanical strength and minimizing deformation under operating loads. A parametric blade model was developed and analyzed using FEA to evaluate stress distribution, deformation, and natural frequency. The optimization process used classical material and geometric properties relevant to 2021 technologies, ensuring practical applicability. The results demonstrate significant weight reduction potential with improved structural performance, offering valuable insights for sustainable wind turbine blade design.
