Structural Analysis of a Wind Turbine Blade

Abstract:

Wind turbines blades of propeller type are made according to various blade profiles such as NACA, LS, and LM. There are many factors for selecting a profile. One significant factor is the chord length, which depend on various values throughout the blade. In this work a NACA 4412 profile was created using DESIGN FOIL software to obtain the coordinates of a wind turbine blade in PRO/E. Aerodynamic analysis was done on the created design. Maximum lift to drag ratio was calculated by varying angle of attack of the blade. To find a suitable composite for wind turbine blade, Modal and Static analysis were performed on the modified design using Carbon fiber, E-Glass, S-Glass and Kevlar fiber composites in ANSYS APDL 12.0 software.
