Design & Analysis of Wind Turbine Blade

Abstract

In the wake of drastic depletion of conventional energy sources, there is a high demand for the non- conventional alternatives. Wind turbines provide an alternative way of generating energy from the power of wind. At windy places where the wind speeds are so high, sufficient amount of energy can be harnessed by making use of wind turbines. The blades of such turbines are so designed that they generate lift from wind and thus rotate. This work explores the finite element analysis of a Wind Turbine Blade using ANSYS software. Finite Element Analysis is a numerical method of deconstructing a complex system into very small pieces (of designated size) called elements. In this work, the wind turbine blade is modelled in CATIA V5 and analysed for five different blade materials viz., Structural steel, Stainless steel, Titanium Alloy, Aluminium Alloy, T-Graphite Epoxy. The aim of the analysis is to validate the strength of the blade and compare the above materials to select the best material for the wind turbine blade. analysis are the Grid and
