Parametric Analysis and Designing of Wind Mill Blade

Abstract

On the basis of elementary blade theorythe windmill blade is examined for its optimum twist. In this project new windmill model is designed and it is statically analysed by the ANSYS workbench software. When the blade is twisted the angle of attackalways depends inthe variation of the sectional lift as well asdrag coefficients.The highest power efficiency is accordingly attained in respect to the wind speed toblade angular velocity.The percentage of maximum-lift to that ofcoefficient angle of attack at the blade root isnearer to ninety two percent of this value at the blade tip of the air foil cross-section.The materials used were E-glass epoxy and S- glass fibre results were tabulated.
