Design of wind turbine blade

A publication of the « International Journal of Electronics, Electrical and Computational System » : Design and Material Optimization of 1.5MW Horizontal Axis Wind Turbine Blades with Natural Fiber Reinforced composites using Finite Element Method.

Global warming as well as increasing environmental awareness,also depletion of fossil fuelsdiverts the attention of both developing and developed countries towards non-conventionalenergy sources like wind a pollution free source of energy.
India is the fifth largest wind power producer in the world, many researches are going in India regarding wind energy power production system. This is one such work aiming at weight reduction of wind turbine blades by using hybrid composites, where 1.5MW wind turbineblades areconsidered which is highly used in the region of Visakapattanam at an
average cut-out windspeed range of 14 to 21m/s. The blades are designed and analyzed with different Natural Fiber Reinforced composite materials their weight, static and dynamic performances are compared. From the results obtained it identified that natural fiber reinforced blades weigh less than the glass fiber blades with competitive performance. Modeling and analysis of wind turbine blade have been done using UNIGRAFIC-NX (NX-CAD &NX-NASTRAN) software.
