Power consumption is increasing day by day but supply is not catching up with the demand. Also depletion of conventional fuels puts the world in a critical position. Hence, unconventional fuels such as air, wind, tidal, geo-thermal, bio- fuels, hydropower plants etc. should take over the conventional resources. wind as one of the sources of energy is being used since long time. It has gained more significance in the current age of energy crisis, as it is non- polluting, abundant, freely available and low maintenance. Design and usage of horizontal axis wind turbines are well defined over the past couple of decades, but vertical axis wind turbines did not get much attention. Recent research is centered on vertical axis wind turbines due to its inherent advantage of simplicity in control over horizontal axis wind turbine. the durability and high life time of wind turbine can be ensured, among others, if the wind blade materials have very high stiffness, strength, corrosion, fatigue damage, environmental loading resistance as well as low weight. for this, composite should be utilized for wind turbines in place of conventional alloys. Modelling of staring symmetrical blade for a small scale vertical axis wind turbine is done using commercial software package CATIA. Using beam theories, approximate values of stresses and deflections for the alloy and composite materials are calculated and the values are validated by analyzing the above modeled blade by using numerical analysis results with the help of FEM package, ANSYS. The vibration parameters for vertical axis wind turbine such as natural frequencies and mode shapes blade were done with the help of Block Lanczos method. From the modal analysis composite straight bladed vertical axis wind turbine blade has low natural frequency compared to the blade made up of Aluminum material, from the static analysis, the minimum stresses and maximum deformations are developed in composite vertical axis wind turbine blade material when compared with the Aluminum blade material VAWT blade.
