Wind turbines are one of the renewable energy resources. Wind turbines will be best solution to decrease the
pollution produced byfossil fuel operated power generators. In this paper typical 1.7MW wind turbine is designed and
performance analysis is carried out on the same. The aerodynamic contour design is one of the important thing to be
noticed in wind turbine blade. So for the horizontal axis wind turbine blade the program for optimization design of the
blades aerodynamic contour has been solved using MATLAB tool based on design process of Wilson method. According
to the space coordinate transformation theory, the space coordinates of the blade elements have been calculated. From
the coordinates generated wind turbine blade is modelled in CATIA. Then hub is also designed in CATIA. The first 6
order inherent frequencies and vibration modes of Blade and Hub are solved in ANSYS to verify the design. Modal
analysis is selected in ANSYS to solve the inherent frequencies and vibration modes in ANSYS.
