Design Calculation of Horizontal Axis Wind Turbine Blade (1200W) for Rural Applications

Abstract

This paper provides to design 1200W horizontal axis wind turbine blade for rural application. The rotor blade is design to produce 1200W power output in order to install at Mandalay Hill of Mandalay City in Myanmar at rated wind velocity 7 m/s. The rotor diameter is 2.303m and tip speed ratio is 5. The design process includes the determination of the blade airfoil, pitch angle and chord length distribution along the blade span. By using blade element theory, blade is divided into 10 elements with equal length forming 11 sections throughout the blade. This paper is intended for commercial wind turbine in rural applications. The wind generator can produce 1200W at wind velocity 7 m/s. The use of wind energy for electricity is more economical than the conventional electricity generation. It is strongly recommended that the design prototype is economic and competitive for commercialization at any windy places in Myanmar.
