Optimized Design of Rotor Blade for a Wind Pump

Design of a rotor of a wind mill is very crucial to harness wind energy. The aerodynamic design of rotor involves optimizing the rotor and its components to produce maximum power co-efficient which is the ratio of actual rotor output to the wind energy available for a given rotor area. The design of a wind mill although looks simple but involves complex and detailed design of its components like rotor, transmission, load matching, yawing mechanism etc. In addition it also involves study of wind and estimation of its power carrying capacity. In this paper, a rotor for wind mill at Bagur of Hosadurga district (Karnataka) is designed to achieve maximum power coefficient by optimizing various parameters like no. and shape of blades, chord width, tip speed ratio etc.
