The need for use of renewable source of energy for green electricity production is increasing day by day. Wind turbine blade must be designed aerodynamically to achieve optimum performance in both design and off design conditions. In present study eight different study eight different blades for 700 watts scaled radio of 4 we are fabricated. The sections of wind turbine blade are selected from NACA series. The blades are tested in wind tunnel and their lift and drag at various angle of attacks were observed. From the test results, power for various blades were calculated and compared to get the optimum blade for 700 watts wind turbine. For a small scale wind tunnel experimental work can be carried out to find out the optimized rotor blade for the selected configurations.
