- The purposes of this study are to investigate effect of number of blades on a non-twisted blade wind turbines type airfoil NACA 4415 on the electrical power generated. Experimental study is used on this research. The sample was Horizontal Axis Wind Turbine (HAWT) with non-twisted blades airfoil NACA 4415. There were three variation of the number of blades those were the number of blades of two, the number of blades of three, and the number of blades of four. Wind speed variation used in this study was 2.5 m/s, 3.5 m/s, and 4.5 m/s. The data collected by conducting test of HAWT by using artificial wind, electric power generated was read and recorded by data logger. The data from the research was put into the table and shown in the form of graphic, then analyzed. Based on the result of the research, it can be concluded that there was an effect of variation of the number of blades toward electrical power of wind turbines. Three blades HAWT produced the biggest electrical power that was 0.7222 W with 4.5 m/s of wind speed.
