Abstract: The wind turbine is a device that converts the kinetic energy of wind into electrical energy by generated motion. Wind turbines are an increasingly important source of intermittent renewable energy. As increasing the output power, the turbine rotational speeds increases. There are many parameters that effect on the horizontal axis wind turbine efficiency such as the blade design (geometry), material, and the attack angle. The attack angle is the angle between the blade chord and the wind stream lines. In this research, an experimental investigation was conducted for the effect of changing in the blade design (geometer), material, and attack angle in the small turbine revolution per minute (output power and performance). The optimum blade geometry was narrow width profile and the best attack angle was found 70°. Moreover, epoxy resin imbedded with carbon fiber is the most suitable material for the blade to have better performance.
