This project aims to create and gather information about the shape of the impeller characteristics. NACA Airfoils shape by using the NACA, NACA 0018, 0025, 0021, NACA 0012 and NACA 0015, the size of the fan blades themselves on 12x100 cm on all blades. Leaves the wind rolled using polycarbonate sheet has a size of 20x120 cm. leaves. From the experimental results. Propellers is best efficient NACA 0012 at degree options in the 70° degrees 40 degrees, that the wind does not exceed 5 metres per second speed round Speed (rpm) 47.6 RPM. Voltage (v) Power (Torque), the torque 2.166 2.854 v N-m. Compared to the propellers for all degrees and every wind speed model NACA 0012 with the best performance.
