    In this study, power coefficients of miniature wind turbine rotors produced by using NACA profiles were determined. To this end, an open system for wind turbine rotor model was established. In this test system power values of the wind that reach to each of the rotor form and tip speed ratios of each rotor form were indicated. With the help of these data, power coefficients of each rotor form were calculated. It was found that power coefficient values that were obtained in the study changed between 0,316 and 0,416. It was determined that 4-bladed rotors that were produced by using NACA 4415 and NACA 5317 profiles, having 0 degree twisting angle and approximately 10 degrees binding angle, had the highest ideal power coefficient values.
