Abstract
In this study aerodynamic performance of the different wind turbine airfoils that can work efficiently in the province of Kayseri weather conditions was investigated in subsonic wind tunnel. Firstly, the theoretical study had been done and 3 airfoils (S826, NACA 4415, NACA 63-415) were determined. Aerodynamic parameters (CL, CD, CL/CD) of the airfoils manufactured in the model airplane workshop was measured by a Gamma type force/torque sensor (loadcell). Experiments was carried out between -4ᵒ and 26ᵒ angle of attack at 3 different velocities (6-7-8 m/s, 126000-147000-168000 the Reynolds number). According to the obtained results NACA 63-415 airfoil showed that CL/CD values are about 7 between 4ᵒ and 12ᵒ angle of attack when others are 4. After the angle of attack of 12ᵒ CL/CD values of NACA 63-415 airfoil decreased and until the angle of attack of 21ᵒ this airfoil has higher lift / drag ratios then other airfoils.As a result, wind power plants operating at low speed can be established in Kayseri with NACA.63-415 airfoil that has concluded that it is better to use in terms of efficiency.
