Abstract
Wind offers vast opportunities in terms of energy potential. Previous studies have shown that wind power can meet all the world's energy needs by using effective wind turbines. However, the efficiency of wind turbines is not at the expected level, and they are not widely used due to various reasons. In this sense, it is substantial to yield airfoils with better aerodynamic properties. Geometrically, wind turbines are divided into two types as horizontal and vertical axes. Within the scope of this study, it was aimed to design a modified airfoil including both horizontal and vertical axes properties. Accordingly, a hybrid design was made in terms of the airfoil axis obtained by the modification of the NACA4412 profile. In terms of the method of the study, the electric generation efficiency of hybrid airfoils with different inclinations was measured under constant distance and air flow. As a result of the study, it was attained that the modified airfoil curved at an angle of 30° was about 12% more efficient in terms of electricity generation than the unmodified one.
