New airfoil families for horizontal-axis wind turbines

It is found that the usage of conventional aircraft airfoil sections is not the proper choice for wind applications due to the difference in design objectives and the environment of application. Adopted aircraft airfoils for horizontal-axis wind turbines including NACA 44XX and NACA 230XX have expe...
