AB In the last decade, we have heard more and more about the need of renewable
clean energy, but not much has been done. Currently, the wind power
energy is the most popular of all of these green technologies. Thousands of

many questions arise.
The aerodynamic loads on the rotor blades are the largest loads acting on
a wind turbine. The horizontal wind turbine types of blades are usually made
of two or three airfoils such as a propeller. In these types of blades, it is the
