Abstract
The importance of renewable energy sources cannot be denied in the era of increase of greenhouse gas emission and depletion of fossil fuels. The wind energy and design of new yet effective windmills become a necessity nowadays. This paper introduces a new configuration of wind turbine with a horizontal axis and ANSYS-based dynamic analysis of its high-speed protection shield that protects the turbine from overspending at extreme wind conditions. In comparison to traditional horizontal wind turbine structure, HAWT blades have a flat shape, and they are exposed to wind stream in such a way that the wind forces are strictly perpendicular to the blade surfaces. This structure extracts more wind energy and minimizes the useless forces affecting shaft joints in traditional wind turbines. The ANSYS-based force analysis presented in this paper proves the advantage of using of protection shield in such windmill structure.
