We can say that a wind system transforms wing energy of the air mass to a mechanical power, characterized by the speed of rotation and mechanical torque. In our case the turbine is formed with a horizontal axis, the principle of wind conversion was established by Betz it assumes that the blades are placed in a lively air to infinity upstream speed 1 V and downstream of an infinite speed 2 V with an air mass moving through the density ρ with surface S of the blades
