Physics of Wind Energy, and the area through which it is passing. Conversion of wind power to rotation of turbine depends on the geometry of the blades with respect to the incoming wind velocity vector. The rotation of blades is governed by the basic principles of aerodynamics. The ratio of the circumferential velocity of

Design Considerations,one with gear box, upwind or downwind operation—are available when a decision on the specifications of a wind energy converter is taken. These different design options are compared in this chapter. A modern trend is to use large size horizontal axis upwind machines that usually have three blades and
