horizontal rotor windmills

windmills. This book deals only with the design of rotors for horizontal axis windmills, which are rotors with the axis of rotation in line with the wind velocity. The rotor rotates because forces are acting on the blades. These forces are acting on the blades because the

Figure 1 is a toy windmill with a shaft seat fixed to the windmill pole and a hub in front of the shaft seat. The two are connected by a windmill shaft, and the hub is free to rotate around the windmill shaft.

HAWTs utilize aerodynamic blades (i.e. airfoils) fitted to a rotor, which can be positioned either upwind or downwind. HAWTs are typically either two- or three-bladed and operate at high blade tip speeds.

Windmills seen on many farms and ranches throughout the U.S. were developed in the 1860's (lorry 1976). These windmills have a horizontal-axis rotor, often called head-on machines, meaning that the axis of rotation is parallel to the direction of the wind. Railroads were one of the early users of windmills to fill water tanks for locomotives. Ranchers
