The tower is divided into 9 segments of varying diameters, wall thicknesses, and inclination angles, as shown in Figure 2. Table I summarizes the dimensions of each segment.

What are the guidelines for a wind turbine?

The complete list of guidelines is provided below. Modern wind turbines use large turntable bearings at the root of each blade to enable pitch angle changes and thus aerodynamic performance and load control. Yaw bearings are used for angular realignment of the nacelle into the predominant wind direction.
