Wind System Towers

As discussed in Chapters 2 and 3ยป it is often best to support your windsystem, be it vertical-axis or horizontal-axis, to capture the higher winds above the ground and to be well above the nearest trees. Supporting a wind turbine that weighs several hundred pounds is no simple task and requires a rigid structure of some sort. Towers are subjected to two types of loads, as illustrated in Figure 5-44: weight, which compresses the tower downward, and drag, which tries to bend the tower downwind.

Towers are made in two basic configurations: guy-wire supported, and cantilever or unsupported (sometimes called freestanding) (Fig. 5-45). Also, given these two basic structural support configurations, towers are made with telephone poles, pipes (Fig. 5-46), or other single column structures, as well as lattice frameworks of pipe (Fig. 5-47), or wooden boards.

Regardless of which tower design you select, the overriding consideration is the selection of a tower that can support the wind turbine you '.elect in the highest wind possible at your site. Of course, cost must ?l30 be considered. The load that causes man>
