The front of the blade is referred to as the leading edge and the back is referred to as the trailing edge, as illustrated in Figure 1a. Figure 1 Air Moving Past a Turbine. . The performance, efficiency, and lifespan of a wind turbine largely depend on its blade design and construction. The aerodynamics behind blades are not simple; they are closer to aircraft wings. . The blades are the turbine's “catchers' mitt. A poor blade design means wasted wind, higher stress on components, and lower energy output. On an airplane wing, the top surface is rounded, while the other surface is relatively flat. . The tower stands 80 meters tall, and that's not including the blades, which make it taller still. It is an upright, cylindrical structure, several meters in diameter, tapering as its height increases. This is the most common modern tower.
