As wind turbines get larger and larger—a 5 MW turbine has a blade about 180′ long, which at its height is over 400′ off the ground—the different types wind stress on the turbine can be of such a nature that components can wear out early, causing early breakdown of the turbine. Moog Japan Ltd has created a system that can detect the stress on each blade of the turbine and adjust them to reduce stress due to variations in wind strength:…
