Video : Wind Turbine Yaw Movements and Gyroscopic Forces Under normal operational conditions, yaw movement may occur when the rotor is stopped or when it is turning. When the rotor is stopped, the force applied by the yaw drive needs to overcome only the inertia of the nacelle and the frictional forces at the yaw…

Why on earth do all wind turbines have exactly three blades? ship propellers can manage with two – and one would immediately think that 4 or 5 blades would catch even more wind and therefore provide even more power. The 3-blade horizontal axis wind turbine is the most advantageous option, in several technical and operational…

Wind turbines have a service life of about 20 to 25 years, after which they need to be replaced with newer and more efficient models. This means that there is a growing amount of old and obsolete wind turbines that need to be disposed of. While most of the components of a wind turbine, such…

Wind turbine blades are remarkable feats of engineering, transforming the power of the wind into clean electricity. The materials they are made from and the methods used to construct them have a profound impact on their power output, longevity, and overall sustainability. The ideal blade is made from strong yet lightweight materials that can withstand…
