Today's wind turbine blades, which can measure more than 60 metres in length, are subjected to enormous loads, which means that a blade can flex as much as 4-6 metres during strong gusts. However, the blades are also so long that there can be considerable differences in the loading from the gusts along the blade. In wind farms, surrounding wind turbines also exert considerable influence and generate turbulence, which has a more localised effect.
