Active Flap Systems Coming Closer to Market
The idea of active flap systems on wind turbine blades is to reduce the variable loading on the blades by continuously adjusting the shape of the trailing edge of the blade to counteract the fluctuating loads from the wind. The reduction in loading means that a larger rotor can be mounted on the same turbine platform and the power production can be increased. In this way the cost of energy (COE) can be reduced, which is the overall goal with the new smart blade control.
