The wind upstream of the wind turbine rotor is highly unsteady and inhomogeneous (misalignment of the rotor in the wind, turbulence of the atmosphere, gust … etc) while blade are increasingly longer. Using Add-ons (systems installed a posteriori) on the blade for a dynamic adaptation of the aerodynamics to prevent load fluctuations is foreseen to be a significant improvement to increase wind turbine lifetime.
This project will be realized with the equipment acquired as part of the ROTOR-OPTIM project.
Scientific advances and innovation
Sensor and actuator add-ons for a dynamic adaptation of the blade aerodynamics.
Expected technical and economic impact
New add-ons that can be used on wind turbine blades.
