This patent concern a “Pale de rotor d’éolienne comportant un actionneur fluidique et procédé d’amélioration des performances aérodynamiques des éoliennes”. It was field as part of ASAPe project : “Add-on Systems for wind turbine performance improvement”.
The ASAPe project propose to develop a serie of original, robust and simple ADD-ON system, composed of E-penon sensors and/or wireless pressure sensors as well as fluidic actuators of pulsed jet type, capable of dynamically adapting wind turbine blade aerodynamic and thus to decrease aerodynamic loads. This system will be progressively brought to maturity by using a bidimensional blade profile in the aerodynamic wind tunnel of LHEEA lab. (gust at an intermediate scale) and the Jules Verne wind tunnel of CSTB (fluctuating wind at full scale). At full scale, a real wind turbine blade profile will be provided by industrials who have signed a support letter for this projet (EDF-EN and VALOREM). Also, a prospectif work will be conducted to prepare wind field test (choice of the site, the wind turbine type, the position and control strategy …).
This project is a WEAMEC project with the funding from the Pays de la Loire Region.
This project is coordinated by the LHEEA (Research Laboratory in Hydrodynamics, Energy and Atmospheric Environment). The LHEEA is a Centrale Nantes/CNRS mixed research unit (UMR 6598).
