Title (EN) COMPOSITION AND METHOD FOR PREVENTION OF LEADING EDGE ERROSION IN WIND TURBINES
(FR) COMPOSITION ET PROCÉDÉ DE PRÉVENTION DE L'ÉROSION DE BORDS D'ATTAQUE DE PALES D'ÉOLIENNES
Abstract:
(EN) The present invention pertains to a layered structure intended to be used for protecting wind turbine blades against lead ing edge erosion. The layered structure is capable to resist the impact energy of incoming particles and/or rain drops and to damp the kinetic energy of such impacting object so that the covered structure does not suffer any negative effect upon the impact. The layered structure of the present invention is beneficial since, amongst other benefits, it reduces operating cost and wind turbine downtime. The present invention also provides a method for producing the layered structure of the present invention. It also pertains to the use of the layered structure of the present invention for protecting the leading edge of wind turbine blades against erosion.
(FR) La présente invention concerne une structure en couches destinée à être utilisée pour protéger des pales d'éoliennes contre l'érosion des bords d'attaque. La structure en couches peut résister à l'énergie d'impact de particules entrantes et/ou de gouttes de pluie et amortir l'énergie cinétique d'un tel objet percutant de sorte que la structure couverte ne subisse aucun effet négatif lors de l'impact. La structure en couches selon la présente invention est avantageuse puisque, entre autres avantages, elle réduit le coût de fonctionnement et le temps d'arrêt d'éoliennes. La présente invention concerne également un procédé de production de la structure en couches selon la présente invention. L'invention concerne également l'utilisation de la structure en couches selon la présente invention pour protéger le bord d'attaque des pales d'éoliennes contre l'érosion.
