Title (EN) DEVICE AND METHOD FOR HEATING AND DEICING WIND ENERGY TURBINE BLADES
(FR) DISPOSITIF ET PROCEDE DE CHAUFFAGE ET DEGIVRAGE D'AUBES D'EOLIENNE
Abstract:
(EN) The invention relates to heatable wind energy turbine blades and to a method of heating and deicing the turbine blades using conductive fabrics to displace and/or cease the buildup of ice on the turbine blades by electrothermal fabric heater disposed or integrated on the turbines for effectively deicing the blades. Multiple turbine blade design methods are explored as well as heater materials and the application of such materials.
(FR) Cette invention se rapporte à des aubes d'éolienne qui peuvent être chauffées et à un procédé de chauffage et dégivrage faisant usage de tissus conducteurs pour déplacer et/ou stopper l'accumulation de givre sur les aubes des turbines au moyen d'un dispositif de chauffage des tissus électrothermiques disposé sur les turbines ou intégré à celles-ci en vue du dégivrage effectif des aubes. Cette invention se rapporte à de multiples procédés de conception d'aubes de turbines ainsi qu'à des matériaux chauffants et à l'application de tels matériaux.
