Title (EN) IMPROVED ELECTRO-THERMAL HEATING
(FR) CHAUFFAGE ÉLECTROTHERMIQUE AMÉLIORÉ
Abstract: front page image
(EN)Examples of the present disclosure generally relate to wind turbine blades configured to minimize or eliminate buildup of ice on the blades. In order to maintain an ice free surface on a wind turbine blade, a plurality of ETH panels are embedded in the wind turbine blade to heat the wind turbine blade. Two or more ETH panels of the plurality of ETH panels are overlapping in order to provide a predetermined heat flux over a region covered by the two or more ETH panels.
(FR)Des exemples de la présente invention concernent d'une manière générale des pales d'éolienne conçues pour réduire au minimum ou éliminer l'accumulation de glace sur les pales. Afin de maintenir une surface exempte de glace sur une pale d'éolienne, une pluralité de panneaux ETH sont intégrés dans la pale d'éolienne pour chauffer la pale d'éolienne. Au moins deux panneaux ETH de la pluralité de panneaux ETH se chevauchent afin de fournir un flux thermique prédéterminé sur une région recouverte par lesdits panneaux ETH.
