Abstract

Une coque de pale d'éolienne comprend : une partie coque interne comprenant un matériau composite renforcé par des fibres ; une partie coque externe ; un élément chauffant électrothermique intégré à l'intérieur de la coque de pale ; et une ligne électrique métallique qui est reliée à l'élément chauffant électrothermique au niveau d'une borne. La ligne électrique métallique est conçue pour transporter l'énergie électrique vers l'élément chauffant électrothermique par l'intermédiaire de la borne. La ligne d'alimentation métallique est prise en sandwich entre les parties coques interne et externe.
