Abstract[English]
A root extender 24 for extending the length of a wind turbine blade 16 is described. The root extender 24 is positioned between a root end 20 of the blade 16 and a mounting structure 26 of a hub 18, such as a pitch bearing or hub flange. The root extender 24 comprises a plurality of pipes 30. Elongate tension elements 48 extend through the respective pipes 30 to connect the blade to the mounting structure 26. The pipes 30 are held in compression between the root end 20 of the blade 16 and the mounting structure 26.[French]
L'invention concerne un prolongateur de racine (24) permettant d'étendre la longueur d'une pale d'éolienne (16). Le prolongateur de racine (24) est positionné entre une extrémité de racine (20) de la pale (16) et une structure de montage (26) d'un moyeu (18), tel qu'un palier de pas ou une bride de moyeu. Le prolongateur de racine (24) comprend une pluralité de tuyaux (30). Des éléments de tension allongés (48) s'étendent à travers les tuyaux respectifs (30) pour relier la pale à la structure de montage (26). Les tuyaux (30) sont maintenus en compression entre l'extrémité de racine (20) de la pale (16) et la structure de montage (26).
