Abstract

L'invention concerne une pale de rotor destinée à une éolienne. Cette pale comprend deux demi-coques qui s'étendent du pied de pale au bout de pale dans la direction longitudinale de la pale et sont assemblées le long de leur périphérie, ainsi qu'au moins un dispositif de liaison disposé entre les demi-coques et relié à celles-ci, ce système de liaison présentant deux éléments de liaison comportant chacun deux branches de liaison et une traverse reliant ces deux branches de liaison. Selon l'invention, sur chaque élément de liaison, les extrémités des branches de liaison sont reliées à une demi-coque correspondante et les traverses des éléments de liaison sont reliées entre elles.
