Abstract

La présente invention concerne un procédé de liaison pour une pale d'éolienne, et une pale d'éolienne. Le procédé de liaison comprend les étapes consistant à : monter une première plaque de bande et une seconde plaque de bande dans un ensemble plaque de bande intégrée à l'avance ; lier des premiers blocs d'entretoise d'espace à une bride supérieure et à une bride inférieure de la première plaque de bande respectivement, et lier des seconds blocs d'entretoise d'espace à une bride supérieure et à une bride inférieure de la seconde plaque de bande respectivement ; fournir une première demi-coque supportée par un premier demi-moule et une seconde demi-coque supportée par un second demi-moule ; lever l'ensemble plaque de bande ; revêtir des bords avant et arrière de la première demi-coque, des positions de liaison et l'ensemble plaque de bande avec un adhésif ; et chauffer et durcir l'adhésif à chaque emplacement pour lier la première demi-coque, la seconde demi-coque et l'ensemble plaque de bande dans une pale de turbine éolienne entière. Le procédé de liaison en une étape de la présente invention présente une fiabilité élevée et une faible intensité de travail, et la pale d'éolienne présente un cycle de moulage court.
