Title
(EN) MANUFACTURING OF SEGMENTED WIND TURBINE BLADE
(FR) FABRICATION D'UNE PALE D'ÉOLIENNE À SEGMENTS
Abstract
(EN)
The present invention relates to a method of manufacturing a wind turbine blade comprising the steps of manufacturing a pressure shell halves and arranging a spar structure (62) within one of the shell halves. The spar structure (62) comprises two parts releasably coupled to each other. The method results in a segmented wind turbine blade for easy transportation and re-assembly.
(FR)
La présente invention concerne un procédé de fabrication d'une pale d'éolienne comprenant les étapes de fabrication de moitiés de coque de pression et d'agencement d'une structure de longeron (62) à l'intérieur de l'une des moitiés de coque. La structure de longeron (62) comprend deux parties couplées de manière libérable l'une à l'autre. Le procédé permet d'obtenir une pale d'éolienne à segments permettant un transport et un ré-assemblage faciles.
