(EN) IMPROVEMENTS RELATING TO WIND TURBINE BLADE MANUFACTURE
(FR) AMÉLIORATIONS APPORTÉES À LA FABRICATION DUNE PALE D'ÉOLIENNE
Abstract
(EN)
A method of making a wind turbine blade (10) having a shear web (20, 22) bonded between first and second half shells (16, 18) is described. The method involves providing a web locator (40) on an inner surface of a half shell. The web locator has a fixed portion (42) and a spring portion (44) extending from the fixed portion. The spring portion is moveable relative to the fixed portion between compressed and relaxed states.
(FR)
L'invention concerne un procédé de fabrication d'une pale d'éolienne (10) comprenant une âme de cisaillement (20, 22) liée entre des première et seconde demi-coques (16, 18). Le procédé consiste à disposer un dispositif de positionnement d'âme (40) sur une surface interne d'une demi-coque. Le dispositif de positionnement d'âme comporte une partie fixe (42) et une partie ressort (44) s'étendant à partir de la partie fixe. La partie ressort est mobile par rapport à la partie fixe entre un état comprimé et un état relâché.
