Title
(EN) JOINTED WIND TURBINE BLADE WITH NOISE REDUCTION TAPE
(FR) PALE D'ÉOLIENNE ARTICULÉE AVEC BANDE DE RÉDUCTION DE BRUIT
Abstract
(EN)
A jointed wind turbine rotor blade (28) includes a first blade segment (30) and a second blade segment (32) extending in opposite directions from a chord-wise joint line (34). Each of the blade segments (30, 32) includes a pressure side shell member (31) and a suction side shell member (33). A sealing tape (100) is applied over the shell members (31, 33) so as to bridge across the chord-wise joint line (34). The sealing tape (100) includes side edges (102) that are aligned parallel with airflow (104) over the shell members (31, 33) at the chord-wise joint line (34) at a defined load and operational condition on the jointed wind turbine blade (28).
(FR)
L'invention concerne une pale de rotor d'éolienne articulée (28) comprenant un premier segment de pale (30) et un second segment de pale (32) s'étendant dans des directions opposées de part et d'autre de la ligne articulaire de corde (34). Chacun des segments de pale (30, 32) comprend un élément de coque côté pression (31) et un élément de coque côté aspiration (33). Une bande d'étanchéité (100) est appliquée sur les éléments de coque (31, 33) de manière à former un pont à travers la ligne articulaire de corde (34). La bande d'étanchéité (100) comprend des bords latéraux (102) qui sont alignés parallèlement à l'écoulement d'air (104) sur les éléments de coque (31, 33) au niveau de la ligne articulaire de corde (34) à un état de charge et opérationnel défini sur la pale d'éolienne articulée (28).
