Title (EN) JOINT ASSEMBLY FOR A WIND TURBINE ROTOR BLADE
(FR) ENSEMBLE JOINT POUR UNE PALE DE ROTOR D'ÉOLIENNE
Abstract:
(EN) A joint assembly for joining rotor blade segments of a wind turbine rotor blade includes a female structural member secured within a first rotor blade segment. The female structural member includes first bore holes on opposing sides thereof that are aligned in a chord-wise direction. Further, the joint assembly includes a male structural member extending longitudinally from an end face of a second rotor blade segment. As such, the male structural member is received within the female structural member of the first rotor blade segment such that the first and second rotor blade segments are aligned and connected. The male structural member includes second bore holes on opposing sides thereof. Further, the second bore holes are aligned with the first bore holes. Moreover, the joint assembly includes at least one chord-wise extending pin extending through the first and second bore holes so as to join the first and second rotor blade segments. In addition, the male structural member has a height that increases from a blade root of the rotor blade towards the at least one chord-wise extending pin.
(FR) L'invention concerne un ensemble joint pour joindre des segments de pale de rotor d'une pale de rotor d'éolienne. L'ensemble joint comprend un élément de structure femelle fixé à l'intérieur d'un premier segment de pale de rotor. L'élément de structure femelle comprend des premiers trous d'alésage sur des côtés opposés de celui-ci qui sont alignés dans une direction de corde. En outre, l'ensemble joint comprend un élément de structure mâle s'étendant longitudinalement à partir d'une face d'extrémité d'un second segment de pale de rotor. Ainsi, l'élément de structure mâle est reçu à l'intérieur de l'élément de structure femelle du premier segment de pale de rotor de telle sorte que le premier et le second segment de pale de rotor soient alignés et reliés. L'élément de structure mâle comprend des seconds trous d'alésage sur des côtés opposés de celui-ci. En outre, les seconds trous d'alésage sont alignés avec les premiers trous d'alésage. De plus, l'ensemble joint comprend au moins une broche s'étendant dans le sens de la corde s'étendant à travers les premier et second trous d'alésage de façon à relier les premier et second segments de pale de rotor. De plus, l'élément de structure mâle a une hauteur qui augmente à partir d'un pied de pale de la pale de rotor vers l'au moins une broche s'étendant dans le sens de la corde.
