The invention relates to a rotor blade in a wind energy plant, comprising at least one recess arranged in the area of the base (6) of the rotor blade and extending substantially perpendicular to the longitudinal axis of said rotor blade (6) to accommodate a cross-bolt (16,18) which can be joined to a traction element (20,22) to enable connection of the rotor blade (6) to a rotor hub (11) in a wind energy plant (1). The invention further relates to a rotor for a wind energy plant, comprising a rotor hub (11) and at least one rotor blade (6) secured to said hub (11), in addition to a wind energy plant. The invention is characterized in that the recess only partially crosses through the rotor blade.
L'invention concerne une pale de rotor destinée à une éolienne, comportant au moins un évidement disposé dans la région de la base (6) de la pale de rotor et s'étendant sensiblement perpendiculairement à l'axe longitudinal de la pale de rotor (6), cet évidement étant destiné à recevoir un axe transversal (16, 18) s'accouplant avec un élément de traction (20, 22) pour permettre le raccordement de la pale de rotor (6) à un moyeu de rotor (11) d'une éolienne (1). L'invention concerne également un rotor destiné à une éolienne et muni d'un moyeu (11) et d'au moins une pale (6) fixée sur ce moyeu (11), ainsi qu'une éolienne. L'invention est caractérisée en ce que l'évidement ne traverse que partiellement la pale de rotor.
