(FR) AUBE A CALAGE VARIABLE POUR ETAGE DE REDRESSEUR, COMPRENANT UNE PLATEFORME INTERNE NON CIRCULAIRE
Abstract:
(EN) The invention relates to a variable setting vane (8) for a rectifier stage, including a blade (43) on either side of which are provided a radially inner platform (13) and a radially outer platform, the blade (43) having a surface (64) defining a suction side and a surface (62) defining a pressure side and separating the platform (13) into a portion (13a) arranged on the suction side and a portion (13b) arranged on the pressure side. According to the invention, and following the direction of the vane rotational axis (20), the portion (13a) has an outer outline (Ca) vertically adjacent to a circle (C1), remote from which and inside which at least a portion (Cb1) of the outer outline (Cb) of the portion (13b) of the platform (13) is located.
(FR) La présente invention se rapporte à une aube (8) à calage variable pour étage de redresseur, comprenant une pale (43) de part et d'autre de laquelle sont disposées une plateforme radialement interne (13) et une plateforme radialement externe, la pale (43), qui présente une surface (64) formant extrados ainsi qu'une surface (62) formant intrados, séparant la plateforme (13) en une partie (13a) agencée du côté extrados et une partie (13b) agencée du côté intrados. Selon l'invention, en vue prise selon la direction de l'axe de rotation d'aube (20), la partie (13a) présente un contour extérieur (Ca) superposé à un cercle (C1), à distance et à l'intérieur duquel se trouve au moins une partie (Cb1) du contour extérieur (Cb) de la partie (13b) de la plateforme (13).
