Abstract

L’invention concerne un rotor dont un disque aubagé monobloc pourvu d’au moins une masselotte (170) d'équilibrage. La partie amont de la plateforme du disque présente une bride (72). La bride (72) s’étend annulairement autour dudit axe (X) et définit, avec une surface radialement intérieure (66c) de la plate-forme, au moins un dit logement (73). La masselotte (170) d'équilibrage est fixée à la bride, en porte-à-faux. Figure à publier avec l’abrégé : Figure 4The invention relates to a rotor including a one-piece bladed disc provided with at least one balancing weight (170). The upstream portion of the disk platform has a flange (72). The flange (72) extends annularly around said axis (X) and defines, together with a radially inner surface (66c) of the platform, at least one said housing (73). The balancing weight (170) is fixed to the flange, cantilevered. Figure to be published with abstract: Figure 4
