Abstract

Est concerné un rotor de turbomachine à gaz pour aéronef, comprenant un disque (48) et au moins une masselotte (85) d'équilibrage du disque. Le disque présente une partie saillante vers l’amont définissant une virole annulaire (79) festonnée présentant ainsi une alternance de dents (81) saillante vers l’amont et de creux (83) vers l’aval. La masselotte (85) d'équilibrage s’étend dans un dit creux et est fixée à la virole annulaire. Figure à publier avec l’abrégé : Figure 5
