Abstract

Ensemble (7) rotatif pour turbomachine, qui comprend - un disque (8) pourvu d'alvéoles (10) et d'une lèvre (14) en saillie formant crochet ; - une pluralité d'aubes (9) pourvues chacune d'un pied (20) engagé axialement dans un alvéole (10) ; - un flasque (23) annulaire dans lequel est emboîtée la lèvre (14) ; - un jonc (31) intercalé entre le disque (8) et le flasque (23), le jonc (31) ayant une portée (32) tronconique en contact avec le flasque (23) et étant mobile entre : ○ une position radialement rétractée, dans laquelle il permet au flasque (23) d'occuper une position droite, et ○ une position radialement déployée, dans laquelle le jonc (31) force le flasque (23) à occuper une position basculée dans laquelle un bord (25) externe de celui-ci fait contact avec un becquet (18) d'aube (8), - des moyens de verrouillage du jonc (31) en position radialement déployée.
