Abstract

L'invention concerne une structure de support pour le moyen d'étanchéité entourant les ailettes du rotor d'un moteur à turbine à gaz comportant un carter refroidissable et un dispositif pour attacher le moyen d'étanchéité comportant plusieurs segments. Pour attacher le moyen d'étanchéité au carter, plusieurs segments de support avant et plusieurs segments de support arrière sont prévus. Chaque segment de support est fixé en un seul point au carter. Chaque segment de support avant contacte l'extrémité avant d'au moins un segment du moyen d'étanchéité et chaque segment de support arrière contacte l'extrémité arrière d au moins un segment du moyen d'étanchéité. Application aux turboréacteurs.
