Abstract

L’invention concerne un ensemble (10) pour turbomachine d’aéronef (1) d’axe longitudinal (X), l’ensemble (10) comprenant :- une virole cylindrique (931) de rotor destinée à être entrainée en rotation autour de l’axe longitudinal (X), - un distributeur (910) qui présente une couronne d’aubes de stator comportant un pied à l’extrémité radialement interne du distributeur, le pied portant un joint d’étanchéité (950) et le joint d’étanchéité (950) étant annulaire et configuré pour coopérer à étanchéité sans contact avec la virole cylindrique (931) disposée radialement sous le distributeur, dans lequel le distributeur (20) ou le joint d’étanchéité (50) comprend un système de butée (940) qui présente une excroissance de butée radiale ou axiale configurée pour entrer en butée directement ou indirectement avec la virole cylindrique (931), respectivement radialement ou axialement, afin de réaliser via l’excroissance de butée un freinage en rotation de la virole cylindrique (931).
