Abstract

Un turboréacteur (1) s'étendant selon un axe longitudinal et comprenant une virole intérieure et une virole extérieure (4) délimitant une veine secondaire (Vs) pour la circulation d'un flux d'air secondaire, le turboréacteur (1) comprenant au moins une ailette (5) dans la veine secondaire (Vs) fixée d'une part à la virole intérieure et d'autre part à la virole extérieure (4), la virole extérieure (4) comprenant au moins une ouverture de montage (41) s'étendant radialement par rapport à l'axe, le turboréacteur (1) comprend au moins une pièce de liaison (6) positionnée dans l'ouverture de montage (41) qui comprend au moins un organe élastique (7), en contact avec la virole extérieure (4), configuré pour se déformer selon la direction radiale de manière à rattraper un jeu radial (Aj) entre la virole extérieure (4) et l'ailette (5).A turbojet (1) extending along a longitudinal axis and comprising an inner shell and an outer shell (4) delimiting a secondary stream (Vs) for the circulation of a secondary air flow, the turbojet (1) comprising at the at least one fin (5) in the secondary stream (Vs) fixed on the one hand to the inner shell and on the other hand to the outer shell (4), the outer shell (4) comprising at least one mounting opening (41 ) extending radially with respect to the axis, the turbojet (1) comprises at least one connecting piece (6) positioned in the mounting opening (41) which comprises at least one elastic member (7), in contact with the outer shell (4), configured to deform in the radial direction so as to take up a radial play (Aj) between the outer shell (4) and the fin (5).
