Abstract

Turboréacteur (1), comportant une soufflante (2), au moins un carter (11) annulaire entourant ladite soufflante (2), des éléments (15, 17) étant fixés au carter par l’intermédiaire d’un ensemble de fixation comprenant : - au moins un support (19) s’étendant axialement, chaque support comportant une première extrémité (31) et une seconde extrémité (33), - une pluralité d’organes d’attache (21), d’attache assurant la fixation des éléments au support. L’ensemble de fixation comprend en outre : - un premier élément élastique (23), agencé pour solliciter la première extrémité du support à l’écart du carter et un premier élément de rappel (27) agencé pour solliciter élastiquement la première extrémité vers le carter, et - un deuxième élément élastique (25), agencé pour solliciter la seconde extrémité du support à l’écart du carter et un deuxième élément de rappel (29) agencé pour solliciter élastiquement la deuxième extrémité vers le carter.
