Abstract
La présente invention concerne un tube d'éjection pour un tube central de ventilation d'une turbomachine, Le tube d’éjection comprend au moins une patte d'appui apte à assurer le contact du tube d’éjection à l’intérieur du tube central de ventilation. La patte comprend une languette libre fixée à une extrémité du tube d’éjection par une base de la languette La base de la languette s'étend parallèlement à une direction axiale du tube de façon à ce que la languette soit orientée le long d'une circonférence du tube d’éjection. L'invention comprend aussi un tube central de ventilation avec le tube d'éjection et une turbomachine avec ledit tube central de ventilation. L'invention concerne également un procédé de montage du tube central de ventilation. Le tube d'éjection est introduit à l'intérieur du tube central de ventilation en tournant le tube d’éjection par rapport au tube central de ventilation, de préférence selon une direction de rotation telle que, vue du tube central de ventilation, la base de la languette devance la languette. Figure pour l’abrégé : Figure 3.
