Abstract

Le présent exposé concerne un ensemble pour turbine de turbomachine d’axe longitudinal (X) comprenant :- un cône d’éjection (102) comprenant une paroi annulaire externe (104) d’écoulement d’un flux d’air primaire et un caisson (108) agencé radialement à l’intérieur de ladite paroi annulaire externe, - un carter d’échappement agencé en amont du cône d’éjection (102), et - un organe de liaison (100) intercalé longitudinalement entre le carter d’échappement et le cône d’éjection, l’organe de liaison étant fixé au carter d’échappement et comprenant des premières pattes de fixation (112) flexibles distribuées circonférentiellement autour de l’axe longitudinal et des secondes pattes de fixation (114) flexibles distribuées circonférentiellement autour de l’axe longitudinal,dans lequel les premières pattes de fixation (112) sont reliées au cône d’éjection (102), et les secondes pattes de fixation (114)sont reliées au caisson (108). Figure à publier avec l’abrégé : [Fig. 2]
