Abstract

L’invention concerne un carter (10) de turbomachine d’aéronef, comportant :- une paroi (11) sensiblement cylindrique, s'étendant suivant un axe longitudinal,- une virole (12) annulaire d'isolation acoustique montée radialement à l'intérieur de ladite paroi et sensiblement coaxiale à ladite paroi,- et des organes (13) de fixation amovible de la virole à l’intérieur dudit carter, ces organes étant répartis autour dudit axe et dans un espace annulaire (E) s’étendant entre la virole et la paroi,caractérisé en ce que lesdits organes comportent chacun un corps monobloc présentant :- une première portion (131) de liaison à la virole,- une seconde portion (132) de liaison au carter, et- une portion intermédiaire (133) de liaison des première et seconde portions de liaison formant un angle supérieur à 90° avec chacune desdites première et seconde portions.
