Abstract

La présente invention vise à améliorer la liaison entre une virole et un carter de turbomachine d’aéronef. L’invention propose donc une virole acoustique 27 et une enveloppe 29 de carter 23, ainsi qu’un procédé d’assemblage de turbomachine améliorés. Un système de liaison par bandes auto-agrippantes est prévu pour fixer de manière détachable la virole acoustique 27 à l’enveloppe 29. Figure pour l'abrégé : Figure 4
