Abstract

L'invention concerne un capot d'entrée tournant pour turbomachine. Le capot comprend un cône (3), une virole (4) et un bouchon (8). Le bouchon (8) comprend une paroi externe (92) présentant une surface externe (S2) qui est destinée à former un profil aérodynamique en continuité avec une surface extérieure (S1) d'une paroi extérieure (30) du cône, lorsque la paroi externe (92) obture une cavité (37) qui est formée entre la paroi extérieure (30) du cône et la virole (4). Le bouchon (8) comprend une paroi interne de support (98) et un organe de fixation (7). L'organe de fixation (7) est configuré pour traverser la paroi de support (98) et pour solidariser rigidement la paroi de support (98) à une paroi intérieure (31, 35) du cône et simultanément la paroi intérieure (31, 35) du cône à la virole (4), à travers un orifice (91) de la paroi externe.
