Abstract

L’invention concerne une entrée d’air (12) pour une turbomachine d’aéronef, comprenant : un moyeu (60), une virole annulaire (70), et des bras (22) structuraux, caractérisée en ce que : le moyeu (60) comprend des premières rainures (61), la virole (70) comprend des secondes rainures (71) et les bras (22) comprennent à leurs extrémités radialement internes (22a) et externes (22b) des dispositifs de fixation (80a, 80b) par encliquetage élastique configurés pour coopérer avec des éléments complémentaires (62, 72) du moyeu (60) et de la virole (70), respectivement. L’invention concerne aussi une turbomachine d’aéronef, comportant une entrée d’air (12) telle que décrite précédemment et son procédé de maintenance comprenant une étape de démontage d’au moins une partie des bras (22), chacun de ces bras (22) étant démonté et retiré indépendamment des autres par translation du bras (22) dans une direction (D) parallèle à l’axe (18).
