Abstract

La présente invention porte sur un carter (20) annulaire de turboréacteur multiflux comprenant un premier élément (22) formant moyeu, un second élément (24) formant enveloppe cylindrique, radialement externe et concentrique au premier élément, des bras (23) radiaux reliant le premier élément (22) au second élément (24), au moins une partie desdits bras étant structuraux et ayant un profil aérodynamique d'aubage redresseur de flux, caractérisé par le fait qu'il comprend un premier secteur (20C) d'anneau du carter et un second secteur (20T) d'anneau, le premier secteur d'anneau étant réalisé en matériau composite et le second secteur d'anneau en métal, lesdits bras (23T) radiaux du second secteur (20T) d'anneau étant structuraux.
