The invention relates to a novel type of casing (10) for a compressor that is resistant to titanium fire (burning titanium). The invention comprises making a mixed casing (10) in which the fixed blade carrying structure (2) comprises a unitary part made of titanium or a titanium alloy and at least one shield-forming member (12, 120, 121, 122) made of one or more refractory alloys and which is incombustible to titanium fire, the shield(s) being connected to the unitary part by a connection means (13, 130) arranged with the shield(s) so as to form together the inner wall defining the outer contour (40) of the compressor jet (4).
L' invention concerne un nouveau type de carter (10) de compresseur résistant au feu de titane (titane en combustion). Selon l'invention, on réalise un carter (10) mixte dans lequel la structure porteuse d' aubes fixes (2) est constituée par une pièce monobloc (11) en titane ou alliage de titane et au moins un élément formant bouclier (12, 120, 121, 122) en alliage (s) réfractaire (s) et incombustible au titane en combustion, le (s) bouclier (s) étant solidarisé (s) à la pièce monobloc par des moyens de fixation(13, 130), ces derniers étant agencés avec le (s) bouclier (s) de manière à définir ensemble la paroi interne délimitant le contour externe (40) de la veine (4) du compresseur.
