| description | Flame-holder device for afterburner of a turbofan, said turbofan comprising a first inner annular casing (3) and a second inner annular casing (5), these defining a passage (4) for a primary flow, and an outer annular casing (2) defining with said first inner annular casing (3) a passage (1) for a secondary flow, comprising at least one arm-supporting means (8) made of metallic material designed to be fixed to said outer casing (2) by means of an upper plate (9) and at least one flame-holder arm (7) that consists of a one-piece structure of composite material comprising two mutually attached walls (28a, 28b) arranged in such a way as to define a groove whose profile is approximately a V, said walls supporting, on their upper part situated in the secondary flow (31a, 31b), fixing means (34a, 34b) for fixing to said arm-supporting means (8), said device being characterized in that said upper parts (31a, 31b) are approximately planar and are positioned facing each other.
Dispositif accroche-flammes pour post-combustion d'un turboréacteur à double flux, ledit turboréacteur comprenant des premier (3) et second (5) carters annulaires internes, définissant un passage (4) pour un flux primaire, et un carter annulaire externe (2) définissant avec ledit premier carter annulaire interne (3) un passage (1) pour un flux secondaire, comportant au moins un support de bras (8) en matériau métallique destiné à être fixé audit carter externe (2) par l'intermédiaire d'une platine supérieure (9) et au moins un bras accroche-flammes (7) constitué par une structure monobloc en matériau composite comportant deux parois solidaires (28a, 28b) agencées de manière à définir une gorge présentant un profil sensiblement en V, lesdites parois portant sur leur partie haute située dans le flux secondaire (31a, 31b) des moyens de fixation (34a, 34b) sur ledit support de bras (8), caractérisé en ce que lesdites parties hautes (31a, 31b) sont sensiblement planes et positionnées en regard l'une de l'autre. |
