(FR) PROCÉDÉ DE FABRICATION D'UN CARTER ANNULAIRE ÉQUIPE DE TURBOMACHINE
Abstract: front page image
(EN)The invention relates to a method for manufacturing a carrying casing (12) provided with a collar (18) for supporting at least one cartridge of abradable material for a turbomachine, said carrying casing (12) comprising at least one bare annular casing (16) and one block of honeycomb material (20) that comprises an outer face (22) configured to be secured to an inner face (24) of said bare annular casing (16), said block being covered with a skin (26), characterized in that it comprises successively: – a step in which the outer face (22) of the block (20) is secured to the inner face (24) of the bare annular casing (16), – a step in which the circularity of an inner face (32) of the block (20) is monitored and in which, if necessary, the inner face (32) of the block (20) is machined to round, – a step in which, simultaneously, said skin (26) is produced and is secured to said block (20).
(FR)L'invention concerne un procédé de fabrication d'un carter porteur (12) muni d'une virole (18) de support d'au moins une cartouche de matériau abradable pour une turbomachine, ledit carter porteur (12) comportant au moins un carter annulaire nu (16) et un bloc de matériau en nid d'abeilles (20) qui comporte une face externe (22) configurée pour être fixée à une face interne (24) dudit carter annulaire nu (16) ledit bloc étant recouvert d'une peau (26), caractérisé en ce qu'il comporte successivement : - une étape au cours de laquelle on fixe la face externe (22) du bloc (20) sur la face interne (24) du carter annulaire nu (16), - une étape au cours de laquelle contrôle la circularité d'une face interne (32) du bloc (20) et au cours de laquelle, le cas échéant, on usine au rond ladite face interne (32) du bloc (20), - une étape au cours de laquelle, simultanément, on fabrique ladite peau (26) et on la fixe audit bloc (20).
