The invention relates to a fixed vane assembly for a turbine engine that comprises a vaulted casing (18) and at least two angular sectors (8.1) defining a high-pressure turbine distributor, each angular sector (8.1) including a fastening tab (22) for fastening the angular sector (8.1) onto the casing (18), wherein the fixed vane assembly includes a ring of abradable material (28) attached onto the casing (18) on the side of a mobile vane assembly by a plurality of screw-nut assemblies (30), the fixed vane assembly further including radial retention pins (36) for the angular sectors (8.1) that are inserted into first bores formed in the fastening tabs (22) and in the mounting flange (34), said bores having axes substantially parallel to the longitudinal axis (X), the mounting flange (34) being attached onto the casing (18) by the same screw-nut assemblies (30) as those used for attaching the carrier of the abradable material ring on the casing (18).
Aubage fixe de turbomachine comportant un carter sous chambre (18) et au moins deux secteurs angulaires (8.1) formant un distributeur haute pression, chaque secteur angulaire (8.1) comportant une patte de fixation (22) du secteur angulaire (8.1) sur le carter (18), l'aubage fixe comportant un anneau d' abradable (28) fixé sur le carter (18) du côté d'un aubage mobile au moyen d'une pluralité d'ensemble vis-écrou (30), l'aubage fixe comportant également des pions de retenue radiale (36) des secteurs angulaires (8.1) introduits dans des premiers alésages pratiqués dans les pattes de fixation (22) et dans la bride de montage (34), lesdits alésages ayant des axes sensiblement parallèles à l'axe longitudinal (X), la bride de montage (34) étant fixée sur le carter (18) par les mêmes ensembles vis-écrous (30) que ceux fixant le support d'anneau d'abradable sur le carter (18).
