Abstract

Turbine haute-pression (10) d'une turbomachine, comprenant au moins un distributeur (16) et une roue (18) montée rotative à l'intérieur de secteurs d'anneau (20) fixés à un support annulaire (24) qui est suspendu à un carter externe (22), le distributeur comprenant à son extrémité radialement interne des moyens de fixation sur un carter interne et à son extrémité radialement externe des moyens (102, 104) d'appui axial sur un élément fixe (90) de la turbine qui est suspendu au carter externe indépendamment du support annulaire de fixation des secteurs d'anneau.

Figure imgaf001
High-pressure turbine (10) of a turbomachine, comprising at least one distributor (16) and a wheel (18) rotatably mounted inside ring sectors (20) fixed to an annular support (24) which is suspended on an outer casing (22), the distributor comprising at its radially inner end fixing means on an inner casing and at its radially outer end means (102, 104) of axial support on a fixed element (90) of the turbine which is suspended from the outer casing independently of the annular support for fixing the ring sectors.
