Abstract

L'invention concerne une turbine haute-pression (2) de turbomachine, comprenant un disque de rotor (6) centré sur un axe longitudinal (X-X) et sur lequel sont destinées à être montées des aubes de turbine (8), le disque comprenant une bride amont (18) destinée à être couplée en rotation autour d'une extrémité d'accouplement aval (20) d'un compresseur haute-pression de la turbomachine, un flasque d'étanchéité (10) disposé en amont du disque de rotor et portant des léchettes (12) d'un joint d'étanchéité à labyrinthe aval (14) destiné à réaliser une étanchéité avec un carter (16) de la turbomachine, et un disque de léchettes (32) monté sur la bride amont du disque de rotor et portant des léchetttes (34) d'un joint d'étanchéité à labyrinthe amont (36) destiné à réaliser une étanchéité radialement sous au moins un injecteur d'air de ventilation (26).
