Abstract

Dispositif de refroidissement de la partie externe d'un disque de turbine (2) au moyen d'un courant d'air frais externe (circuit II) sans mélange avec la ventilation plus chaude du centre du disque (circuit I). Une pièce (30) traversée de canaux (31, 32) qui se croisent sans se couper permet d'éviter le mélange de courants sensiblement perpendiculaires devant une partie (22) du disque (2) et un mélange qui réduit l'efficacité du refroidissement.
