Abstract

L'invention concerne une aube creuse de distributeur de turbine à gaz en forme de caloduc, contenant une vapeur condensable telle que du sodium dont le transfert des parties froides aux parties chaudes de l'aube, et inversement, est facilité par la présence, sur les parois internes de la cavité intérieure de l'aube, d'une double couche de treillis en acier inoxydable 21 et 22 de diamètre de fils différent, de façon à réduire au minimum les différences de température entre les diverses parties de l'aube. Le dispositif s'applique également aux bandages ou anneaux d'étanchéité des turbines à gaz.
