Abstract
Rotor dont les aubes sont refroidies proportionnellement à leur température. Il comporte un dispositif d'alimentation des aubes en liquide de refroidissement qui comprend : une bride 32 partant radialement de l'arbre 18 et contiguë au disque 20, un passage dans l'arbre, orienté axialement et comprenant au voisinage de la bride des ouvertures 47, et un dispositif dans le disque pour faire passer le liquide de refroidissement de la bride aux canaux 38 de la jante extérieure. Application aux turbines à gaz.
