Abstract

Dispositif pratiquement insensible aux tolérances de construction. Chaque aube mobile de la turbine comporte dans sa plate-forme au moins un canal de distribution 28, s'étendant dans une direction parallèle à l'axe de rotation du rotor de la turbine, alimenté en agent de refroidissement par des canaux formés dans le pied de l'aube. Des encoches de déversement en V 64 sont formées le long de la partie radialement la plus intérieure du canal 28 pour distributer uniformément l'agent de refroidissement aux canaux d'agent de refroidissement de la plate-forme lesquels alimentent ensuite les canaux d'agent de refroidissement de la pale. Application aux moteurs à turbine à gaz à haute température.
