Abstract

Un procédé de régulation de la température interne des aubes d'une roue à aubes comprenant un circuit d'alimentation en gaz de refroidissement et une pluralité d'aubes (100, 700, 800, 900) comportant chacune une paroi intrados (108) et une paroi extrados (110) formant un corps (102) creux comprenant un ensemble de refroidissement doté de cavités de refroidissement (128 à 144) définies par des premières cloisons (112 à 122) s'étendant entre les parois intrados et extrados (108 et 110) et des secondes cloisons (124 et 126) s'étendant entre deux premières cloisons (112 et 114, 116 et 118). L'ensemble de refroidissement de chaque aube (100, 700, 800, 900) comprend en outre au moins une cavité de régulation (150) de la température interne de l'aube (100, 700, 800, 900) séparée des parois intrados et extrados (108 et 110), le procédé comprenant une alimentation de ladite au moins une cavité de régulation (150) par un flux de gaz de refroidissement dont la température en entrée de la cavité de régulation (150) est supérieure à la température la plus basse des flux de gaz de refroidissement alimentant les cavités de refroidissement (128 à 144).
