Abstract
Un élément d'écartement (64) définit un compartiment intermédiaire (66) pour l'air de refroidissement, entre les disques (16, 34). L'air de refroidissement provenant d'un compartiment (31) en amont du premier disque (16) est dirigé vers l'aval, en passant par les passages dans les rainures de talon d'aubes, ensuite radialement vers l'intérieur dans le compartiment intermédiaire (66), d'où il s'écoule radialement vers l'extérieur, ensuite axialement dans les passages pour l'air de refroidissement dans les rainures de talon d'aubes du second disque (34).
