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).A spacer (64) defines an intermediate compartment (66) for cooling air between the discs (16, 34). The cooling air coming from a compartment (31) upstream of the first disc (16) is directed downstream, passing through the passages in the blade heel grooves, then radially inwards in the intermediate compartment (66), from which it flows radially outwards, then axially in the passages for the cooling air in the heel grooves of the blades of the second disc (34).
