Abstract

Un systeme de refroidissement ameliore de turbine a gaz pour une turbine a gaz modulaire est obtenu en montant une aube directionnelle creuse (18) sur un anneau de renforcement externe (32) pour s'etendre vers l'interieur vers un anneau de renforcement interne (36) dans lequel elles sont engagees de maniere coulissante. De l'air de refroidissement est achemine au travers d'un anneau spherique (24) dans les aubes directionnelles creuses (18) qui sont formees avec des trous d'event (56) sur leurs bords de fuite. Les deux parties d'anneau de renforcement externe (32) et interne (36) sont contenues dans l'un des modules moteurs (12) tandis que l'autre module moteur (14) est associe de maniere etanche au module (12) par des bagues d'etancheite (26, 28) ayant un plus grand coefficient d'expansion thermique que l'anneau de renforcement externe (32).
