Abstract
Aube de turbine avec circuits de refroidissement améliorés Aube (114) de turbine, comprenant un corps d’aube (18) s’étendant selon une direction principale, une paroi intrados (24), une paroi extrados (26), un bord d’attaque (20) et un bord de fuite (22), l’aube (114) comprenant une pluralité de cavités internes (31) définissant un circuit de refroidissement primaire (131) de l’aube (114), un circuit de refroidissement secondaire (132), comprenant une pluralité de conduits internes (140), chacun desdits conduits internes (140) s’étendant au moins partiellement entre une cavité interne (31) du circuit de refroidissement primaire (131) et la paroi intrados (24), et entre la cavité interne (31) du circuit de refroidissement primaire (131) et la paroi extrados (26), de manière à au moins partiellement entourer une cavité interne (31) du circuit de refroidissement primaire (131), chacun desdits conduits internes (140) présentant une section inférieure ou égale à 2 mm. Turbomachine comprenant une telle aube (114). Figure pour l’abrégé : Fig. 3Turbine blade with improved cooling circuits Turbine blade (114), comprising a blade body (18) extending in a main direction, an intrados wall (24), an extrados wall (26), an edge of attack (20) and a trailing edge (22), the blade (114) comprising a plurality of internal cavities (31) defining a primary cooling circuit (131) of the blade (114), a secondary cooling circuit (132), comprising a plurality of internal conduits (140), each of said internal conduits (140) extending at least partially between an internal cavity (31) of the primary cooling circuit (131) and the intrados wall (24), and between the internal cavity (31) of the primary cooling circuit (131) and the extrados wall (26), so as to at least partially surround an internal cavity (31) of the primary cooling circuit (131), each of said internal conduits (140) having a section less than or equal to 2 mm. Turbomachine comprising such a blade (114). Figure for abstract: Fig. 3
