Title (EN) COOLED TURBINE VANE
(FR) AUBE REFROIDIE DE TURBINE
Abstract:
(EN) The invention relates to a turbomachine turbine vane comprising a root having a blade (12) comprising a leading edge (16) and a trailing edge (17) and a lower surface wall (14) and an upper surface wall (13), as well as: a manifold for cooling (18) the leading edge (16); a supply line (19) for collecting air from the root and supplying the manifold (18); a side cavity (23) extending along the upper surface wall (13) and supplied with air from the root, to form a heat shield facing the supply line (19); and a circuit forming a trombone comprising a middle portion (24) extending along the supply line (19) and extending laterally to the upper surface wall (13), said middle portion (24) being supplied by the supply line at the tip of the blade (12).
(FR) L'invention a pour objet une aube de turbine de turbomachine comprenant un pied portant une pale (12) comprenant un bord d'attaque (16) et un bord de fuite (17) et une paroi d'intrados (14) et une paroi d'extrados (13), ainsi que : –une rampe de refroidissement (18) du bord d'attaque (16); –un conduit d'alimentation (19) pour collecter de l'air au niveau du pied et alimenter la rampe (18); –une cavité latérale (23) longeant la paroi d'extrados (13) et alimentée en air depuis le pied, pour former un écran thermique en regard du conduit d'alimentation (19); –un circuit formant trombone comprenant une portion médiane(24) longeant le conduit d'alimentation (19) et s'étendant latéralement jusqu'à la paroi d'extrados (13), cette portion médiane (24) étant alimentée par le conduit d'alimentation au niveau du sommet de la pale (12).
