Title
(EN) TURBINE VANE HOLLOW INNER RAIL
(FR) RAIL INTÉRIEUR CREUX D'AUBE DE TURBINE
Abstract
(EN) The present invention relates to a guide vane device (100) for a turbine. The guide vane device (100) comprises an inner platform (101) with a through hole (301) forming a fluid channel for a cooling fluid, wherein the inner platform (101) extends in a circumferential direction (109) around a shaft (304) of the turbine. The guide vane device (100) further comprises a hollow aerofoil (102) with a cooling opening for exchanging the cooling fluid passing the through hole (301) into or from the hollow aerofoil (102), wherein the hollow aerofoil (102) is fixed to a first surface (201) of the inner platform (101). The guide vane device (100) further comprises a rail (103) comprising a recess (104) with a cooling fluid passage (105) forming a passage for the cooling fluid to the through hole (301), wherein the rail (103) is fixed to a second surface (106) of the inner platform (101) and the rail (103) extends along the second surface (106) in the circumferential direction (109) around the shaft (304). The cooling fluid passage (105) comprises in the circumferential direction (109) at least the dimension of the through hole (301).
(FR) La présente invention se rapporte à un dispositif d'aube de guidage (100) pour turbine. Le dispositif d'aube de guidage (100) comprend une plateforme intérieure (101) pourvue d'un trou débouchant (301) formant un canal de fluide destiné à un fluide de refroidissement, la plateforme intérieure (101) s'étendant dans une direction circonférentielle (109) autour d'un arbre (304) de la turbine. Le dispositif d'aube de guidage (100) comprend en outre une surface portante creuse (102) pourvue d'une ouverture de refroidissement pour échanger le fluide de refroidissement franchissant le trou débouchant (301) jusque dans la surface portante creuse (102) ou depuis celle-ci. La surface portance creuse (102) est fixée à une première surface (201) de la plateforme intérieure (101). Le dispositif d'aube de guidage (100) comprend en outre un rail (103) comprenant un évidement (104) pourvu d'un passage de fluide de refroidissement (105) formant un passage pour le fluide de refroidissement jusqu'au trou débouchant (301), le rail (103) étant fixé à une seconde surface (106) de la plateforme intérieure (101) et le rail (103) s'étendant le long de la seconde surface (106) dans la direction circonférentielle (109) autour de l'arbre (304). Le passage de fluide de refroidissement (105) comprend, dans la direction circonférentielle(109), au moins la dimension du trou débouchant (301).
