Title (EN) PLATFORM COOLING CIRCUIT WITH MATE FACE COOLING
(FR) CIRCUIT DE REFROIDISSEMENT DE PLATEFORME AVEC REFROIDISSEMENT DE FACE D'ACCOUPLEMENT
Abstract:
(EN) A turbine component (1) such as a blade or vane includes at least one platform (6) provided with a platform cooling circuit (30). The platform cooling circuit (30) includes an inlet (32) for receiving a coolant (K), and a cooling channel (40) formed within the platform (6) and connected to the inlet (32). The cooling channel (40) is positioned spaced from a mate face (22) of the platform and extends along at least a portion of the length of the mate face (22). Multiple outlet holes (70) are connected to the cooling channel (40), opening into the mate face (22). A rib (60) is positioned in the cooling channel (40) that divides a coolant flow through the cooling channel (40) into at least a first flow channel (40a) and a second flow channel (40b). The first (40a) and second (40b) flow channels are respectively connected to first (70a) and a second (70b) subset of the outlet holes (70).
(FR) Dans la présente invention, un composant de turbine (1) tel qu'une pale ou une aube comprend au moins une plateforme (6) pourvue d'un circuit de refroidissement de plateforme (30). Le circuit de refroidissement de plateforme (30) comprend une entrée (32) pour recevoir un fluide de refroidissement (K), et un canal de refroidissement (40) formé à l'intérieur de la plateforme (6) et relié à l'entrée (32). Le canal de refroidissement (40) est positionné à distance d'une face d'accouplement (22) de la plateforme et s'étend le long d'au moins une partie de la longueur de la face d'accouplement (22). De multiples trous de sortie (70) sont reliés au canal de refroidissement (40) et débouchent dans la face d'accouplement (22). Une nervure (60) est positionnée dans le canal de refroidissement (40) et divise un écoulement de liquide de refroidissement à travers le canal de refroidissement (40) en au moins un premier canal d'écoulement (40a) et un second canal d'écoulement (40b). Les premier (40a) et second (40b) canaux d'écoulement sont respectivement connectés à des premier (70a) et second (70b) sous-ensemble de trous de sortie (70).
