The invention relates to a method for manufacturing a vane (1) to a gas turbine component, which vane is intended for guiding a gas flow, the vane (1) being produced by casting. An internal hole (3) for coolant is then cut out of the cast vane (1). The vane (1) is provided with a starter hole (5), either during casting or once casting is completed, following which the internal hole (3) for coolant is cut out of the vane, proceeding from the starter hole. The invention also relates to a method for manufacturing a gas turbine component comprising a plurality of vanes (1) for guiding a gas flow. The gas turbine component is cast in such a way that it comprises said vanes and an internal hole (3) for coolant is then cut out of each of the vanes in the manner stated above.
L'invention concerne un procédé de fabrication d'aube (1) de composant de turbine à gaz, ladite aube étant destinée à guider un écoulement gazeux, et étant produite par coulage. Un trou intérieur (3) destiné au passage d'un réfrigérant est ensuite découpé dans l'aube coulée (1). Un trou d'amorce (5) est d'abord ménagé dans ladite aube (1) soit au moment du coulage, soit après le coulage, puis le trou intérieur (3) destiné au passage du réfrigérant est découpé dans l'aube à partir dudit trou d'amorce. L'invention concerne également un procédé de fabrication de composant de turbine à gaz comprenant une pluralité d'aubes (1) destinées à guider un écoulement gazeux. Ledit composant de turbine à gaz est coulé de sorte qu'il comprenne lesdites aubes, et un trou intérieur destiné au passage du réfrigérant est ensuite découpé dans chaque aube selon le procédé précité.
