Title (EN) TURBINE BLADE MANUFACTURING METHOD
(FR) PROCÉDÉ DE FABRICATION D'AUBE DE TURBINE
Abstract: front page image
(EN)A method for manufacturing a turbine blade (1), is provided. The method comprises the following steps: - producing a shell and core assembly by additive manufacturing process, the shell and core assembly defining at least one internal cavity and having an internal structure corresponding to at least one internal cooling circuit of the turbine blade; - pouring molten metal in the internal cavity of the shell and core assembly; - solidifying the metal; - removing the shell and core assembly.
(FR)L'invention concerne un procédé de fabrication d'une aube 1 de turbine. Le procédé comprend les étapes suivantes, consistant à : - produire un assemblage d'enveloppe-noyau par un procédé de fabrication additive, l'assemblage d'enveloppe-noyau définissant au moins une cavité interne et présentant une structure interne correspondant à au moins un circuit de refroidissement interne de l'aube de turbine; - verser du métal fondu dans la cavité interne de l'assemblage d'enveloppe-noyau; - solidifier le métal; - enlever l'assemblage d'enveloppe-noyau.
