Abstract

um núcleo cerâmico usado para a produção de uma pá de turbina oca de uma turbomáquina pelo método de fundição por cera perdida e conformado para constituir as cavidades da referida pá em um único componente, compreendendo, de modo a abastecer juntamente o interior das referidas cavidades com ar de resfriamento, as porções de núcleo (60, 62) destinadas para formar a primeiro e a segundas cavidades laterais conectadas a uma porção de núcleo (48) destinada a formar pelo menos uma cavidade central, no pé do núcleo (54) por pelo menos duas junções cerâmicas (70) como também em diferentes alturas do referido núcleo por um pluralidade de outras junções cerâmicas (64, 66, 68), cujo posicionamento define a espessura das divisórias internas da pá, enquanto assegura um complemento de ar de resfriamento para as zonas críticas predeterminadas das primeira e segunda cavidades laterais.
