Abstract

"MéTODO DE REPARO DAS PALHETAS DE UM ROTOR DE UMA TURBINA A GáS". Um método de substituição de uma parte (90) de uma palheta (50) de rotor de um motor de turbina a gás, a palheta de rotor apresentando um contorno definido pela primeira parede lateral (70) da palheta e pela segunda parede lateral (72) da palheta, dito método compreendendo cortar através da palheta de rotor de tal forma que se estenda uma linha de corte (110) do bordo de ataque (74) da palheta até o bordo de fuga (76) da palheta e entre a primeira parede lateral e a segunda parede lateral; remover a parte da palheta de rotor que está radialmente para fora da linha de corte; e acoplar uma parte de palheta de substituição (120) na parte remanescente (98) da palheta, de tal forma que a nova palheta de rotor formada (150) seja formada com um contorno aerodinâmico predeterminado.
