Zusammenfassung:	"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. A method for replacing a portion of a gas turbine engine rotor blade, the rotor blade having a contour defined by a blade first sidewall (70) and a blade second sidewall (70) includes cutting through the rotor blade such that a cut line (110) extends from a leading edge (74) of the blade to a trailing edge (76) of the blade, and between the first sidewall and the second sidewall, removing the portion of the rotor blade that is radially outward of the cut line, and coupling a replacement blade portion (120) to remaining blade portion (98) such that the newly formed rotor blade (150) is formed with a predetermined aerodynamic contour.
