Abstract
"MéTODO PARA ESTENDER UMA BORDA DE FUGA DE UMA ALTA DE BOCAL DE TURBINA A GáS E MéTODO PARA ESTABELECER UMA áREA DE GARGANTA FINAL DE UMA ESTRUTURA CIRCUNFERENCIAL DE BOCAL DE TURBINA A GáS". A presente invenção refere-se a uma área de garganta final de uma estrutura circunferencial de bocal de turbina a gás estabelecida pelo fornecimento de pelo menos duas aletas de bocal de turbina a gás (42), e pela determinação de uma área de garganta inicial no modo de pares entre cada par de aletas de bocal de turbina a gás (42). Para cada par de aletas de bocal de turbina a gás (42) cuja área de garganta inicial no modo de pares não esteja dentro da faixa alvo de área de garganta no modo de pares final, uma borda de fuga (50) de pelo menos uma das aletas de bocal de turbina a gás (42) é estendido em resposta à etapa de determinação da área de garganta no modo de pares inicial, de modo que uma área de garganta no modo de pares final esteja dentro de uma faixa alvo de área de garganta no modo de pares final. Uma pluralidade de pares de aletas de bocal do bocal de turbina a gás (42) que juntas compreendem a estrutura circunferencial de bocal de turbina a gás pode ser selecionada de modo que a soma de suas áreas de garganta no modo de pares final esteja dentro de uma faixa alvo de área de garganta total final. A borda de fuga (50) pode ser estendida para este ou outros propósitos pela fixação de um fio de extensão (100) na borda de fuga (50) que se estende no sentido do comprimento ao longo da borda de fuga (50), aplicando um material de brazagem (104) no fio de extensão (100) e na borda de fuga (50), e aquecendo o material de brazagem (104) até uma temperatura de brazagem para fundir pelo menos uma porção do material de brazagem (104) e, quando do resfriamento, aderir o fio de extensão (100) e o material de brazagem (104) na borda de fuga (50).
