Abstract

"TUBEIRA CONFLUENTE DE ESCAPE". Descreve-se uma tubeira de escape de motor de turbina a gás (38), que inclui uma nacela (16) tendo uma entrada (32) e saída principal (46) nas extremidades opostas, e um duto principal (36) estendendo-se entre elas. Um duto secundário de derivação (48) se estende radialmente através da nacela (16) a montante da saída principal (46) e inclui uma entrada secundária (50) desobstruída, unida ao duto principal (36), e uma saída secundária (52) envolvendo a saída principal (46) para descarga coletiva do fluxo de escape em correntes confluentes.
