Abstract

"PROCESSO PARA ALTERAçãO DA EXTENSãO DE UM JATO COERENTE". Trata-se de um processo para alteração da extensão de um jato coerente mediante o estabelecimento de um jato coerente utilizando um envelope de chama gerado com utilização de combustível gasoso e alteração da taxa de fluxo do combustível gasoso, preferencialmente utilizando um gás inerte para composição com o mesmo para manter uma taxa de fluxo total constante de combustível e gás inerte.
