Abstract

a invenção se refere a um dispositivo para reduzir ruído de jato de um motor de turbina, compreendendo uma capota externa (16) provida dentro de uma parede (20) definindo no exterior uma seção anular (22) para o fluxo de uma corrente secundária do motor de turbina, a dita parede da capota externa compreendendo uma pluralidade de circuitos de microjatos (28) cada compreendendo meios (30) para gás de amostra fluir na seção de fluxo na corrente secundária que se abre em um conduto de alimentação (32) único, que por sua vez se abre em uma borda posterior da capota externa através da pelo menos uma grade de ejeção (34) capaz de dividir a corrente de amostra de gás em uma pluralidade de correntes de gás tendo seções diretas com dimensões menores que uma seção direta (d) de um conduto de alimentação.
