Abstract

nacela para um motor turbojato de fluxo dual de aeronave a invenção refere-se a uma nacela para um motor turbojato, incluindo uma seção a montante formando uma aba de entrada de ar e definindo um espaço (10) para a circulação de um fluxo de ar principal (12). a nacela inclui um dispositivo (100) para modular a seção transversal do espaço (10), compreendendo: meio (102) para injetar um fluxo auxiliar (104) de um gás por meio de um efeito ejetor induzido; meio de sucção (106) para atrair o fluxo auxiliar injetado (112); e uma área de retorno (108) de fluxo auxiliar interno (109) em uma ou mais paredes (110), referida área sendo configurada para permitir a circulação da porção do fluxo auxiliar injetado (104) e do fluxo auxiliar atraído (112) e para trazer parte do fluxo auxiliar injetado (104) em contato com o fluxo de ar principal (12). a invenção é caracterizada pelo fato de que a área de retorno interna inclui uma parte frontal externa formando uma área em que a espessura da área de retorno interna é reduzida.
