Abstract

bocal de fluxo frio de um tubo reator de fluxo de duplo com fluxos separados que incorpora um inversor de empuxo com grades, a presente invenção é relativa a um bocal de fluxo frio de um tuboreator de fluxo duplo com fluxos separados que compreende um elemento de capô anelar (27, 127, 227) móvel em translação axial entre uma posição retraída à montante para um funcionamento do motor em empuxo direto e uma posição de extensão à jusante, e um inversor de empuxo com grades (28, 128, 228) em forma de setores de anel cilíndrico coaxiais com o dito elemento de capô, constituidos de aletas de orientação radial e espaçadas axialmente de posição de extensão a jusante de ditas passagens radiais através das grades de inversão de empuxo. a tubulação é caracteriazada pelo fato que o raio dos setores de anel que formam as grades (28, 128, 228) não é constante ao longo da circunferência do elemento de capô (27, 127, 227) e por o dito elemento de capô anelar (27, 127, 227) compreende uma parede interior (27int, 127int, 227int) que delimita a periferia da veia de fluxo frio e uma parede interior (27ext, 127ext, 227ext) de envoltória da carlinga, o raio dos cortes transversais de pelo menos uma das paredes não sendo constante quando se desloca ao longo da circunferência do elemento de capô, os cortes sendo realizados entre a borda à montante do elemento de capô e sua borda de jusante.
