Abstract

"INVERSOR DE EMPUXO COM BOCAL CONVERGENTE". Um inversor de empuxo (32) inclui capotas dianteira e traseira axialmente contíguas (34, 36) que definem uma nacela de ventilador para circundar um ventilador (16) e um motor de núcleo (14) com um conduto de ventilador (20) entre eles. A capota traseira (36) tem uma face dianteira (42) e a capota dianteira (34) tem uma face traseira (40) contíguas entre si, de modo a se definir um bocal de inversor (44), que converge em sentido radial para fora. A capota traseira (36) é trasladável entre uma posição de contenção, na qual o bocal do inversor está fechado, e uma posição de posicionamento, na qual o bocal do inversor está aberto para descarregar o ar do ventilador em uma direção para frente para inversão do empuxo.
