The invention relates to a ducted turbofan (100) having: a nacelle (102) defining a flow passage (204) and including a fairing (216) that is translationally movable between an advanced position in which a window (220) is open between the flow passage (204) and the outside, and a retracted position in which the window (220) is closed between the flow passage (204) and the outside; transmission systems (223), each transmission system (223) comprising at least one arm (250) that is rotationally movable between a retracted position and an expanded position across the flow channel (204), where each transmission system (223) is translationally moved between an advanced position and a retracted position; a flexible barrier (252) for each arm (250), the flexible barrier being secured to the arm (250) and alternately occupying a folded position or an unfolded position; and an actuator (219) for each transmission system (223), the actuator being adapted to move the movable cowl (216), the transmission system (223) and each arm (250).

    本发明涉及一种涵道涡扇机(100),该涵道涡扇机具有:短舱(102),其界定流道(204)并包括在前进位置与缩回位置之间平移活动的整流罩(216),在前进位置中,窗口(220)敞开在流道(204)与外部之间;传动系统(223),每个传动系统(223)包括至少一个臂(250),臂在缩回位置与跨越流道(204)的张开位置之间旋转活动,其中,每个传动系统(223)在前进位置与缩回位置之间平移移动;对于每个臂(250)而言的柔性遮阻件(252),柔性遮阻件紧固到所述臂(250)并交替占据折叠位置或展开位置;以及对于每个传动系统(223)而言的致动器(219),致动器适于使活动整流罩(216)、传动系统(223)和每个臂(250)运动。
