An engine nacelle (100) for an aircraft (10), has a fan housing; a fan housing movable between an advanced position and a retracted position, wherein at the retracted position, an opening between the bypass duct and the outside is opened; a flow guide secured to the mobile fan housing, wherein at the advanced position, the flow guide surrounds the fan housing and at the retracted position, the flow guide spans the opening; and a fan ramp (120) having a mounting base (122) and flaps (124), wherein the flaps are movable on the mounting base (122) between a stowed position and a deployed position, the fan ramp (120) has, for each flap (124), a restoring element (312) which urges the flap (124) into the deployed position, and the flow guide has a stop. The stop contacts the flap (124) when the mobile cowl passes from the retracted position through the reverse advanced position. Thus, at the advanced position, the flaps are folded rearward and their volume is reduced.
一种用于飞行器(10)的发动机短舱(100),具有风机壳体;能够在前进位置与缩回位置之间运动的风罩,缩回位置打开旁通管道与外部之间的开口;固定到移动式风罩的导流件,其中,在前进位置中,导流件围绕风机壳体,且其中,在缩回位置中,导流件跨过开口;以及具有安装基部(122)和襟翼(124)的风机斜面(120),翼襟能够在安装基部(122)上在收起位置与展开位置之间运动,其中,对于每个襟翼(124),风机斜面(120)具有复位元件(312),复位元件促使襟翼(124)进入展开位置,并且导流件具有止动件,当移动式风罩从缩回位置通过倒前进位置中时,止动件接触襟翼(124)。因此,在前进位置中,襟翼向后折叠,并且它们的体积减小。
