The invention relates to a turbofan engine. The turbofan engine comprises a motor and a nacelle and a duct between the nacelle and the motor. The nacelle includes a fixed structure, a movable assembly movable between an advanced position and a retracted position so as to define a window between the duct and the exterior, and a plurality of blades rotationally movable between a stowed position and a deployed position, each blade extending by a first arm and a second arm on either side of its axis of rotation, wherein, in the stowed position, the first arm is located outside the duct and the second arm is stowed within the nacelle, and, in the deployed position, the first arm spans the duct and the second arm extends from the nacelle. By means of such a vane, the air flow is optimally directed towards the front without having to provide a cascade. The invention also relates to an aircraft comprising at least one such turbofan engine.
本发明涉及一种涡轮风扇发动机,该涡轮风扇发动机包括马达和短舱以及在短舱和马达之间的管道。短舱包括固定结构体、活动组件以及多个叶片,该活动组件在前进位置和缩回位置之间活动以便在管道和外部之间限定窗口,这些叶片在收起位置和展开位置之间旋转地活动,每一个叶片通过第一臂和第二臂在其旋转轴线的两侧延伸,其中,在收起位置,第一臂位于管道的外部,并且第二臂收起在短舱内,在展开位置,第一臂横跨管道,并且第二臂从短舱伸出。通过这样的叶片,空气流被最佳地朝向前部引导,而不必设置叶栅。本发明还涉及包括至少一个上述涡轮风扇发动机的飞行器。
