An electrically driven ducted fan engine includes a housing, an inner wall of the housing defining a substantially cylindrical interior space and a longitudinal axis; an inlet opening; a rotor having a plurality of rotor blades positioned downstream of the inlet opening in the interior space of the housing relative to a longitudinal axis of the engine; a stator assembly fixedly arranged downstream of the rotor in the interior space of the housing with respect to a longitudinal axis of the engine; and an exhaust opening disposed in the housing downstream of the stator assembly with respect to a longitudinal axis of the engine; wherein, with respect to a longitudinal axis of the engine, an interstage region is defined between the rotor and the stator assembly, a guide vane region is defined in a longitudinal section in which the guide vanes extend to an inner wall of the housing, and an exhaust region is defined between the stator assembly and the exhaust opening, wherein in at least one of the interstage region, the guide vane region, and the exhaust region, an acoustic gasket is provided to the housing.

    一种电驱动涵道风扇发动机,包括:壳体,壳体内壁限定大致圆柱形的内部空间和纵向轴线;入口开口;转子,具有多个转子叶片,相对于发动机的纵向轴线在壳体的内部空间中定位在入口开口下游;定子组件,相对于发动机的纵向轴线在壳体的内部空间中固定地布置在转子下游;以及排气开口,相对于发动机的纵向轴线在壳体中设置在定子组件下游;其中相对于发动机的纵向轴线,级间区域限定在转子与定子组件之间,引导叶片区域限定在其中引导叶片延伸到壳体的内壁的纵向区段中,并且排气区域限定在定子组件与排气开口之间,其中在级间区域、引导叶片区域和排气区域中的至少一者中,声学衬垫设置到壳体。
