ELECTRICALLY DRIVEN DUCTED FAN ENGINE

The present invention relates to an electrically driven ducted fan engine (10), comprising a housing (12) with an inner housing wall (12a), defining a substantially cylindrical inner space (14) and a longitudinal axis (L), an inlet opening (16) provided in the housing (12), a rotor (20) with a multitude of rotor blades (20a), which is arranged to be driven in rotation by means of an electrical motor (22) and positioned in the inner space (14) of the housing (12) downstream of the inlet opening (16) with respect to the longitudinal axis (L) of the engine (10), a stator assembly (24) with a multitude of guide vanes (24a) extending from a radially central region of the inner space (14) to the inner wall (12a) of the housing (12), which is fixedly arranged in the inner space (14) of the housing (12) downstream of the rotor (20) with respect to the longitudinal axis (L) of the engine (10), and an exhaust opening (26) provided in the housing (12) downstream of the stator assembly (24) with respect to the longitudinal axis (L) of the engine (10), wherein with respect to the longitudinal axis (L) of the engine (10), an interstage region (30) is defined between the rotor (20) and the stator assembly (24), a guide vane region (32) is defined in the longitudinal section in which the guide vanes (24a) extend to the inner wall (12a) of the housing (12) and an exhaust section (34) is defined between the stator assembly (24) and the exhaust opening (26), wherein in at least one of the interstage region (30), the guide vane region (32) and the exhaust region (34), acoustic liners are provided to the housing (12).
