A ducted fan of an aircraft includes a rotor-side fan and a stator-side duct that surrounds the rotor-side fan radially at the outside and defines a flow channel for air flowing via the fan. The stator-side duct has an inner wall that faces toward the rotor-side fan and which is perforated at least in certain sections. The stator-side duct has an outer wall that faces away from the fan. Between the inner wall and the outer wall of the stator-side duct, there are formed cavities which, forming sound-deadening resonators, are coupled via the perforated inner wall to the flow channel for the air flowing via the rotor-side fan. The cavities are filled, in a region which faces away from the inner wall and thus faces toward the outer wall, with activated carbon.
