Abstract: 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.

Abstract: A method for interconnecting cell stacks of a battery module in a battery. In the battery module, the cell stacks are arranged in a battery module housing. In each case two cell stacks are arranged next to one another and form a cell stack group, and the two cell stack groups are arranged behind one another.

The two cell stacks of the first cell stack group are electrically interconnected via at least one opening arranged in a wall of the battery module housing. The two cell stacks of the second cell stack group are inserted into the battery module housing. Electrically interconnecting the two cell stacks of the second cell stack group to each one of the two cell stacks of the first cell stack group.

Abstract: A method of controlling a hydraulic actuator of an active spring damper element in a vehicle for damping a relative movement between a vehicle structure and a wheel suspension. A hydraulic arrangement is provided for controlling the hydraulic actuator, which includes a hydraulic pump and at least one control valve. In a first method step, a relative movement between the vehicle structure and wheel suspension is detected. A force to be provided by the hydraulic actuator and a volume flow to be provided by the hydraulic pump are determined based on the detected relative movement. Then, a speed of the hydraulic pump is set to provide the volume flow required for the position of the force.

Abstract: A damping arrangement of an active chassis for an axle of a motor vehicle, wherein a damping system cooperates with each wheel of the axle. Each of the damping systems includes a damper having a double-acting hydraulic cylinder and a piston. The damper is couplable to a wheel suspension system of the respective wheel. A hydraulic pump and an electric motor drives the respective hydraulic pump, wherein the hydraulic pump is driven by the electric motor in different directions of rotation to provide different conveying directions. A hydraulic unit includes a hydraulic reservoir and valves, wherein the hydraulic pump and the hydraulic unit of the respective damping system cooperate with hydraulic chambers of the hydraulic cylinder of the respective damping system, such that, depending on the conveying direction of the hydraulic pump, a movement of the piston in either a first or second actuation direction can be provided.

Abstract: A method for operating a damper system of a vehicle having an active damper and a hydraulic assembly arranged to control the damper. The hydraulic assembly includes a hydraulic pump and at least one control valve. Requirements placed upon the damper are defined with regard to the dynamics and force that are to be set. Depending on the defined requirements, the hydraulic pump of the hydraulic assembly operates at a minimum rotary speed and a defined opening setting of the at least one control valve. Based on the minimum rotary speed of the hydraulic pump and the defined opening settings of the control valve, a dynamic force setting of the damper takes place by way of a change of the opening setting of the at least one control valve. Alternatively or additionally, a high-value force setting of the damper takes place by changing the rotary speed of the pump.
