  • Patent number: 12005775
    Abstract: A valve device for a fuel tank of a motor vehicle includes, for example, a housing having a tank connection for connecting the valve device to a vent line going to or coming from the fuel tank, and a filter connection for connecting the valve device to a vent line going to or coming from an activated charcoal filter. The tank connection and the filter connection are fluidically connected to one another inside the housing through a vent duct. A valve is arranged inside the housing for opening and at least partially closing the vent duct, wherein the valve has a valve element that is movably mounted between an opening position and a closed position inside the housing along a longitudinal axis of the housing. An actuating element is accessible from outside the valve device, which is movably mounted along the longitudinal axis inside the housing and motion-coupled in such a way with the valve element that a movement of the actuating element in a closing direction moves the valve element in closing direction.

  • Patent number: 11989037
    Abstract: A method for controlling a aircraft with a plurality of drive units, in particular a plurality of electrical drive units, and a controller for flight control. At least one lateral control signal is entered into the controller for flight control in order to initiate a lateral movement of the aircraft. The significant point is that a speed (V) of the aircraft is ascertained through a speed estimation (6) and, depending on the estimated airspeed (V), a commanded roll angle (?C) and a commanded pitch angle (?c), a rate of turn ({dot over (?)}) is calculated. The lateral movement is automatically initiated with the calculated rate of turn ({dot over (?)}) through input of the lateral control signal.

  • Patent number: 11983017
    Abstract: A method for determining a maneuvering reserve in an aircraft having a number of propulsion units, preferably a multirotor VTOL aircraft, most preferably an aircraft with electrically operated drive units for the rotors, including the steps: a) Determining a control vector, ?, for the aircraft, ?=(L M N F)T, the components of which represent control torques of the aircraft around the roll axis, L, the pitch axis, M, and the yaw axis, N, and a total thrust, F, b) Approximating an existing four-dimensional control volume, D, of the aircraft by a four-dimensional ellipsoid, E, the axes of which represent the control torques, L, M, N, of the aircraft and the total thrust, F, c) Determining a normalized control vector, ?ind=(Lind Mind Nind Find)T for the aircraft, using axis dimensions, Lmax, Mmax, Nmax, Fmax, of the ellipsoid, in particular semi-axis dimensions of the ellipsoid; and d) Outputting at least the normalized control vector, ?ind, for determining a permissible flight maneuver in at least one dimension
