Abstract: A data evaluation system, in particular for data evaluation on interfaces on board an aircraft, includes a data processing server having a receiver device, a data processing processor and an external server interface, and includes multiple data readers, coupled to the data processing server via the receiver device, that each have a device processor and a data capture component connected to the device processor and are configured to forward data captured by the data capture component to the data processing server for conditioning.

Abstract: An energy supply network, especially for an aircraft or spacecraft, including a first coupling device, the first coupling device being configured to couple the energy supply network to an external energy source, a first high voltage direct current, HVDC, segment, the first HVDC segment being coupled to the first coupling device and a second HVDC segment, the second HVDC segment being coupled to the first coupling device. Also provided is a corresponding method and an aircraft or spacecraft incorporating such an energy supply network.

Abstract: An energy supply network for an aircraft or spacecraft, comprising at least one energy generating device for generating electrical energy, comprising at least two energy control devices, at least one of which is coupled directly to at least one of the energy generating devices and which are adapted each to provide a controlled supply voltage so as to supply electrical loads located in the aircraft with energy, and comprising a high-voltage direct current transmission device, which couples the at least two energy control devices to one another by means of high-voltage direct current transmission. Further, a method for supplying energy, and an aircraft or spacecraft.
