20130134916 | CONTROLLING AN ELECTRICAL CONSUMER OF AN AIRCRAFT - An electrical consumer of an aircraft comprises an electric motor and an inverter for producing an alternating voltage for the electric motor. A method for controlling the electrical consumer comprises determining a rotational frequency for the electric motor. The method also includes establishing whether the rotational frequency leads to oscillations in the input current of the inverter which are below a predefined threshold, the oscillations being produced by the inverter when producing a supply voltage for the electric motor, and changing the rotational frequency if it has been established that the rotational frequency leads to oscillations below the predefined threshold. | 05-30-2013 |
20130154357 | ELECTRICAL SYSTEM FOR AN AIRCRAFT - An electrical system for an aircraft is provided. The system comprises an inverter for transforming a first alternating current from an on-board network having a variable frequency into a second alternating current, and at least a first electrical load and at least a second electrical load, which are configured to be operated simultaneously by the second alternating current. | 06-20-2013 |
20140084951 | METHOD FOR DETECTING A DEVICE THAT GENERATES SPURIOUS SIGNALS IN AN ELECTRICAL NETWORK, AN ELECTRICAL SYSTEM AND AN AIRCRAFT - A method for detecting a device that generates spurious signals in an electrical network, to which several devices and at least one fault detection device are connected, includes the steps of monitoring the electrical network for electrical spurious signals, sequentially deactivating each device for a predetermined time T when an electrical spurious signal has been detected, and checking the electrical network for the disappearance of the respective spurious signal, and signaling as soon as the respective spurious signal has disappeared upon deactivating a respective device. This makes it possible to especially reliably detect a device in an electrical network that couples an undesired spurious signal into the network. | 03-27-2014 |
20140094103 | PARTITION - A collapsible partition is provided having a collapsed configuration and an installed configuration in which it is arranged to divide a vehicle compartment into two parts. The partition includes, but is not limited to a ducted portion comprising a duct. The duct extends within the partition from a first opening at a first end of the duct to a second opening at a second end of the duct. The duct is arranged to convey a control fluid for controlling the heat transfer between the partition and at least one of the two parts of the vehicle compartment. There is also disclosed a vehicle compartment control arrangement and a method of partitioning a vehicle compartment. | 04-03-2014 |
20140104732 | SUPPLY SYSTEM FOR AN AIRCRAFT, USE OF A SHIELDED SUPPLY LINE IN AN AIRCRAFT AND AN AIRCRAFT WITH A SUPPLY SYSTEM - A supply system for supplying energy in an aircraft includes at least one electrical line including at least one core connectable to a pole of a current source, an electrically conductive shield, and a detection unit having at least two electrical inputs. The shield surrounds the at least one core under a distance and creates an intermediate space between the at least one core and the shield. At least one port of the detection unit is connected to the at least one core. At least another port of the detection unit is connected to at least one of the shield and the at least one core. The detection unit is adapted for detecting a differential current over the at least one core or an absolute current between the shield and a ground potential for generating a warning signal if a predetermined threshold value for the detected current value is exceeded. | 04-17-2014 |
