Abstract: A process for connecting two aircraft fuselage segments and a reinforcing profile arranged in the joint region of the two aircraft fuselage segments by friction twist welding using a rotating tool, wherein a cover plate is brought onto the aircraft fuselage segments to be connected above the joint regions and after the friction twist welding the remainder of the cover plate is milled off. This makes it possible to overcome significantly greater gap tolerances in the edges to be connected so that the dimension tolerance requirements for the aircraft fuselage segments can be reduced. Furthermore, a smooth surface can be achieved in the welding region.

Abstract: An icing protection system comprises a fuel cell, an evaporative cooling system, a thermal deicing device, a control unit and a device for measuring the pressure in the evaporative cooling system. The evaporative cooling system is in thermal contact with the fuel cell and with the thermal deicing device in order to conduct heat from the fuel cell to the thermal deicing device. The control unit controls the electrical power demanded from the evaporatively cooled fuel cell in dependence on a deviation of the pressure measured by the pressure measuring device from a predetermined NOMINAL pressure. In this way, an energetically very efficient and very well controllable icing protection system is made available that can be operated without bleed air supplied by engines or electrical energy provided by engine generators.

Abstract: Detection and location of electrical faults in a network of metal structures which can receive electric cables and allow return of current by the cables. The reflectometry-based method involves injecting a probe signal into a cable coupled to the structures and analyzing the signal reflected by the anomalies. A conductive element is provided for carrying the probe signal at a constant distance from each structure. In one aspect, an insulated conductive element is arranged inside the metal structure and is built into a longitudinal groove in a surface for receiving a longitudinal plastic holder wedged into the structure. The reflected signal from the conductive element is compared to a threshold above which an anomaly is detected, and the anomaly is located by topological correlation. The invention is useful for airplane raceways having a composite skin.
