Abstract: In a system and a method for pressure management while extracting a liquid from a liquid storage vessel, a liquid and its vapor are provided in liquid storage vessel. The liquid is extracted by a pump from the storage vessel and fed as a liquid flow to a consumer unit. A defined partial flow is separated from the liquid flow downstream of the pump. The pressure of the partial flow is reduced by a pressure regulation means and the partial flow is evaporated by an evaporator. The evaporated partial flow is fed back into the storage vessel.

Abstract: A method for repairing a damaged aircraft fuselage outer skin part, the damaged skin part comprising a static pressure port around which is arranged a stopper fastened to a structure of the fuselage at which a pipe of the static pressure port opens, the method including removing the stopper from the static port, fitting a patch including an opening for housing the stopper, and re-fitting the stopper on an adjustable-thickness spacer. A repair assembly configured to apply the repair method is also provided. Advantageously, it is thus possible to recreate an aerodynamic profile in accordance with the requirements for taking static pressure of the aircraft, with a reduced down-time of the aircraft.

Abstract: An aircraft propulsion assembly includes a power unit, a nacelle positioned around the power unit, and a cleaning device configured to remove insect residue and in order to maintain optimal aerodynamic characteristics. This cleaning device is configured to spread at least a cleaning liquid over an exterior and forward region of the air intake of the nacelle, the cleaning liquid being entrained by a high-speed airflow generated by the power unit and acting as a high-pressure water jet to encourage the removal of the insect residue.

Abstract: The DC electrical network comprises an electrical load supplied with electricity by an electrical power source to which the electrical load is linked by a first electrical line and a second electrical line. An overcurrent protection system comprising an input pole and an output pole is mounted in series on the first electrical line. The overcurrent protection system comprises an electronic switch mounted in series between the input pole and the output pole, an electrical current sensor, and a controller configured to control the electronic switch. It also comprises an electronic device linked to the input pole and to the second electrical line. The controller is configured to command a conducting state of the electronic device when a current measurement from the electrical current sensor is above a predetermined current threshold, then to command an opening of the electronic switch.

Abstract: A connection assembly between two portions of a line including an inner conduit for transporting a cryogenic fluid, the assembly including two flanges which are respectively arranged at the ends of the line portions and which are configured to be held in contact with one another by virtue of a fixing arrangement. The contact zone between the two flanges includes at least two grooves for positioning seals and at least one conduit opening out, for the one part, between the two seals and, for the other part, into an expansion chamber for the cryogenic fluid. The expansion chamber is arranged in one, or in the vicinity of one, of the first connection flange and the second connection flange. The expansion chamber includes a detector for detecting the presence of the cryogenic fluid in the expansion chamber or a recess configured for the installation of such a detector.

Abstract: A hold of an aircraft includes at least two system cabinets, one cabinet is disposed longitudinally. The longitudinal cabinet is movable between a use position along a wall of the fuselage and a maintenance position, in which it is spaced apart from the wall of the fuselage. This arrangement makes it easier to access the system cabinets installed in the hold of the aircraft by the operators arranging the hold or carrying out maintenance on the cabinets.

Abstract: A resistive skin element for an acoustic panel intended for an aircraft includes a first ply, a second ply with openings and a wire mesh which is sandwiched between the two plies. First ply includes at least one layer made of C/PEAK and a film made of PEI. Second ply includes at least one layer made of PEI First ply is crossed by perforations. Second ply has openings configured so that second ply does not obstruct the perforations of first ply. The wire mesh allows perforations with large sizes to be made while keeping good acoustic properties.
