    Abstract: A turbofan engine with a nacelle and a flow path, in which the nacelle comprises a movable cowl that makes it possible to define a window between the flow path and the outside, veils with a first edge fixed to the movable cowl and alternately assuming a folded position or a deployed position across the flow path, and a pneumatic system displacing a second edge of the veils from the folded position to the deployed position and vice versa. The pneumatic system comprises a rigid main roll, for each veil, at least one extendable secondary roll fixed to a second edge of the veil, and a pressurization and depressurization system which, alternately, generates a pressure or a depression in each secondary roll. Replacing the reverse doors and their driving mechanisms with flexible veils and a pneumatic system allows for a weight reduction.

    Abstract: A system comprising a trolley which comprises a platform and wheels attached beneath the platform, an air intake of an aircraft engine, where the air intake rests on the platform so as to have its narrowest part at the top and its widest part at the bottom, and an inflatable protection item in the form of a closed envelope which is placed around the widest part of the air intake. A system of this kind makes it possible to protect the air intake from collisions that it might experience during movement of the trolley, and to increase safety by avoiding collisions between operators and the air intake.

    Abstract: An assembly forming an acoustic insulator having a first sheet, a pierced second sheet, and a plurality of first and second structures. Each first structure comprises a first and a second strip, wherein each is shaped to form half of the wall of a cage and wherein, for two successive halves, each strip comprises a facet of a joining wall. Each second structure is made up of a first and a second strip, wherein each is shaped to form half of the wall of a cone, wherein. For each strip, at least one of the wall halves of each cone is pierced. For two successive halves, each strip comprises one facet of the connecting wall. Each cone is located in a cell and each connecting wall is located between the two facets of a joining wall, and, between two adjacent first structures, a second structure is likewise fitted.

    Abstract: A transport trolley for transporting a load comprising a base mounted on motorized wheels, a deck mounted to be translationally mobile on the base in a direction of translation, a first motorized system displacing the deck, a hexapod platform comprising a platform and a set of six jacks in which each is mounted articulated between the deck and the platform. The platform comprises a plurality of bearing points configured to come under the load and each bearing point takes the form of a receptacle with its opening oriented upwards. A control unit controls each motorized wheel, the first motorized system and each jack. The use of a hexapod platform makes it possible to finely position the wing at its position of fixing onto the fuselage and the use of a mobile deck supporting the hexapod platform allows for adjustability of the position despite a smaller footprint around the aircraft.

    Abstract: A system for assisting in the landing of an aircraft including a processing unit configured to: during a first phase of a landing runway approach procedure, when the aircraft flies above a predetermined height with respect to a landing runway threshold, determine a bias of position and speed information from an inertia unit of the aircraft, as a function of the merged position and speed information determined as a function of information from a receiver of ILS guidance signals and of information from a signal receiver of a satellite navigation system, then, during a second phase of the approach procedure, when the aircraft flies below the predetermined height, determine so-called adjusted aircraft position and speed information by applying, to information from the inertial unit, a correction corresponding to the bias determined during the first phase of the approach procedure.

    Abstract: An aircraft having an engine, a cabin, an air conditioning system collecting the hot air from the engine, so as to treat the hot air, regulate a temperature of the hot air and send the hot air towards the cabin via a main line, an air line channeling the air leaving the cabin, and an arrangement for cooling the engine using the air thus drawn off by the air line. By drawing off the air at the outlet of the cabin, the performance of the engine is improved and the fuel consumption is reduced.

    Abstract: A device includes a current difference measurement module for measuring the difference between a current flowing in a positive contact of the electrical installation and a current flowing in a negative contact of the electrical installation, a low-pass filter for filtering the differential current, a full-wave rectifier without threshold module for rectifying the filtered current and a trip module for emitting a trip command when the rectified current is greater than or equal to a predetermined threshold for a predetermined duration. The device thus makes it possible to protect a DC-voltage electrical installation in a noisy environment.
