Abstract:
An electric cabinet provided with an interconnection system for devices such as computers received in the cabinet. The interconnection system includes at least one waveguide forming part of the frame of the cabinet. The waveguide is provided with openings disposed facing housings for receiving the aforementioned devices. The openings being dimensioned to form a barrier to the passage of radio-frequency wireless communication waves to be transmitted through the waveguide and to form a barrier to external waves.
Abstract:
A pipe for forming air flow pipelines in a structure that includes a flexible tube made from composite material, the tube having, on the length of same, sections for which the wall of the tube is stiffened by means of structural elements made from a rigid composite material incorporated into the wall of the tube. The structural elements are configured and arranged at the surface of the tube in such a way as to form a lattice framework surrounding the wall of the tube. The pipe further includes electrical conductors, disposed longitudinally on the wall of the pipe, the electrical conductors having a straight path at the stiffened sections of the pipe and a meandering path at certain of the non-stiffened sections of the pipe, the meandering allowing the conductor to tolerate the possible twisting of the pipe when it is installed in the structure.
Abstract:
A method for projecting information issued from a digital design model. Calibration is performed by acquiring characteristic data originating from a surface of interest and comparing the characteristic data with virtual data issued from the digital design model. A spatial position of a projecting device is determined. The projecting device comprises a video projector and at least two separate image-capturing devices. Depending on the spatial position, information issued from the digital design model is projected by the video projector onto the surface of interest.

The aircraft (10) includes: at least one electric motor (135); at least one stand-alone electrical power supply (110, 120) supplying power to the electric motor; propulsion elements (130) referred to as “auxiliary propulsion elements”, included in the group including: a stand-alone electrical power supply (130) supplying power to the electric motor, a power supply converting thermal energy into electrical energy and supplying power to the electric motor, and an internal combustion engine; and a structure (100) configured to integrate each electric motor, each stand-alone electrical power supply and the auxiliary propulsion elements, the parameters of the structure being substantially identical regardless of the auxiliary propulsion elements. A method of fitting out such an aircraft is also described.
Abstract:
A multilayer sealed skin, in particular for an inflatable structure and that includes a first polymer film, a reinforcing fabric disposed on the first polymer film and a second polymer film disposed on the reinforcing fabric and adhered by means of an adhesive to the first polymer film through cavities in the reinforcing fabric. The skin can be applied to the production of an inflatable structural element such as an inflatable beam for which the skin forms an outer wall of the structural element and for which the first film of the skin forms an inner face of the outer wall of the structural element, and the second film forms an outer face of the wall.
Abstract:
An ultrasonic device to characterize the flow of resin entering and exiting an injection mold during the phase of impregnation, by the resin, of a preform contained in the mold. The device includes two ultrasonic sensors arranged respectively in the vicinity of the inlet port where the resin enters the mold and in the vicinity of the outlet port where the resin exits the mold. Each sensor emits an ultrasonic wave towards the end of the mold in the vicinity of which it is positioned, and receives the ultrasonic wave reflected by the medium. Preferably, the device determines the stabilization of the flow of resin passing through the mold based on the signals received by the sensors. A method for implementing the device to determine the completeness of the operation of impregnating, with resin, a preform positioned in an injection mold into which the resin is introduced.

Abstract:
A device to correct geometrical differences of surfaces of parts to be assembled at the interface of the assembly. A measurer to acquire data by measuring the geometry of the assembly surfaces of two parts to be assembled to each other with their respective assembly surfaces facing. A simulator configured to simulate the assembly of the parts and to determine from the acquired data at each measured point of a sampling of the interface a thickness of the void resulting from the geometrical discrepancies between the assembly surfaces. An additive fabricator to receive from the simulator data representative of the thicknesses of the voids resulting from the geometrical discrepancies between the assembly surfaces. The additive fabricator configured to deposit material on the assembly surface of at least one of the parts to at least partly fill the void resulting from the geometrical discrepancies between the assembly surfaces.
Abstract:
A process and installation for producing a composite material part in which plies of continuous and electrically conductive fibres are deposited to form a stack of piles on a substrate. At least the face of the substrate bearing the stack is electrically insulating and the following steps are carried out a) an electrical terminal is inserted between the ends of at least two plies placed directly one on top of the other in the stack, and on at least two opposite sides of these plies b) when the fibres are dry, introducing a resin in order to impregnate the fibres and c) making a current flow between the electrical terminals through the plies in order to set the resin by resistive heating.
Abstract:
A method for optimizing the architecture of the power supply of a load, includes the following steps: determination of a mission profile (16) sizing according to the power required by the load over time; definition of the sources of energy storage for hybridization; association of a characteristic behavior model with each source of energy storage; determination of the couples of sources of energy storage that can generate the mission profile with a minimum mass; and determination, from the potential couples of sources of energy storage, of the couple with the weakest mass.
