In the domain of aeronautics, the future more electric aircraft will have to face a difficult issue related to the increasing number of wires and connectors, impacting on the weight and system reliability. A possible solution for solving at least part of this problem is to introduce power-line communication for specific applications. In this paper, the cabin lighting and communication system has been...
This paper presents a comprehensive application of the Field-to-TL approach implemented through a computer framework designed to facilitate data exchange among different computational tools. The framework is used also to compare results from different codes, specifically MDD (Multilevel Domain Differentiate) and CRIPTE, thus providing a validation test case for both of them. Furthermore, the comparison...
The work presented in this paper deals with the possibility of implementing a power line communication in aircraft. A tree-shaped architecture of a network has been simulated for determining the distribution of the transfer function between different points on the line. Comparison with results obtained on a real network has been performed. The performances of an OFDM link have been determined by introducing...
The possibility of using power line communication to transmit information in a large aircraft is studied. The communication link, which has been identified and chosen in the frame of the TAUPE European project, is the cabin lighting system since its tree shape and large structure allows covering most of the other possible applications. A statistical theoretical analysis, based on the multiconductor...
This paper describes the procedure put to the fore in the EC's FP7 HIRF-SE project for carrying out HIRF simulations at aircraft level. The solution proposed is based on the use of MTLN models cable links under test and a 3D full wave solver including thin wire models in order to take into account coupling with the whole structure and the rest of the wiring. Further simplifications based on the cable...
This paper deals with the numerical assessment of propagation channel characteristics for future application of power line communications technology in aircrafts. First of all, since exhaustive experimentation on in-board architecture are not possible, it is shown how numerical simulations on a given architecture possibly concerned by PLC implementation can help to the design of a test bench. Finally,...
This article presents the interest of numerical simulation as a helpful complement for the electromagnetic analysis of complex and large systems, particularly at the definition phase of a project. It deals with the optimisation of the lightning protection system of the VEGA launching pad, located in Kourou, French Guyana. After a preliminary step based on the generation of a simplified model of the...
Possible applications of PLC in aircraft are investigated. The scenario which has been selected is a data transmission for the remote control of the lighting system of the cabin. Indeed, the tree-shaped architecture of the cabling is complicated enough to be representative of many other harness aircraft configurations. Narrow band and wide band channel characteristics are deduced from a theoretical...
This paper describes a simplification technique in order to model a complex cable bundle made of a large amount of wires. The basic principle consists in the description of the topology of the cable bundle in terms of point-to-point cable links and to model those cable-links as equivalent wires in a multiconductor transmission line network model. The different steps required to build the model are...
This paper presents some discussions concerning the application of the "Equivalent Cable Bundle Method" on real automotive cable-networks in the high frequency domain. The principle of this modelling method, dedicated for helping system EM immunity assessment, is to reduce the complexity of point-to-point cable-links by grouping together the conductors according to their terminal loads and...
