As part of the technology research engaged in the EU
Clean Sky 1 project, we present in this paper an electrical structure
network (ESN) designed to prevent the impact on an electronic
equipment of unwanted voltage drops appearing when nonmetal
composite materials are used for grounding. An iterative process
has been followed to reach an optimal tradeoff solution meeting all
the aircraft requirements: structural, safety, low weight, electrical,
etc. Guidelines on the design of a low-impedance metal ESN, to
minimize the inductive behavior of the power distribution network,
are outlined in this paper. To this end, we employ the UGRFDTD
simulation tool, combining finite-difference time domain to analyze
the general EM problem, and a multiconductor transmission-line
network to handle internal coupling between cables running along
coinciding routes. The capability of this tool to create time-domain
snapshots of surface currents is shown to provide a useful way to
optimize the ESN, thanks to the insight gained on the physics of
the problem.
