Lightning Currents on Fastening Assemblies of an Aircraft Fuel Tank, Part II: FDTD Modeling Merged With a Circuit Model Supplemented by a Statistical Model

This paper presents a fastening assemblies FDTD model based on a lumped element circuit integrated into thin wire formalism. It can be used to quantify current dispersion or extreme current in aircraft fuel tank fasteners and to optimize the lightning protection in hotspot zones. An original method allows the characterization of the fastener lumped resistances. This method dealing with dc measurement and an optimization process is validated...
