A numerical tool to estimate lightning indirect effects on a composite aircraft

Nowadays, with the increasing use of composite materials, lightning indirect effects on aircraft are an important problem of interest. Currents and voltages induced by the lightning strike can perturb the equipment working. The purpose of this study is to develop a numerical tool allowing the estimation of current coupling on wires involved by the lightning strike. The model permits to consider several thousands of wires and is a powerful and useful tool, assisting the aircraft manufacturer in the certification process.
