Indirect Effects of Lightning on Aircraft and Rotorcraft

J.-P. Parmantier, F. Issac & V. Gobin
This article discusses issues related to indirect lightning on aircraft/rotorcraft. The standard waveforms used for qualifying the vulnerability of a system are introduced, with their frequency spectrum. The identification of the elementary EM coupling phenomenon allows the understanding of the key drivers of the current distribution and field scattering on a complex structure. The system level EM coupling analysis starts with examples of cable-measurements on real aircraft/rotorcraft, from which simple models are derived in order...
