Etude expérimentale et théorique d'un arc de foudre et son interaction avec un matériau aéronautique

Aujourd’hui, l’étude des effets directs de la foudre sur les structures aéronautiques pourrait s’appuyer, au moins en partie, sur des outils de simulation. Néanmoins, le manque de données expérimentales sur la phase d’arc impulsionnelle

Nowadays, the study of the direct effects of lightning on aeronautical structures could be based, at least in part, on simulation tools. Nevertheless, the lack of experimental data on the transient phase of the lightning arc does not allow us to just
