[Interaction d'un éclair et d'un avion en vol]
En moyenne, chaque avion de ligne est foudroyé une fois par an. Le foudroiement d'un appareil n'est donc pas exceptionnel et constitue une menace non négligeable pour la sécurité des vols. La compréhension du processus de foudroiement a considérablement progressé ces dernières années, grâce à l'analyse exhaustive des données enregistrées à bord d'avions instrumentés volant dans des zones orageuses. Dans cet article, nous nous appuyons sur la description phénoménologique du foudroiement d'un appareil pour approfondir les bases physiques des différentes phases de l'éclair sur avion.
Roughly speaking, every commercial airliner is struck by lightning once per year. Thus, the lightning strike to aircraft is not uncommon and it poses an appreciable threat to flight safety. The understanding of the lightning strike to aircraft has been greatly enhanced during the last years thanks to a comprehensive analysis of data collected from instrumented aircraft that have been flown into thunderstorm regions. In this article, we will start with the phenomenology of the lightning strike to aircraft and continue with going deeper into the underlying physics of selected processes during the strike.
