Modélisation électromagnétique unifiée pour les contraintes foudre et champ fort sur aéronefs

Abstract : During their missions, helicopters may fly near to high power radar and radio transmitters. These emissions can disturb electronic systems necessary to safety, especially during take-off and landing. Some regulatory requirements need to be considered during the development of new aircraft in order to be able to certify them. Part of the design studies are based on 2D and 3D numerical simulations to define the level of electromagnetic protection needed. Tests on real aircraft are also performed in order to validate these calculations and achieve the certification protocol. The objectives of this thesis are on the first hand to improve the numerical model used to be more predictive for HIRF problems and on the other hand to establish an extrapolation protocol in order to manage the LIE and HIRF problems with the same calculation. This extrapolation protocol reduces three-day calculation times to 7 hours. In the purpose of solving this double problematic, finite difference time domain methodology is used mainly with the ASERIS-FD software. For the extrapolation protocol, the Matrix Pencil method is applied.
