The lightning swept stroke along an aircraft in flight. Part II: numericalsimulations of the complete process

During a lightning strike to an aircraft in flight, the lightning channel g ets deformed in the airflow and displaced along the aircraft, a so-called s wept stroke. The deformation and the displacement are caused by the interac tion between the aerodynamic dow and the plasma properties of the channel t ogether with the properties of the surface. We give a theoretical analysis and a numerical modelling of the swept-stroke processes. Some numerical sim ulations of the swept stroke are presented and the results are compared wit h existing experimental data with satisfying agreement.
