Abstract

Lightning is of remarkable importance both for the technical management of an aircraft and for flight safety. A research project is ongoing to predict by simulation the electromagnetic environment inside a metallic-composite aircraft struck by lightning. The analysis involves the computation of the transient electromagnetic field and of the currents and voltages induced within the cable network of the aircraft. This paper deals with the simulation of the complete aircraft by means of a threedimensional (3D) model, the evaluation of the electromagnetic field, the simulation of the cable network connecting the safety critical apparatus and the calculation of the induced transient voltages and currents. The electromagnetic environment is carried out by applying a 3D finite-difference time-domain (FDTD) procedure, while the network is analysed by applying transmission line approach, combined with nodal analysis technique in the frequency domain and then followed by a discrete inverse Fourier transform. © 2001 by the authors.
