A Model for Direct-Strike Lightning Excitation of a Conducting Body
A methpd is presented for simulating the electromagnetic excitation of a conducting body when it lies in the path of a lightning strike. A frequency domain analysis is used where an electric field integral equation is solved by the method of moments. The unknown surface current on the body is partitioned into two types, one for the junctions defining the lightning attachment points and one for the rest of the body. Pictures of the body surface current induced on a triangular patch model of an F-14 aircraft are presented for a nose-to-tail and nose-to-wingtlp attachment. Some time domain results are obtained using the simple double exponential model of a return stroke current waveform and numerical inversion of the frequency domain results obtained by matrix inversion.
