Abstract: The aircraft indirect effect test method was
studied in this paper based on the numerical simulation method. Meanwhile
the influence of the return conductor arrangement on the load matching and
current distribution was also analyzed. The aircraft lightning test system
models with coaxial return path were established, and their distribution
parameters and the characteristic impedances were calculated. The current
resonant under different load impedance was analyzed using one dimensional
FDTD (finite-difference time-domain) algorithm. On this basis, the current
density distributions on the surface of the fuselage with different return
conductor arrangements were calculated by the simulation software CST. The
conclusions provide foundation for the further research on the return
conductor configuration of fixed wing aircraft lightning test.
Keywords: Aircraft, lightning indirect effect test, return conductor, distribution parameters
