Test of the lightning indirect effects on an aircraft

With the development of electronics and materials, the requirements of aircraft lightning protection ability increasingly improved. In this paper, a scale model of a helicopter as a test object, the lightning indirect effects test method is described and studied in detail. Two kinds of the circuit conductor arrangements are designed. The electric and magnetic field values of the nose, middle and the tail of the helicopter in each arrangement are measured to obtain the pulse waveforms and the peak value data. Finally, the regularities of the electric and magnetic fields distribution are summarized and the peak data are evaluated.
