Study of numerical simulation of the lightning indirect effects on helicopter

To improve the protection performance of helicopter against lightning, this paper presents a full-wave electromagnetic transient simulation based on the Transmission-line Matrix (TLM) to simulate helicopter struck by high current pulse and study its lightning indirect effects according to the SAE-ARP 5416A. The distributions of the electromagnetic field of the helicopter stroke by the lightning are discussed. The results indicate that this simulation method can effectively analyze the helicopter indirect effects stroke by lightning and guide the lightning protection design of the helicopter without the condition to develop the full-scale helicopter experiment.
