| description | ObjectiveLightning electromagnetic effects and coupling characteristics are an important analysis basis for the lightning protection design of the electronic and electrical equipment of helicopters.MethodsRP5416 standards, in the CST cable studio based on TLM, the influence factors and rules of the electromagnetic environment and cable coupling level of carrier-borne aircraft under typical lightning strike mode are studied.ResultsThe results show that the establishment of a lightning electromagnetic field is a rapidly changing process which presents complex changes in terms of time, space and structure. The aircraft lightning coupling mechanism is the interaction between the resistive coupling of the lightning flow redistribution and the resonance coupling of the airframe gap, and is strongly dependent on the frequency. The cable induction level is affected by the aircraft skin resistance, lightning current waveform parameters, cable shield impedance and other factors.ConclusionsThis study reveals the mechanism of lightning electromagnetic coupling and the related influence law of the lightning electromagnetic induction of the cable, providing a basis and support for aircraft cable laying and lightning electromagnetic environment protection. |
