Efficient Atl Simulation of Lightning Currents in Cable Harnesses

Aircraft electrical and electronic systems have to be protected against the effects of lightning and to show compliance with federal regulations. Simulation offers an alternative to physical testing that can quickly calculate actual transient levels (ATLs) - the voltage and current amplitudes and waveform generated on the aircraft wiring when an aircraft is exposed to lightning. In this tech talk, we demonstrate an ATL simulation workflow for aircraft that takes into account complex structures such as wiring and composite materials quickly and efficiently.

Highlights: 

• Analyze ATLs on aircraft wiring during lightning strike without the costs of physical testing and prototypes.
• Accurately model the electromagnetic properties of composite materials.
• Simulate large, complex aircraft bodies efficiently with the Transmission Line Matrix (TLM) solver
