Aerospace Sector: Unmasking the Intricacies of Lightning Strike Protection

Why is Protection from Lightning Strikes Important in Aerospace?

The aerospace industry invests significantly in protective measures against lightning strikes, driven by the need to ensure aircraft safety and prevent system failure. As lightning can lead to catastrophic disruptions, even complete electrical shutdowns, such measures are of paramount importance. Despite their occasional occurrence, lightning strikes to airborne craft can have significant financial and safety implications.

What Remedial Actions are Industry Standards?

In response, the aerospace sector employs a host of strategies, ranging from conductive exterior coating and embedding metal mesh in composites to installing lightning arrestors. Faraday cages, primarily used in aircraft design, act as an external shield, protecting internal systems and passengers. Other necessary installations include surge protection devices for voltage surge mitigation, to preclude damage to sensitive aviation electronics.

What are Future Trends in Lightning Strike Protection?

Despite considerable advances, the quest for near-perfect lightning strike protection in aerospace continues. Future endeavours will likely utilise increased digitalisation, predictive analysis and improved materials. With aviation transitioning towards more electronic and composite materials, challenges related to lightning protection produce research opportunities. Simultaneously, adapting to the dynamic and complex nature of lightning behaviour also roots for further exploration in this niche field.
