Getting the Right Bonds
Things were so much easier with aluminum aircraft structures. The structure acted as an EMI shield, electrical grounding could be done right to the structure without additional effort, and the electrical mating of the structure was straight forward. Now, with composite structures, aircraft design concepts such as electrical bonding, particularly in the case of handling lightning strikes, becomes more important.
When done right, the impact of a lightning strike should have a limited impact.
In this article, we review the concepts around primary aircraft bonding, its requirements, and the implementation as they relate to lightning strike.Read more
