This book details how civil and military aircraft can be shielded from two major threats: electromagnetic interference (EMI) and environmental conditions. Aircraft depend heavily upon electronic systems and interference can come in the form of lighting strikes, radio emitters, nuclear electromagnetic pulses (EMP), or even high power microwaves. The environmental conditions that can damage and corrode aircraft include moisture, rain, and pollution from the atmosphere. Most importantly, this corrosion may damage the conductivity and electromagnetic shielding of the vehicle. This book discusses shielding effectiveness as related to conductivity and demonstrates the relationship of material chemistry to conductivity and corrosion. Coverage fully explains how to optimize shielding effectiveness for aircraft and other vehicles. It also identifies electrically conductive corrosion prevention materials capable of maintaining EMI/EMP protection of aircraft and weapon systems.
