Coupling of Lightning Stroke Current to Aircraft Balanced Twisted Shielded Pair Cables,
Abstract
The F-18 is the first military aircraft which makes extensive use of graphite epoxy composite materials. These materials are used on the wings, tail, horizontal stabilizer, and on various access doors and panels. In view of these facts, electromagnetic hazards assume a more important role in aircraft survivability, both to man-made and natural threats. In particular, the use of graphite epoxy composites implies a shielding effectiveness which is less than that obtained on metallic aircraft, because of the composite's smaller electrical conductivity and the problem associated with obtaining good electrical joints. The scope of this investigation is not to investigate the susceptibility of the aircraft to all electromagnetic threats. Instead, one of the threats of greatest concern, an attached lightning stroke, is the subject of the investigation.
