Title:
GROUND-DISCHARGE PROTECTIVE METHOD OF AIRCRAFT STRUCTURE
Document Type and Number:
Japanese Patent JPS62168799
Kind Code:
A
Abstract:
The conductivity of the outer surface of skin (2) is enhanced by providing an outer layer of conductive material. The outer surfaces of each external metal fastener (8) and the skin around it are covered with a patch (6) of a strongly dielectric material. Patch (6) is dimensioned to cause current flow from lightning strikes to diffuse to a current density belowan arcing threshold before reaching fastener (8). Preferably, further protection against arcing between the outer surface of skin (2) and metallic fasteners and fittings is provided by coating with a dielectric any surface portions of such fasteners and fittings that contact the skin (2) or an integral continuation thereof. When load requirements permit, fasteners made from dielectric materials are used instead of dielectric coated fasteners.
