Apparatus for preventing lightning strike damage to a structural component

摘要

Preventing damage to a metal component or reducing manufacturing assembly steps. An initial channel, defined by an inner surface, is formed through the metal component. A bushing is placed into the initial channel, the bushing having an outer surface and an inner channel. An interference fit is created between the outer surface and the inner surface. A final channel is formed through the bushing. In forming the final channel, material is removed from the bushing to increase a size of the inner channel to be suitable to receive a fastener and such that the inner surface of the metal component remains unexposed within the final channel. The final channel extends through a second component. A fastener is placed into the final channel to attach the metal component to a second component, wherein electrical magnetic effects occur between the fastener and the bushing.

主权项

1. An apparatus comprising:
a first section comprising a first material; a first bushing disposed through the first section, creating a first channel in the first section; a second section in contact with the first section, the second section comprising a carbon fiber reinforced polymer, the second section including a second channel in communication with the first channel; a third section comprising a second material; a second bushing disposed through the third section, creating a third channel in the third section, wherein the third channel is in communication with the second channel; and a fastener disposed through the first channel, the second channel, and the third channel, wherein the fastener, the first bushing, and the second bushing are configured such that electromagnetic effects occur between the fastener and at least one of the first bushing and the second bushing instead of between the fastener and at least one of the first section and the third section.
