ABSTRACT:
An aircraft static discharger and mounting structure therefor is disclosed formed of non-metallic conductive material, such as carbon filled nylon, for mounting an aircraft static discharger onto a graphite and/or boron composite aircraft skin. The discharger includes a mounting structure formed as a sub-base having a lower surface provided with downwardly extending conical projections terminating in points which engage the underlying graphite composite surface and form electrical contact therewith, providing for the mounting of the sub-base to the composite surface by conventional non-conductive epoxy. A surface conductive to lightning currents is provided by bonding powdered aluminum to the outer surfaces of the discharger base and the sub-base which, together form a lightning diverter strip formed on the discharger, transfer lightning currents over the surface of the base and sub-base to the underlying aircraft structure.
