摘要
The invention relates to a system for dissipating a lightning current produced by a thunderstorm discharge on an avionic equipment (2) installed on the external skin (20) of an aircraft, said external skin being made of a composite material (21) covered with a layer of expanded metal (22) and comprising an orifice (6) in which there is positioned an aerodynamic plate (7) covering the avionic equipment (2), said aerodynamic plate being attached to the external skin by means of a doubler (3), the system comprising at least one metal plate (23, 30, 34) at least partially surrounding the aerodynamic plate and mounted in such a way as to ensure electrical continuity between the doubler (3) and the layer of expanded metal (22) so as to dissipate the lightning current into the layer of expanded metal.
