SYSTEM FOR DISSIPATING A LIGHTNING CURRENT GENERATED BY A THUNDERSTORM DISCHARGE ON AN AIRCRAFT

摘要

the invention relates to a drainage system, for a current of lightning produced by a lightning discharge on an avionics (2) installed on an outer skin of an aircraft (20), the outer skin being made of a composite material.(21) covered with a layer of expanded metal (22) with a hole (6) in which is placed a plate (7) covering aerodynamics, avionics, the plate (2) is fixed on the outer aerodynamic skin by means of a double (3), the system comprising at least a no metallic plate (23, 30.(34) surrounding at least partially the aerodynamic plate mounted so as to provide electrical continuity between the double layer (3), and the expanded metal (22) in order to ensure a common sight in the drainage layer of expanded metal.
