Problems solved by technology

[0008] In fact, the result of these aerodynamic disturbances is an increased frontal drag caused by the laminar / turbulent transition, whereby the fuel consumption of the aircraft increases very significantly, which is inconsistent with the economic requirements of air transport companies

Embodiment Construction

[0058] figure 2 A wall panel 3 equipped with a lightning protection system according to a first embodiment of the invention is shown. The panel has a sandwich composite structure comprising a core 18 and two walls 22 and 12 on either side of the core on the outer surface of the core.

[0059] These walls 22, 12 constitute the outer skin of the composite panel, usually made of very strong fibers such as glass fibres, quartz fibres, aramide fibers or basalt fibres. The core panel 18 may be made of foam, honeycomb or wire. The skin is joined to the core by the polymerization of the resin.

[0060] Aircraft radomes are often equipped with wall panels of sandwich composite structures which are electrically insulating but permeable to electromagnetic waves. During flight, the upper wall 22 of the wall plate constituting the outer wall of the radome receives the flow of air.

[0061] The wall panels are equipped with a lightning protection system consisting of conductive strips 1...

Abstract

The subject of the invention is an anti-lightning system for a composite structure (3) having an external surface (9) liable to be subjected to an air flow, said system comprising at least one electrically conducting strip (1) and fasteners fastening said strip to the structure, said strip being electrically connected to an electrical earth for removing current. According to the invention, said strip has a shape intended to collaborate with a housing (6) created at said external surface (9) so that the external surface of the strip (21) lies flush with said external surface (9) of the structure, and said fasteners comprise an upper part (2) flush with the external surface (21) of the strip.

Description

technical field [0001] The invention relates to a lightning protection system for protecting a composite structure, in particular a wall panel with a light central core, such as a honeycomb or foam core. The invention is particularly suitable for the protection of radomes or fairings of aircraft consisting of panels of composite structure. More precisely, the invention relates to a lightning protection system comprising conductive strips located on the outer surfaces of these panels for attaching lightning strikes and directing the currents generated by the impact of the lightning strikes on the outer walls of the radome to the aircraft ground flow. Background technique [0002] Composite structures are widely used due to their high mechanical strength with very low mass. These structures are widely used by the aviation industry to furnish the outer walls of aircraft, such as radomes located at the front of the aircraft and fairings of the aircraft. However, when the oute...
