Embodiment Construction

[0031] The invention is described within the context of a pipeline route for transporting kerosene in the pressurized part of an aircraft.

[0032] figure 1 Section 1 of such a kerosene supply line for an aircraft is represented.

[0033] It refers to a tubular pipe section produced from a pipe having any cross-section—cylindrical or otherwise.

[0034] This pipe section is equipped at its ends with connection members A which allow fixing the pipe to the structural element of the aircraft along which it runs.

[0035] figure 2 A more detailed example is given showing a pipe section 2a, 2b and two pipe section ends 1a, 1b and 3a, 3b.

[0036] Due to safety standards, the pipeline route for hydrocarbon fuels consists of double pipes 1a, 1b, 2a, 2b, 3a, 3b, that is, the pipes 1b, 2b, 3b transporting kerosene are protected by the second pipe 1a, 2a, 3a, so Said second pipe allows recovery of possible leaks and containment of external aggressions, especially fire.

Abstract

The invention relates to a device for protecting piping from lightning, characterized in that the piping consists of tubular metal sections (1, 2, 3) connected to each other by connection parts (6a, 6b, 4a, 4b, 51, 52), a first portion (4a, 4b, 51) of the connection parts being plastic material parts and a second portion (6a, 6b, 52) of the connection parts being metal parts.

Description

technical field [0001] The invention relates to a lightning protection device for pipelines, more precisely, relates to a protection device for pipelines used for transporting hydrocarbon fuels in aircraft. Background technique [0002] The invention applies more particularly in the case of aircraft whose original structure and fuselage consist of non-conductive or weakly conductive composite materials. [0003] In the case of aircraft with a fuselage of composite material, the electrical conductivity of the metal pipes is greater than that of the fuselage, and there is a risk of lightning currents traveling in the metal pipes constituting the hydrocarbon fuel pipelines. [0004] Therefore, it is necessary to make the electrical conductivity of the piping lower than that of the fuselage. [0005] Instead, electrical continuity and grounding of the pipeline needs to be maintained so that the pipeline does not become charged with static electricity. [0006] The technical so...
