Leaktight support device for a conduit, method for leaktight installation of a conduit through a bulkhead and use of such a device for leaktight lead-through in a bulkhead of an aircraft tank

摘要

The device (10) has a body (12) provided with a sealed axial passage (14) for a duct and with a sealed peripheral assembling zone in an orifice in a partition of a jet fuel tank. The body has a set of rigid maintaining sectors (20-a-20-d) made of composite material, where each sector comprises a bearing pad (26) for the duct. A sealed material made of silicone is placed between the sectors for forming a sealed passage and around the sectors in the zone, where the body is mounted on the partition. An independent claim is also included for a method for sealed assembling of a duct across a partition using a sealed maintaining device.
