Aerospace series - Fibre optic systems - Handbook - Part 003: Looming and installation practices

Looming and installation practices are a critical aspect of any aircraft electrical/avionics installation. In order to provide a reliable and efficient system it is important that the harness installation is designed for reliability and maintainability. This concept holds true for both copper based and fibre optic harnesses.
The objective of this part of EN 4533 is to provide technical advice and assistance to designers and engineers on the incorporation of fibre optic harnesses into an airframe, while maintaining maximum compliance with current aircraft electrical harness procedures. This part considers the looming and installation aspects during initial design, throughout the manufacture and installation of the fibre optic harness and how the practices chosen affect through life support of the harness.

Luft- und Raumfahrt - Faseroptische Systemtechnik - Handbuch - Teil 003: Verfahren zur Fertigung und Installation von Leitungsbündeln

Fertigungs- und Installationsverfahren für Leitungsbündel sind ein kritischer Aspekt in jeder elektrischen/für die Luft- und Raum¬fahrt vorgesehenen Installation in Luftfahrzeugen. Für die Bereitstellung eines zuverläs¬si¬gen und effizienten Systems ist es wichtig, dass die Kabelbauminstallation für Zuverlässigkeit und Wartungs¬fähigkeit ausgelegt ist. Dieses Konzept gilt sowohl für Kupfer- als auch für LWL-Kabelbäume.
Zweck dieses Teils von EN 4533 ist die Bereitstellung technischer Empfehlungen und Unterstützung für Konstruk¬teure und Ingenieure für den Einbau von LWL-Kabelbäumen in ein Luftfahrzeug und gleichzeitiger Über¬einstimmung mit den derzeitigen verfahren für elektrische Kabelbäume in Luftfahrzeugen. Dieser Teil behandelt die Aspekte der Fertigung und Installation von Leitungsbündeln während der ersten Konstruktions¬phase, der gesamten Herstellung und der Installation von LWL-Kabelbäumen sowie den Einfluss der ausge¬wählten Verfahren auf die auf die Unterstützung des Kabelbaums während dessen gesamter Lebensdauer.

 Part 003: Looming and installation practices  Part 004: Repair, maintenance and inspection b) Background It is widely accepted in the aerospace industry that photonic technology offers a number of significant advantages over conventional electrical hardware. These include massive signal bandwidth capacity, electrical safety, and immunity of passive fibre-optic components to the problems associated with electromagnetic interference (EMI). To date, the latter has been the critical driver for airborne fibre-optic communications systems because of the growing use of non-metallic aerostructures. However, future avionic requirements are driving bandwidth specifications from 10’s of Mbits/s into the multi-Gbits/s regime in some cases, i.e. beyond the limits of electrical interconnect technology. The properties of photonic technology can potentially be exploited to advantage in many avionic applications, such as video/sensor multiplexing, flight control signalling, electronic warfare, and entertainment systems, as well as in sensing many of the physical phenomena on-board aircraft. The basic optical interconnect fabric or `optical harness’ is the key enabler for the successful introduction of optical technology onto commercial and military aircraft. Compared to the mature telecommunications applications, an aircraft fibre-optic system needs to operate in a hostile environment (e.g. temperature extremes, humidity, vibrations, and contamination) and accommodate additional physical restrictions imposed by the airframe (e.g. harness attachments, tight bend radii requirements, and bulkhead connections). Until recently, optical harnessing technology and associated practices were insufficiently developed to be applied without large safety margins. In addition, the international standards did not adequately cover many aspects of the life cycle. The lack of accepted standards thus lead to airframe specific hardware and support. These factors collectively carried a significant cost penalty (procurement and through-life costs), that often made an optical harness less competitive than an electrical equivalent.
c) The fibre-optic harness study The Fibre-Optic Harness Study concentrated on developing techniques, guidelines, and standards associated with the through-life support of current generation fibre-optic harnesses applied in civil and military airframes (fixed and rotary wing). Some aspects of optical system design were also investigated. This programme has been largely successful. Guidelines and standards based primarily on harness study work are beginning to emerge through a number of standards bodies. Because of the aspects covered in the handbook, European prime contractors are in a much better position to utilise and support available fibre optic technology. SIST EN 4533-003:2009
