Detection, location, characterisation and tracking of faults in Aircraft Wiring

现代飞机包含大量的电缆连接整个机身的飞行关键部件和系统。目前的维修技术和技术不允许飞行操作员和维修人员准确地定位和分类故障，以决定纠正或监控策略。拆除面板的时间用于查找和评估记录的故障、追踪间歇性故障或查找可能因损坏而导致性能降低但未显示为硬/永久性故障的故障。该项目的目的是双重的;首先作为一个故障检测系统，以确定在哪里的布线故障locatedand什么类型的故障已经发生。这将使维修小组能够迅速找到机身内部的故障并进行维修。其次，该系统旨在允许飞机运营商监控紧急或现有故障，以决定最合适的干预时间，例如在下一个计划的飞机维护周期-关键是从反应性转向预防性维护飞机电线互连系统（EWIS）。

Modern aircraft contain significant amounts of cabling linking flight critcal components &systems all over the airframe. Current maintenance technology & techniques do not allowflight operators & maintainers to accurately locate & classify faults to decide on a rectificationor a monitoring strategy. Time is spent removing panels to look for and assess logged faults,chasing intermittent faults or searching for faults that may be causing reduced performancedue to damage but are not showing up as hard/permanent faults. The aim of this project istwofold; firstly to act as a fault detection system to determine where a wiring fault is locatedand what type of failure has occurred. This will enable a repair team to quickly find the faultwithin the airframe and undertake a repair. Secondly the system is intended to allow theaircraft operator to monitor ermergent or existing faults to decide the most appropriate timefor intervention, for example at the next scheduled aircraft maintenance period – critciallymoving from reactive to preventative maintenance of the aircraft Electrical WiringInterconnect System (EWIS).
