FAULT LOCATING INTEGRATED HYBRID HARNESS TEST SYSTEM (FLIHHTS)

FLIHHTS是英国航空光学公司和MK测试公司之间的合作项目，由空中客车公司提供支持。目标是开发一种自动故障定位系统，用于测试航空航天混合布线和光纤线束。当前飞机线束的故障检测、路径完整性和损耗检测过程既繁琐又复杂。通常需要几件测试设备，并涉及对结果的主观解释，这种情况需要开发一种新的创新测试解决方案。FLIHHTS将开发电气和光学TDR（时域反射计）技术，该技术可以感知线束上问题路径的故障位置，并向操作员提供清晰的信息。它将提供映射到布线模型的功能，从而提供访问信息以允许对故障进行修复。这将节省大量的时间和成本，无需完全更换线束，提高平台的可用性，减少环境浪费并改善记录保存。该系统将增强OEFHTS项目正在开发的能力，该项目正在开发单端路径损耗和完整性测试。该系统将被设计用于制造环境，用于最终组装/测试，也将是现场便携式的，用于现场、平台诊断和售后维护、修理和大修。总的来说，这些光学和电气测试特性将为航空航天市场和其他正在安装混合动力的新兴市场提供无与伦比的、极具吸引力的测试系统。

FLIHHTS is a UK collaborative programme between AVoptics and MK Test and supported by Airbus. The goal is to develop an automated fault locating system for testing aerospace hybrid wiring and fibre optic harnesses. The current process of fault detection, path integrity and loss testing on aircraft harnessing is laborious and involved. Often requiring several pieces of test equipment and involving subjective interpretation of results, the situation needs development of a new innovative test solution. FLIHHTS will develop electrical and optical TDR (time domain reflectometry) technology that can sense the location of faults for problem paths on the harness and present clear information to the operator. It will provide the capability to map to wiring models, thus providing access information to allow repair of the fault. This will provide massive time and cost savings, removing the need for full replacement of a harnesses as well as increasing platform availability, reducing environmental waste and improving record keeping. The system will augment the capabilities being developed on the OEFHTS programme which is developing single-ended path loss and integrity testing. The system will be designed for use in a manufacturing environment, for final assembly/test and will also be field-portable for in-situ, on-platform diagnostics and aftermarket maintenance, repair and overhaul use. Collectively, these optical and electrical test attributes will provide an unrivalled and highly attractive test system for the aerospace market and also other emerging markets where hybrid harnessing is now being installed.
