Long Range Ultrasonic Inspection of Aircraft Wiring (UltraHandMan)

老化电气线路检测是航空航天领域关注的问题之一。航空器电线在不断变化的工作条件下运行，即航空器电线可能在寒冷、炎热或潮湿的环境中工作，大气压力变化。在这种条件下操作可能会在飞机电线的绝缘中产生摩擦、裂缝、割伤、分层或脆化。飞机电线工作的极端条件可能会导致故障，如果它变得易碎或破裂。在这些场景中，飞机布线可能存在火灾隐患。据报道，已有400起因飞机布线故障而发生的事件。因此，需要一种检测技术来提高飞机布线的可靠性。无损检测技术可用于飞机钢丝绳的检测，被认为是航天工业降低维修成本70%、提高航空航天系统使用寿命的最有前途的技术。因此，减少对新产品的需求，最终将为航空业节省成本。UltraHandman项目将开发一种新型的便携式布线检测系统，该系统基于扩展的远程超声波测试技术、先进的信号处理软件、创新的传感器阵列以及通电的手持脉冲发生器/接收器。线路上的缺陷会将超声波反射回传感器组件，并由脉冲器/接收器检测到。绝缘损坏将通过先进的信号处理和模式识别技术识别。

Ageing electrical wiring inspection is one of the concern in aerospace sector. Aircraft wires operate under constant change of operational conditions i.e. aircraft wires might operate under a cold, hot or humid environment with variations in the atmospheric pressure. Operating in such conditions might create chafes, cracks, cuts, delamination or embrittlement in the insulation of the aircraft wires. The extreme conditions under which aircraft wires operate may cause failure if it becomes brittle or cracked. In these scenerios aircraft wiring can be potential fire hazard. There have been 400 reported incidents due to aircraft wiring failures. Therefore, there is a need for an inspection technique to improve the reliability of the aircraft wiring. NDT technology can be used to inspect aircraft wires and is regarded as the promising technology for aerospace industry to reduce its maintenance costs by 70% and can increase the system lifetime operation of aerospace systems. Consequently,reducing the need for new products, which will ultimately save cost for aviation industry. UltraHandMan project will develop a novel portable wiring inspection system based on extended long range ultrasonic testing techniques ,advanced signal processing software, innovative sensor array in combination with energised handheld pulser/receiver. Flaws in the wiring will reflect ultrasound back to the sensor assembly and will be detected by the pulser/receiver.Insulation damage will be recognised by advanced signal processing and pattern recognition techniques.
