Long Range Ultrasonic Inspection of Aircraft Wiring (UltraHandMan)

老化电线检测是航空航天领域关注的问题之一。飞机电线在不断变化的操作条件下运行，即飞机电线可能在寒冷、炎热或潮湿的环境下运行，并随大气压力的变化而变化。在这种条件下操作可能会造成飞机电线绝缘的摩擦、裂纹、割伤、分层或脆化。飞机电线在极端条件下工作，如果变脆或破裂，可能会导致故障。在这些情况下，飞机线路可能存在潜在的火灾危险。据报道，有400起事故是由飞机线路故障引起的。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导线的检测，其维修成本可降低70%，可提高航空航天系统的使用寿命，被认为是航空航天工业发展前景广阔的技术。因此，减少对新产品的需求，这将最终为航空工业节省成本。UltraHandMan项目将开发一种新型的便携式线路检测系统，该系统基于扩展的远程超声波检测技术、先进的信号处理软件、创新的传感器阵列以及充满能量的手持脉冲发生器/接收器。线路上的缺陷会将超声波反射回传感器组件，并由脉冲发生器/接收器检测到。绝缘损伤将通过先进的信号处理和模式识别技术来识别。

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.
