Modern aircraft depend on extensive electrical wiring networks for power distribution, avionics, and control systems; however, these wiring systems are vulnerable to wear, insulation degradation, and arcing over time, leading to safety risks and costly unscheduled maintenance. The proposed Electric Health-Monitoring Wiring (E-Wiring) system integrates temperature, current, insulation, vibration, and environmental sensors directly into aircraft wiring harnesses to enable continuous monitoring and intelligent fault detection. Data from these embedded sensors are processed through a distributed edge AI network, forming an Electrical Health Monitoring System (EHMS) capable of real-time diagnostics, predictive maintenance, and fault localization. The architecture comprises smart cable segments with sensor nodes, local harness gateways for edge processing, aircraft-level EHMS integration via AFDX/Ethernet, and cockpit or maintenance displays linked to ground-based cloud analytics for fleet-wide insights. We have an existing method to detect by using acoustic sensing method which can detect ongoing insulation chafing or cut, they are limited in identifying pre-existing damages and by adding multiple acoustics in the existing wire harnesses it’ll add extra load to the aircraft. To overcome this, the system incorporates Time Domain Reflectometry (TDR) technology to detect both existing and potential wiring faults. The TDR circuitry interfaces with onboard devices, injecting test signals into wiring to pinpoint insulation anomalies or conductor breaks without adding significant weight or complexity. The proposed E-Wiring and EHMS solution enhances aircraft safety, reduces maintenance costs, and improves operational availability, offering a scalable approach for both retrofit and new-generation aircraft.
