AbstractThe objective of this proposal is to develop a feasible design for intermittent electrical fault detection and location for a weapons system using analog S/SSTDR for continual monitoring. We have already demonstrated the feasibility of the basic S/SSTDR technology for live aircraft in flight where analog real-time, randomly occurring, anomalous or intermittent age-related failure events are commonly not reproducible on the ground. In this project we will address the specific design considerations for full system deployment in both airborne and ground-based systems. This will include location, size, and weight of the sensors, power management (battery, power scavenging, etc.), data acquisition (wireless, infrared, etc.), feedback, and analysis (on board / off board), assessment of the required speed of acquisition and testing, the decision structure for responding to detected events. BENEFITS: POTENTIAL AIR FORCE COMMERCIAL APPLICATIONS The system being designed for this project is a weapon system test and maintenance method that is focused on finding intermittent faults and problems associated with age and incidental damage in an electrical wiring system. In addition to all weapon systems, all aircraft could benefit from similar application of the technology. This technology offers significant improvements in maintenance strategy for any application where there are intermittent electrical failures where the root cause is not easily found. POTENTIAL NON-AIR FORCE COMMERCIAL APPLICATIONS In addition to the Air Force applications, similar opportunities naturally exist in the commercial aerospace industry as well. This project paves the way for future in-flight wiring health management including potential prognostic health management applications. The first generation of in-flight sensors will be used to monitor systems for existing damage as well as to collect data for later prognostic applications. But aircraft are not the only applications needing this technology. Communication systems, overland power distribution, other types of transportation vehicles (trains, buses, large industrial equipment, automobiles, ships, etc.), consumer electronics, housing, large buildings and other structures, large control and monitoring systems, etc. Virtually every aspect of our lives are touched by electrical systems with aging wiring challenges, and this technology can radically change the maintenance paradigm in all of these applications.
