Abstract:

The JSF Autonomic Logistics (AL) system is a new supportability concept that will enable the aircraft to be better utilized throughout the life of the platform, and at a lower cost as compared with legacy aircraft. Autonomic Logistics is, simply put, the automation of the logistics environment such that little human intervention is needed to engage the logistics cycle. Actions that will be automated within the JSF supportability concept include maintenance scheduling, flight scheduling, ordering spare parts, and the like. The cornerstone of Autonomic Logistics is an advanced diagnostic and Prognostics and Health Management (PHM) system. The PHM provides the data, information, and knowledge for initiating the AutoLog chain of events. PHM is the ability of the aircraft to do fault detection (FD), fault isolation (FI), and accommodation real-time on-board the aircraft. Along with this FD/FI capability, some of the other facets of PHM include fault prediction on selected components. parts life usage tracking, fault filtering and reporting, and recommended action to the pilot only when action is necessary. It is intended that in most cases, maintenance actions and lifing decisions will be based on the actual material condition of the equipment components. The proposed architecture of this PHM concept includes a hierarchical approach where data begins at the sensor level and is transported up to area reasoners that turns this data into information about a particular subsystem. From the area reasoner, the information is then passed up to a top level Air Vehicle Reasoner where subsystem information is then fused to give knowledge about the health of the entire air vehicle. Additionally, many of the technologies that are being developed for the JSF PHM suite could be applied to legacy aircraft and would show significant benefits in respect to LCC and maintainability issues. In many cases, the capability of PHM sensors and prognostic technologies will enable the ability to "s...
