Dynamic Autonomous Test Systems for Prognostic Health Management

摘要

This paper presents the state of the art in real time reactive supervision using micro-module sensors. The paper will show how automatic test equipment is becoming more and more an anachronism as the Joint Strike Fighter Prognostic Health Management (PHM) team forges new links that connect onboard, event based diagnostics and prognostics to ground-based support. The paper will discuss how on-aircraft PHM combines micro electro-mechanical systems (MEMS) and micro-electro-optical systems (MEOS) with prognostic microprocessors to sense, detect, consider, prognose, message and perhaps correct problems. The paper will explain how miniature electronic technology (E.T.) will use web based JAVA technology to receive rules for PHM and send results of PHM via downlink to the Joint Distributed Information System. (JDIS) The paper will show how E.T. is embedded in the wiring, cables and connectors that are the life lines of the electronic systems, and how E.T. will be fused into mechanical structures to detect aging and battle damage. Finally, the paper will describe the cost benefits that result from radically changing the current way defense systems are supported.
