- Title
Mechanical and Propulsion Systems Prognostics: U.S. Navy Strategy and Demonstration.

- Abstract
Under the auspices of the Defense Advanced Research Projects Agency Prognosis Seedling Effort, a U.S. Navy strategy has been generated to develop, integrate, and demonstrate diagnostics, prognostics, health monitoring, and life management for propulsion and mechanical systems. This article presents the evolution of this overall strategy and its current status. The SH-60 program was initiated as the first proof-of-concept effort to develop, demonstrate, and integrate available and advanced mechanical diagnostic technologies for propulsion and power-drive system monitoring. Included in these technologies were various rule- and model-based analysis techniques to demonstrate and validate diagnostic and trending capabilities. Recently, there has been increased emphasis on prognostic capabilities, which provide early detection of the precursor and/or incipient fault condition to a component or sub-element failure condition, and can manage and predict the progression of this fault condition to component failure. This approach increases safety and significantly reduces supportability costs over the aircraft life cycle.
