The Pacific Northwest National Laboratory (PNNL) has conducted R&D for the US Army on prognostics health monitoring (PHM). The main focus of the work was to demonstrate the feasibility of developing an onboard PHM system for the gas turbine engine used on the M1 Abrams tank. Research was performed on methods for real time, onboard prognostics/engine life expectancy forecasting, and a prototype system was designed, developed, and installed on several test tanks. The purpose of this presentation is to review the approaches to PHM employed in this research, to provide an overview of the PHM prototype and results obtained to date with data collected in the field, and to describe current work aimed at developing a PHM capability for diesel engines.
