Abstract
Technology for extending the life of fielded systems offers the potential for significant savings in total ownership costs. On-board monitoring combined with physics-based analysis will instill increased confidence in prediction of remaining useful life. The prime contractor OEM is currently working on methodology for JSF 1st stage fan blade prognosis using deterministic methods. However deterministic methods do not consider variability that exists in the real world. The herein technology will develop a probabilistic prognosis approach that considers variability in material properties, loading conditions and mission duty cycle. The focus of this effort will be on HCF foreign object impact assessment. This project will develop a prognosis approach and demonstrate the approach in coordination with OEM JSF health management demonstration testing.
