High value asset vehicles, or vehicles where safety/operational readiness is important, benefit from an accurate remaining useful life (RUL) estimate. For these assets, RUL allows operators to realize revenue because of improved availability. This paper uses a hybrid, high cycle fracture mechanics model to improve the RUL estimate. The hybrid method’s performance is validated using prognosability, trendability and monotonicity against two existing models using a real-world data set. The improved model allows a longer time period to marshal the resources needed for repair or give operations personnel an extended window to bring other assets to cover missions that would otherwise be unavailable.
