Abstract
Impact Technologies proposes to develop and demonstrate a monitoring system that assesses the health of aircraft hydraulic pumps and motors. The approach described herein includes performance models, feature level fusion, and adaptive modeling forestimating degradation through the collection of in-line pump data and onboard processing. This model-based and feature fusion approach will significantly improve the remaining life predictions over what is possible using single parameter trending. Theappropriate performance and degradation models will be developed within a probabilistic framework that inherently captures distributions in the data due to random processes and measurement error. Moreover, the failure probability framework will directlyidentify confidence bounds associated with specific component failure modes progression. By providing continuous, on-line updates/adjustments of the critical parameters used by the fatigue/damage models based on system level measurements, more accuratefailure rate predictions can be made throughout the life of the component.
