AIRFRAME DIGITAL TWIN (ADT) Delivery Order FA8650-17-F-2219: Scalable, Accurate, Flexible, Efficient, Robust, Prognostic and Probabilistic Individual Aircraft Tracking (SAFER-P2IAT) Full-Scale Demonstration Experiment
Abstract
Improving the accuracy of structural diagnosis and prognosis to make better maintenance decisions is accomplished through more realistic structural analysis of fatigue crack growth, including sources of uncertainty into predictions, and fusing usage and inspection data to update and reduce uncertainty. A set of methods for uncertainty quantification and updating form the basis of the framework. Modularity supports transition to other platforms and reliability problems. Uncertainty in inputs and outputs is described by parametric or non-parametric probability distributions. Criteria for performing inspections can be established based on probabilities of events.
