- Description
- Notice of Contract Action including Notice of Bidder's Conference and Lab Tour The Airframe Digital Twin (ADT) Spiral 1 program seeks to make the Aircraft Structural Integrity program (ASIP) more proactive by increasing the accuracy of the structural prognoses developed within the Individual Aircraft Tracking (IAT) program for each Mission Design Series (MDS). More accurate prognoses can only be developed with higher fidelity flight loads data, more realistic structural analysis models than currently used and a concerted effort to quantify and reduce modeling uncertainty over time. The ADT Spiral 1 program seeks to augment IAT programs through the fusion of (1) usage/environment data from on-board sensors, (2) maintenance data collected from the field and depot, and (3) data collected as part of the structural development and certification program within high fidelity, physics-based structural prognostic models. The key innovation within this program is the integration of three key technologies into an improved IAT procedure: (1) probabilistic structural reliability analysis (PSRA), (2) on-board and in-situ damage detection, and (3) advanced flight loads simulations. The overall goal of this effort is to develop and demonstrate a Prognostic and Probabilistic Individual Aircraft Tracking (P2IAT) methodology that provides better prognostic capability for fatigue cracking of metallic structures. The P2IAT approach will integrate advanced flight loads simulation, airframe structural stress analysis, fatigue life analysis, probabilistic structural reliability analysis, and uncertainty quantification methods. The methodology will use higher fidelity loads derived from the flight history of the specific aircraft than the current IAT approach to achieve better prognostic results. It will be modular so that the method can be easily applied to different MDS and new analysis models can be readily integrated. Uncertainty in input parameters and output variables for the P2IAT algorithms will be described by probability distributions. Confidence bounds shall be placed on both the input and output probability distributions. Criteria for when to perform structural inspections will be established based on the probability of an event occurring (e.g., a crack of a specified size existing, probability of failure, etc.). The contractor will demonstrate the effectiveness of the P2IAT approach by tracking fatigue damage in two full-scale structural experiments that simulate flight-by-flight loading. These experiments will be conducted by the government, but will be planned jointly with the contractor. Address contractual questions to Lori J. Shirdon, Contract Negotiator, (937) 255-8077, or Douglas E. Covey, Contracting Officer, (937) 656-9626, and technical questions to Douglas A. Henderson, Program Manager, (937) 986-8820, douglas.henderson@wpafb.af.mil.
