This research presents an exciting breakthrough in aviation safety by combining multi-fidelity digital twins with advanced AI to overcome the critical lack of real-world fault data. By integrating a specialized fault injection engine with a Large Language Model (LLM), the framework not only identifies issues with incredible precision but also generates clear, human-readable diagnostic reports. It is a brilliant example of how AI can turn complex data into actionable insights for safer skies.
Key Takeaways
- •A dynamic digital twin was built using a 6-DoF flight dynamics engine to simulate and monitor 19 different engine fault types.
- •Innovative high and low-fidelity data paths allow for both deep analytical deviation signals and real-time online computations.
- •The system leverages a Large Language Model (LLM) to automatically generate clear, interpretable diagnostic reports for human operators.
