Generative adversarial networks with Monte Carlo dropout uncertainty quantification for structural health monitoring: Fibre Bragg grating data augmentation comparison in Hawk T1A aircraft

Read the original on arXiv Machine Learning →

The paper presents a data‑augmentation framework that uses conditional generative adversarial networks and Monte Carlo dropout to synthesize structural response signals with quantified uncertainty. The synthetic signals are rigorously compared to experimental data from a BAE Systems Hawk T1A aircraft, showing accurate capture of dominant dynamics and realistic statistical properties. The study evaluates whether the augmented data can improve supervised damage classification and demonstrates the framework’s potential as a digital twin for safety‑critical aerospace structural health monitoring.

A Multi-Fidelity Convolutional Autoencoder-Transfer Learning Framework for Guided-Wave-Based Damage Diagnosis Using Large Simulated and Limited Experimental Datasets

Guided wave-based structural health monitoring (GWSHM) with onboard transducers offers significant potential for the early diagnosis of damage in engineering structures. However, the practical deployment of deep learning models is often hindered by the limited availability of labelled experimental data and the high computational cost of generating large-scale high-fidelity simulation datasets.

Towards Interpretable Damage Detection based on Aerodynamic Pressure Measurements

The paper presents a method for detecting and classifying damage in wind turbine blades using aerodynamic pressure measurements from the Aerosense system. A convolutional neural network was trained on data from a NACA 633418 airfoil mounted on a vibrating cantilever, where damage was introduced via saw cuts. The study also incorporates physics-based insights and explainable ML techniques to interpret how damage affects dynamic response and pressure fields, enhancing transparency and robustness of the monitoring pipeline.
