Deep Learning for local damage identification in large space structures via sensor-measured time responses
Due to the stringent requirements imposed by state-of-the-art technologies, most of modern spacecrafts are now equipped with very large substructures such as antennas, deployable booms and solar arrays. However, while the size of these elements increases, their mass is limited by the rocket maximum take-off weight and, therefore, they result to be lightweight and very flexible. A natural concern derived from this trend is that these structures are now more susceptible to possible structural damages during launch phase or operational life (impacts, transient thermal states and fatigue).
