| Abstract Scope |
During atmospheric entry, spacecraft experience extreme conditions, and it is important to better understand how materials in current use by NASA behave under these conditions, to work towards developing new materials. We performed high speed, high resolution, high temperature 3D imaging--using synchrotron propagation-based phase contrast microCT--of spacecraft heat shield and parachute materials under conditions meant to simulate re-entry. The data was reconstructed and analyzed using machine learning approaches on high performance computing systems, and simulations of each experimental run were performed to check the ability of the models to capture all of the relevant features observed in the experiments. In this presentation, both the experimental and computational methods for this work will be described, and both visual and quantitative comparisons of experiment and simulation will be shown. |
