Abstract: |
To explore new light-weight integrated thermal protection system panel configuration and gain good insight into the responses mechanism, heat transfer and structural field analysis for one single-layer and four double-layer corrugated core panels were performed. The obtained the temperature, buckling, stress and deflection responses were compared, and the deflection and stress distributions as well as thermal buckling mode at the time were discussed for the considered configurations when the temperature difference between the top and bottom face sheet was maximum. The results demonstrated that the non-orthogonal and hat-stiffened double-layer structures provide superior performance to resist thermal buckling deformation in comparison with other configurations. The useful information is provided for the forthcoming optimization in which thermal buckling is considered as critical design driver. |
