| Résumé : |
This technical article describes the analysis implementation of a structurally-integrated thermal protection system (SITPS) concept in the HyperSizer structural sizing software. The software development is focused on integrating structural and thermal analysis methods for vehicle-level design of Highly Reliable Reusable Launch Systems (HRRLS) under the NASA Fundamental Aeronautics program. The unique feature of the SITPS concept is the AETB ceramic core which acts as an insulator between the hot outer surface and the cooler inner surface of the panel. The structural analysis is accomplished using panel homogenization. This results in an effective constitutive equation for the SITPS panel that is suitable for use in a full vehicle-scale finite element analysis. The thermal analysis of the SITPS concept is accomplished using an existing 1-D thermal analysis model that discretizes the structure and insulation into a series of thermal resistors and masses. Vehicle levet sizing studies are included to compare the performance of SITPS to Gr/Ep and Al 2219 honeycomb sandwich concepts with traditional TPS shielding. These studies are used to establish accurate weight statements for a hypersonic SITPS vehicle concept. FEA verification is included in order to assess the accuracy of HyperSizer's eigenvalue predictions. Finally, the 1-D thermal analysis is validated by comparison of the results to published experimental data |
