| Outline of Final Research Achievements |
In this study, we propose the concept of a nonablative lightweight thermal protection system (NALT) for a Mars exploration mission currently under investigation in Japan. The NALT consists of a carbon/carbon (C/C) composite skin, insulator tiles, and a honeycomb sandwich panel. We obtained the basic thermal characteristics of the NALT by conducting heating tests in high-enthalpy facilities. We measured the thermal conductivity values of the insulator tiles as well as the emissivity values of the C/C skin to develop a numerical analysis code for predicting NALT’s thermal performance in flight environments. Finally, we developed a breadboard model of a 600-mm diameter NALT aeroshell and qualified this model through vibration and thermal vacuum tests.
