Heating Behaviors of Carbon-besed and Silicon-based Materials in High-temperature Plasmajets

Abstract

When a sample return capsule enters into the Earth's atmosphere, a strong shock wave is generated in front of the capsule, and it is subjected to severe aerodynamic heating. One of the thermal protection methods used to protect the capsule from the heating is the ablation method. In the future, the capsule is expected to become larger and the re-entry speed will increase. In this case, the capsule will be exposed to more severe aerodynamic heating. In order to investigate the fundamental heating behaviors of carbon-based and silicon-based materials, the authors have systematically conducted the heating experiments of these materials in high-temperature plasmajets.
