| 抄録 | We examined the construction of an analytical model to improve the accuracy of the thermal protection performance evaluation analysis of the ablator. In the conventional arc heating wind tunnel test, the difference in the thickness of the specimen before and after the test was used as the amount of surface recession, but the expansion of the ablator due to carbonization of the resin was included, which caused a difference from the numerical analysis. Therefore, we evaluated the expansion of the ablator due to carbonization of the resin and attempted to introduce it into the evaluation analysis by modeling the thermal expansion characteristics in order to further improve the analysis accuracy. |
