Thermal characteristics of CFRP ablative materials that were developed for a general-purpose are successfully obtained. Thermal properties of the CFRP ablator were measured. The experimental data obtained in the arcjet wind tunnel were analyzed numerically. The thermal response of ablative TPS of the Hayabusa capsule is calculated along the most probable reentry trajectory by using the analysis method. The calculated results are compared with the flight data obtained at the present time. It is found that a reasonable agreement is obtained between the calculated surface temperature and the temperature values estimated from the ground observation. The present analysis method was also applied to the analysis of a lightweight ablator.

成功地获得了开发的通用CFRP烧蚀材料的热特性。测量了CFRP烧蚀材料的热性能。对电弧加热发动机风洞实验数据进行了数值分析。利用该分析方法计算了隼鸟号飞船沿着最可几弹道上烧蚀热防护系统的热响应。计算结果与目前获得的飞行数据进行了比较。结果表明，计算得到的地表温度与地面观测得到的温度值基本吻合。本文的分析方法也被应用到一个轻型烧蚀材料的分析中。
