| Research Abstract |
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.
