For a re-entry capsule which carries out the atmospheric entry, the ablator is used for the thermal protection material. In order to design the heat protection system of the capsule, it is necessary to understand the thermal behavior by heating tests and numerical simulations. In this study, the ablation analysis program was developed to simulate the heat-resistant characteristics of the ablator. The ultra-light weight CFRP ablator(=LATS) was developed recently and arc-heated tests of the LATS ablator were carried out. Test results (measured data of temperature, mass loss, etc.) are compared with those of ablation analysis. It is confirmed that mathematical model used in the ablation program can express the heat-resistant behavior of the LATS faily well.
