AbstractREAD (Reentry Environment Advanced Diagnostics) flight experiment was conducted by making use of the reentry phase of the USERS (Unmanned Space Experiment Recovery System) mission. In this experiment, the recovery module with 0.55 m nose radius was reentered with the velocity of 7.5 km/s, and the radiation spectrum along the stagnation line was obtained. At the high altitude (about 90 km), ablator originated species such as OH, CH, NH, which were not taken into consideration in the pre-flight prediction of the spectrum, were observed mainly. In this study, the effect of the ablator originated species on the spectrum were investigated by CFD analysis. In such high altitude, it is suggested that the role of the ablator originated species can not be negligible in contrast to the preflight prediction.
