 note = {The pyrolysis gas pressure inside ablative material is investigated experimentally and numerically. First, the gas permeability of the ablative material developed in ISAS is measured in order to improve the SCMA code so that it can give the detailed thermal response of ablator. Next, the measurements of pyrolysis gas pressure inside ablator test piece are attempted in the arc-heated wind tunnel installed in ISAS. It is suggested from the experimental data and the computed result that delamination of ablator likely occurs at the region where ablator is not fully charred but partially pyrolyzed, which results in a smaller porosity and higher pyrolysis gas pressure in the region. Finally, a two-dimensional version of the SCMA code is developed for the purpose of studying thermal response of ablative test piece that is put into the arc-heated airflow. It is found that the maximum pressure value along the centerline of the ablative test piece becomes 1/3 of that obtained by the one-dimensional calculation. It is also indicated in this study that the maximum pressure value can be further reduced if carbon-cloths are properly tilted with respect to the ablating surface., 資料番号: AA0048089014},
