A two-dimensional version of the super charring materials ablation code is developed for the purpose of studying thermal response of ablative test piece that is put into the arc-heated airflow. The calculated pyrolysis gas pressure and temperature profiles within the ablative test piece are compared with those obtained by one-dimensional calculation, and also with experimental data. The effect of ply angle on pyrolysis gas pressure inside of ablative test piece is examined. 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.
