AB - Charring thermal protection systems have been used to protect hypersonic  vehicles from high heat loads. The pyrolysis of charring materials is a  complicated physical and chemical phenomenon. Based on the pyrolysis  interface model, a simulating approach for charring ablation has been  designed in order to obtain one dimensional transient thermal behavior of  homogeneous charring materials in reentry capsules. As the numerical results  indicate, the pyrolysis rate and the surface temperature under a given heat  flux rise abruptly in the beginning, then reach a plateau, but the  temperature at the bottom rises very slowly to prevent the structural  materials from being heated seriously. Pyrolysis mechanism can play an  important role in thermal protection systems subjected to serious aerodynamic  heat.
