| Abstract: | The EPDM insulator's ablating processes and some models for the solid ducted rocket motor are introduced simply and the main thermochemistry reactions on the insulator's surface and ablation products are analyzed based on the omitting of particle collision and mechanical impact.Approximating prediction of charring layer ablating was presented and the preliminary exploring of the thermochemical ablation mechanism of EPDM insulator was conducted. |
