Abstract: |
The charring ablation characteristics of solid rocket motors forward dome insulation in the acceleration environment were investigated by experiments.The ablation test motor and corresponding centrifugal ignition test device were researched and developed.By simulating actual ablation environment,the ablation tests of NBR and EPDM insulation were performed in different axial acceleration conditions.The influential regularities and empirical formulas were obtained |
