| Abstract: | Utilizing the existing ablation experimental system for the insulator material under oxygen-rich conditions,some ablation boundary parameters were extracted for afterburner insulator material of typical solid ramjet,and operation parameter's range in the experiment system was improved.Three formula of silicone rubber insulator ablation materials were selected and investigated,and the maximal charring ablation rate was obtained respectively.The results show that the charring ablation rate of three kinds of i... |
