| 摘要: |
| 以ＡＰ／ＲＤＸ／ＨＴＰＢ复合固体推进剂为对象，研究了撕裂速率、添加剂类型、贮存老化等因素对推进剂撕裂性能的影响。实验结果表明，撕裂速率加大使推进剂断裂能升高；不同的添加剂对推进剂的断裂能有不同的影响；键合剂使断裂能升高；推进剂老化一段时间后断裂能降低。 |

| Abstract: |
| he effects of tearing rate, type of additives, aging etc. on tearing charateristics of AP/RDX/HTPB composite propellant are investigated. The experimental results show that increasing tearing rate can increase fracture energies of propellant; bonding agent can increase fracture energies of propellant; aged propellant has lower fracture energies. |
| Key words: Nitramine propellant Hydroxy terminated polybutadiene propellant Tear test |
