| 摘要: |
| 为克服某起动器用复合推进剂装药存在燃气残渣多的缺陷,通过物性数据比较及内弹道性能计算,从三个备选双基配方中选出一个与该复合装药性能相近的配方来替代它。对选出的双基配方进行了验证,同时研究了辅助催化剂、辅助增塑剂、燃烧稳定剂对双基推进剂燃烧性能的影响。实验表明:所选的双基推进剂能满足该起动器对装药的要求。 |

| Abstract: |
| To solve the problem that the composite propellant in some starter had the limitation of mass combustion residue, a double-base (DB) formulation was selected from three formulations by comparing the combustion performance and interior ballistic properties with that of the composite charge. The influences of some assistant catalysts, assistant plasticizer and combustion stabilizer on the combustion performance were studied. Experiments conform that the DB propellant can fulfill the demands of the starter. |
