填充物对单孔双基推进剂爆轰性能的影响

Effect of Variable Fillers on Detonation Performance of Cannular Double-base Propellant

为了提高装药的安全性,以非整体式圆环形双基推进剂为主装药,其间隙分别填充氧化剂混合胶液、空气、沙子、水、木屑、橡胶等,采用电离法和见证板法测定装药的爆轰性能。结果表明,用氧化剂混合胶液与水填充的主装药爆轰速度较大,空气填充的主装药爆轰不完全;得到用氧化剂混合胶液与空气填充时非整体式装药的爆速与装药药段长和空隙尺寸关系的表达式。

To improve the safety of explosive charge, non-whole double-base propellants were served as main explosive charge, and their clearance were respectively filled with oxidant gel solution, air, sand, water, wood and rubber etc. The detonation performance of explosive were measured by ionization method and witness steel-plate. The results showed that the detonation velocity for main explosive charges whose clearances filled with oxidant gel solution and water is bigger, detonation with filled air were incomplete. The expression describing the relation of detonation velocity with segment length and clearance size was obtained for non-whole charge whose clearances filled with oxidant gel solution and air.
