Abstract:

为了定量分析AP/HTPB复合底排推进剂初温对弹丸落点散布的影响, 引入了AP/HTPB复合底排推进剂燃速初温敏感因子(σp)。鉴于AP颗粒对底排推进剂燃速起主导作用, 计算分析了Glick、Kubota及BDP三种模型AP颗粒初温敏感因子模型的结果。底排装置内工作压力接近0.1 MPa且变化不大, 故取常值σp=0.43%/K。针对某155 mm底排弹, 通过建立其内弹道及6D外弹道模型并联立求解, 计算了底排推进剂初温对弹丸落点散布的影响, 发现射程对温度的敏感因子约为8.22 m·K-1, 侧偏对温度的敏感因子约为0.447 m·K-1, 射程随初温的变化率与文献值比较接近, 误差为12%
