为了在静态环境下模拟某新型随行装药的内弹道燃烧性能,采用将小粒发射药进行钢筒中压制成型,端面封堵延时处理的方法得到了一种新型随行装药试样。并将制得的随行药与单樟6/7混合进行密闭爆发器实验,测试了其燃烧性能。实验结果表明:与单樟6/7单独装药相比,其燃烧过程分为2个阶段,且第二阶段燃烧速率远大于第一阶段,通过延迟装置质量和装药密度的调节可以实现对随行药点火延迟时间的控制。随行药具有很高的燃速和较强的燃烧渐增性,在内弹道过程中可有效改善膛内压力分布。
In order to simulate the internal ballistic combustion performance of a new type of random charge under static conditions, a new type of random loading sample was obtained by the method of pressing the small propellant into the steel cylinder and delaying the end face. The obtained random drug was mixed with single camphor 6/7 to conduct a closed-cell burst experiment, and its combustion performance was tested. The experimental results show that the combustion process is divided into two stages and the second stage combustion rate is far greater than the first stage, compared with the single Zhang 6/7 single charge. By adjusting the delay unit quality and charge density, Accompanied drug ignition delay control. Accompanied drug has a high burning rate and strong combustion increasing in the process of internal ballistics can effectively improve the pressure distribution inside the bore.
