摘要

为解决随行装药的点火延迟控制及能量释放稳定性问题，提出了一种新的随行装药方案，采用密闭爆发器与30 mm火炮试验对其延时机构的有效性、能量释放的稳定性及燃速进行了研究。结果表明：依托随行装药高密实性，延时机构可对随行装药点火延迟时间进行有效控制；主装药量一定，延时机构厚度存在较佳值，以获得较优的随行装药效应；试验结果基本稳定，初步验证了随行装药结构可靠，燃烧性能基本稳定，有较好的能量释放规律；随行装药具有较高的燃速、燃气释放速率，多-125发射药含量95%时，其燃速最大值是6/7发射药的46倍，最大动态活度达7.4 MPa-1·s-1.改变随行装药中多-125发射药的含量，其燃速、燃气释放速率可调。

Abstract

In order to solve the problems of the ignition delay control and the energy release stability of traveling charge, a new traveling charge scheme is presented. The validity of time delay unit, stability of energy release and burning rate of traveling charge are studied by the closed bomb and 30 mm gun test. The results show that the ignition delay time of traveling charge can be controlled by the time delay unit based on its high density. There is an appropriate thickness of time delay unit, which can obtain an optimum effect of traveling charge, when the main charge remains constant. The experimental results are basically stable, which preliminarily verified the structural reliability of traveling charge, basic stable combustion performance and favorable energy release rule. The traveling charge has higher burning rate and gas release rate. When the content of porous propellant 125 charge is 95%, the maximum burning rate of traveling charge is 46 times as fast as 6/7 propellant, and the maximum dynamic vivacity reaches 7.4 MPa-1 · s-1.The burning rate and gas release rate of traveling charge can be adjusted by changing the content of porous propellant 125 charge.
