钝感火药膛内燃烧规律的实验研究

Experimental Study on Combustion Rules in Bore of Deterred Propellant Charge

本文以钝感火药在膛内燃烧时的实测ｐ－ｔ曲线为基础，研究了钝感火药装药膛内的ｐ－ｌ曲线、ｖ－ｌ曲线以及两条曲线特征点参数的变化规律，并分析了主装药与钝感火药的混合比例，钝感火药的钝感剂含量对上述曲线的特征点参数的影响，这对钝感火药装药的理论研究和装药结构设计具有重要参考价值。

The p-t,p-l,v-t and v-l curves of deterred propellant charge and the parameters at characteristic point have been studied.The influence of mixing proportion of main propellant and coated propellant and deterring agent content of deterred propellant on those curves and parameters is analyzed.The results are important in the theoretical study of deterred propellant charge and in design of charge structure.
