针对未完善的钝感对发射药内弹道性能影响的研究现状,该文利用密闭爆发器试验和靶场射击试验研究了钝感对发射药燃烧规律的影响,建立钝感发射药的燃烧数值模型,提出确定钝感药燃烧特征量的方法,并计算分析钝感发射药的内弹道特性,计算结果符合膛内射击过程的变化规律,与射击试验结果吻合很好
Aiming at the present situation of the research on the influence of imperfect insensitivity on the internal ballistic performance of launching propellant, the influence of insensitivity on the combustion law of propellant was studied by closed-cell burst test and shooting range test. The combustion numerical model of propellant- The method to determine the combustion characteristics of the insensitive drug was proposed and the internal ballistic characteristics of the insensitive propellant were calculated and calculated. The calculated results accorded with the changing law of firing in the bore and was in good agreement with the shooting test
