摘要
以硝化棉(NC)为点火药,装药密度为0.12 g/cm3,编号为1#、2#、3#、4#4种发射药为研究对象,采用密闭爆发器实验测试方法,研究点火压力的改变对发射药燃烧性能的影响。研究表明:随着点火压力的升高,发射药的点火延迟期和燃烧时间均缩短;点火压力越高,基于L-B曲线的燃烧渐增性也更好;4种发射药基于ψ-I/I'K曲线的燃烧渐增性强弱顺序为4#>1#>2#>3#。
The influence of the changing ignition pressure on the combustion properties was researched. the propellant ignition delay and combustion time is shortened with the increase of ignition pressure ; Under higher ignition pressure, progressive burning based on the dynamic activity curve is also strengthened; The progressive burning order based on φ - I/I＇K curves of the four propellants is 4# 〉 1# 〉 2# 〉 3#.
