Effect of Aluminum Content on Detonation Heat of RDX-Based Aluminized Explosives

为了研究铝粉含量对含铝炸药爆热性能的影响,以RDX基含铝炸药为研究对象,分别通过理论计算和爆热测试,得到了RDX基含铝炸药的爆热结果,重点分析了混合炸药体系铝氧摩尔比对爆热的影响规律。结果表明:RDX基含铝炸药的爆热随着铝氧摩尔比的增大以三次多项式规律变化,呈先增大、后减小趋势;爆热最大时,炸药体系的铝氧摩尔比为0.8。

RDX-based aluminized explosives were selected as the research object to study the effect of aluminum content on detonation heat performance of aluminized explosives. Detonation heat of RDX-based aluminized explosives was obtained by theoretical calculations and detonation heat tests, and the influence of molar ratio of aluminum to oxygen of the mixed explosive system on the explosion heat was analyzed. Results show that detonation heat of RDX-based aluminized explosives changed with a cubic polynomial law as molar ratio of aluminum to oxygen increases, molar ratio of aluminum to oxygen which firstly increases and then decreases. When molar ratio of aluminum to oxygen is 0.8, the detonation heat reaches the maximum.
