The Gurney method is widely used in the conceptual design stage of explosive fragmentation warheads employed in various weapons systems. This method states that the peak fragment velocity $\left(V_0\right)$ is a function of the Gurney velocity ($\sqrt{2E_{\mathrm{G}}}$) and the charge-to-metal weight ratio ($C/M$). The current study is concerned with finding a practical approach for computing the Gurney velocity of pure and mixed high explosives which will eventually help warhead designers to select the best explosive to fulfill the needs of a particular mission. Using multiple regression analysis technique, a four-variable model was derived and used thereafter to estimate the Gurney velocity of aluminized and non-aluminized explosive formulations. The results show that the new model is particularly accurate in predicting the Gurney velocity of combined effects explosives, which are relatively a new class of high blast, high metal acceleration capability explosive compositions.

Gurney方法被广泛用于各种武器系统中的爆炸碎片战斗部的概念设计阶段。该方法表明峰碎片速度$（V_0）$ 是格尼速度（$\sqrt{2{Ë}_{\mathrm{G}}}$）和金属荷重比（$C/\mathrm{中号}$）。当前的研究关注寻找一种计算纯混合高爆炸药格尼速度的实用方法，这最终将帮助弹头设计人员选择最佳炸药以满足特定任务的需要。使用多元回归分析技术，得出了一个四变量模型，此后用于估算渗铝和非渗铝炸药配方的葛尼速度。结果表明，该新模型在预测复合效果炸药的格尼速度方面特别准确，这是一类新型的高爆炸，高金属加速能力的炸药成分。
