A new pathway has been introduced to predict detonation pressure of CHNO and CHNOAl explosives. Although aluminized explosives can have Chapman-Jouguet detonation performance significantly different from those expected from existing thermodynamic computer codes for equilibrium and steady state calculations, new correlation can also be used here. Molecular structures of CHNO and CHNOAl explosives are the only necessary parameters that would be needed in this new scheme. There is no need to use heat of formation or any experimental data. Besides, elemental compositions of CHNO and CHNOAl explosives rather than assumed detonation products are essential input parameters. Predicted detonation pressures for CHNO explosives are compared with experimental data as well as computed results gained by complicated computer code using BKWR and BKWS equations of state so the new method shows the best results. Also, the calculated results for CHNOAl explosives indicate good agreement with the measured data as compared to estimated results of BKWS-EOS using full and partial equilibrium.
一种预测CHNO和CHNOAl炸药爆轰压力的新途径已被引入。尽管含铝炸药的查普曼-朱盖特爆轰性能可能与现有用于平衡和稳态计算的热力学计算机代码所预期的有显著差异，但这里也可以使用新的关联式。CHNO和CHNOAl炸药的分子结构是该新方案中唯一需要的必要参数。无需使用生成热或任何实验数据。此外，CHNO和CHNOAl炸药的元素组成而非假定的爆轰产物是至关重要的输入参数。将CHNO炸药的预测爆轰压力与实验数据以及使用BKWR和BKWS状态方程的复杂计算机代码获得的计算结果进行了比较，因此新方法显示出最佳结果。此外，与使用完全和部分平衡的BKWS-EOS的估计结果相比，CHNOAl炸药的计算结果与测量数据显示出良好的一致性。
