Composite explosives containing aluminum/ammonium perchlorate (Al/AP) are widely used for blasting cut of old warship, blasting droll and decoupled charge of blast underwater. The available complex computer codes and empirical methods cannot usually provide a reliable estimation of detonation velocities of explosives containing Al/AP. This work introduces a reliable method for the desk calculation of detonation velocity. The percent of the reacted Al with detonation products and decomposition of AP, as well as composition of the detonation products, are specified according to the distribution of oxygen atoms between Al, C(s), CO(g) and H₂(g). The values of the mean absolute percentage error (MAPE) of the new model are lower than one of the best available methods for CHNO explosives (260 experimental data) and CHNOFCl explosives (50 measured data). For composite explosives, CHNOFClAl and CHNOFClAlAP, the MAPE value of the new model is 3.50, corresponding to 55 experimental data, which is much smaller than the MAPE values of the BKW computer code (8.37) and the comparative empirical model (14.20).

与最佳可行方法相比，评估非理想铝/高氯酸铵复合炸药性能的简单方法

含铝/高氯酸铵（Al / AP）的复合炸药被广泛用于旧军舰的炸药切割，炸药拖拉和水下炸药的解耦装药。可用的复杂计算机代码和经验方法通常不能可靠地估计含Al / AP炸药的爆炸速度。这项工作引入了一种可靠的方法来进行爆轰速度的桌面计算。根据Al，C（s），CO（g）和H ₂之间的氧原子分布，确定与爆炸产物和AP分解的Al发生反应的百分比以及爆炸产物的组成（G）。新模型的平均绝对百分比误差（MAPE）值低于用于CHNO炸药（260个实验数据）和CHNOFCl炸药（50个测量数据）的最佳可用方法之一。对于复合炸药CHNOFClAl和CHNOFClAlAP，新模型的MAPE值为3.50，对应于55个实验数据，比BKW计算机代码（8.37）和比较经验模型（14.20）的MAPE值小得多。
