摘　　要：为了提高聚能装药战斗部从空中打击水中目标的准确性,建立了杆式射流从空气中成型至射流水下侵彻靶板全过程的分阶段递进式数值计算模型,并通过静破甲试验校核了计算模型,提高了计算模型的精度,误差为5%以内。试验中采用通断测速网靶测出了聚能射流入水前、入水后以及着靶前的速度,其最小误差率为0.39%,平均误差率为4.16%。研究表明:杆式射流入水前和入水后的速度呈线性减小,着靶前速度呈线性增大;杆式射流在水中的破甲深度随着空气炸高的增大,有先增加后减小的变化规律;聚能装药在水中的最佳炸高为4.89倍的装药直径,水中最大的侵彻深度为1.3倍的装药直径。为聚能装药战斗部在空气中隔水打击水中目标的研究提供了依据与参考。In order to improve the accuracy of a shaped charge warhead striking underwater targets from air,a phased progressive numerical calculation model for the whole process of the rod jet from forming in air to underwater penetrating into the target plate was established.The calculation model was verified by static penetration test,the accuracy of the calculation model,was further improved,with the error within 5%.In the experiment,the velocities of the shaped charge jet before entering the water,after entering the water and before reaching the target were measured by using an on-off velocity measurement network.The minimum error rate is 0.39%and the average error rate is 4.16%.Through the study,it is found that the velocity of the rod jet before and after entering the water decreases linearly,and the velocity before contacting the target increases linearly.The penetration depth of the rod jet in water increases first and then decreases with the increase of air explosion height.The optimum explosion height of the shaped charge in water is 4.89 times the charge diameter,and the maximum penetration depth in water is 1.3 times the charge diameter.The results provide a basis and reference for the research on the shaped charge warhead in air to hit underwater targets.
