聚能射流的跳弹角

Ricochet Angle of a Shaped Charge Jet

为弥补原有射流侵彻大倾角靶板时射弹跳弹角计算方法的不足,给出了考虑聚能射流和靶板的可压缩性的聚能射流跳弹角的计算方法,并进行了试验研究。对计算结果与实验结果进行了对比分析,分析结果显示,射流的跳弹角不仅与射流速度、密度、声速和压缩率等物理参数有关,还与靶板材料的密度和声速等参数相关。计算结果和试验结果符合良好。

To remedy the deficiencies of the calculation method of ricochet angle of jet while jet penetrating big-dip-angle target, the method for calculating ricochet angle was presented considering shaped charge jet and target material compressibility,and the method was studied by experiment. Results show that ricochet angle is related with the physical parameters of jet, such as velocity,density,sound velocity and compressible ratio,and related with the target density and sound velocity, etc. The results calculated by the presented method agree well with the experimental data.
