大炸高下爆炸成型弹丸的试验研究

摘要

Aiming at flight characteristics and penetration property of EFPs at large stand-off distance,experiments were carried out with different liner thickness of EFP warhead. A serial of grid targets are used in the flight trajectory to investigate the flight characteristics of the EFPs, and a suitable thickness armor steel target at the end of the trajectory is used to investigate the penetration property of the EFPs.Meanwhile, the simulation calculation was carried out to verify the test result. The results showed that when the thickness of liner is 0.046 times of charge diameter , both the flight characteristics and penetration property of the EFP is best, and the test result is accordant with the simulation result well.%为进一步优化设计EFP战斗部，试验研究了3种不同药型罩壁厚的EFP战斗部在大炸高下的飞行稳定性能和侵彻威力情况，对比分析穿过纱网靶后留下的孔形及对装甲钢靶板的侵彻效果，并通过仿真计算进行验证。结果表明：药型罩壁厚为0.046D k时形成的EFP不仅飞行稳定性好，且穿透了一定厚度的装甲钢靶板，试验结果与仿真结果吻合较好。
