| 单个EFP在毁伤面积上存在一定的局限性。为扩大EFP毁伤威力和毁伤面积,本文研制了一种高初速的EFP战斗部,设计出一种含有46个EFP的平面分布式火力毁伤元。首先采用X光实验技术对弹丸进行X光拍摄,通过对X光照片的判读获取弹丸的外形尺寸和飞行速度,完成单个EFP战斗部的优化设计；然后在靶场对优化后的EFP战斗部进行侵彻实验,通过靶场回收得到弹丸的外形尺寸,采用测速靶得到弹丸的飞行速度,进一步验证所设计变壁厚药型罩形成高速弹丸的稳定性；最后将EFP战斗部按一倍战斗部直径的间距集成在一个由聚氨酯材料形成的平板上,采用高速摄影技术对起爆后弹丸的飞行轨迹进行拍摄,通过对高速摄影录像的判读,获取弹丸的飞行轨迹,由此判断弹丸在飞行过程中是否发生发散。实验结果表明,所设计的EFP弹丸飞行速度约为2200m/s并具有较好的密实性,火力毁伤元起爆后所形成的弹幕没有发生发散,且具有较好的飞行稳定性。本文设计的平面分布式火力毁伤元可根据对毁伤面积的要求调整布置,扩大了EFP的应用范围。 |

| Single EFP has certain limitations on the destruction area. In order to expand the destruction power and destruction area of EFP, a high muzzle velocity EFP warhead and a plane-distributed fire destruction element with forty-six EFPs were designed by authors. Firstly, the X-ray photo of projectile was taken by X-ray experimental technique, then the dimensions and flight speed of projectile were obtained by interpretation of radiograph, thus, the design optimization of single EFP warhead was completed. Secondly, penetration experiment of optimized EFP warhead was implemented on the range, so the outline dimension and flight speed of EFP were obtained by range recycling and velocity measurement targets, respectively. Thus, the stability of designed high-speed projectile with variable wall thickness liner was further verified. Finally, EFP Warheads were integrated on a polyurethane plate with double spacing of real diameter of an EFP Warhead. Flight path of projectile after initiation was photographed by high-speed photography，the flight path of projectile was obtained by high-speed photography video interpretation. The occurrence of projectile dispersion was judged based on above results. Experimental results show that the flight speed of designed projectile is about 2200m/s, and the projectiles have high compactness. The barrage formed by the fire destruction element after initiation does not disperse, and the projectiles have good flight stability. The plane-distributed fire destruction element can be adjusted according to the requirement of destruction area, which expands the application of EFP. |
