钢模拟爆炸成形弹丸(EFP)飞行特性及对大间隔靶的侵彻实验

为考察现有设计水平下，爆炸成形弹丸EFP（Explosively Formed Projectiles)的飞行特性及侵彻威力，用37火炮发射长径比为1．5的钢EFP的模拟弹丸，其着靶速度在1．3km左右，对大间隔的多层A3薄钢靶板进行侵彻，弹丸贯穿了5层靶，质量损失较小。利用高速摄影考察了EFP在靶间的飞行姿态变化，分析了EFP对多层大间隔靶侵彻的作用过程及其机理。实验结果和分析表明，所设计的EFP具有较为理想的飞行稳定性，对多层间隔侵彻能力强 ，为设计攻击舰艇等装甲目标的战斗部装药结构提供了较重要的参数。

Experiment on Flight Characteristics and Penertration against Spaced Targets with Big Spacing of EFP Warhead

To study the flight characteristics and penetrating power of EFP of the present desiging level, steel EFP simulants with L/D=1.5 were launched at impact velocities of 1.3 k/s or so by a cannon. They penetrated thin A3 steel spaced targets with big distance. The pills perforated five layer targets, and with little loss of its mass. High speed photography was used to investigate the flight characteristics of the EFP between targets. The paper also analyzes the process and principle of EFP against multiplayer targest with big distance between each other to a certain extent. The results obtained from the analysis of the experiments indicate that the EFP designed has good stability of flight and penetration against spaced targets and provide important parameters for designing charge configuration of warheads against armour targets such as naval ships.
