摘　　要：为研究不同材料MEFP战斗部对典型无人机的侵彻性能,以代表性的"捕食者"无人机为研究对象,建立其关键部位的等效模型。选紫铜、铁和钢的MEFP战斗部用ANSYS/LS-DYNA对无人机等效靶的侵彻性能进行数值分析。结果表明:3种材料的MEFP战斗部均能穿透"捕食者"无人机的防护装甲,但对靶板的开孔直径、轴向剩余速度不同,可有效毁伤"捕食者"无人机内部仪器设备,使其丧失作战能力甚至解体。In order to study the penetration performance of MEFP warhead against typical unmanned aerial vehicle(UAV)withdifferent materials,the representative "Predator" UAV was selected as the research object,and the equivalent model of the keyparts of "Predator" UAV was established. The penetration performance of three kinds of MEFP warheads made of copper,ironand steel was studied on the equivalent target of UAV. On this basis,the penetration performance of different materials of MEFPwarheads on UAV was numerically analyzed using ANSYS/LS-DYNA. The results show that three kinds of materials of MEFPwarhead can effectively penetrate the predator drone protective armor,but the target plate hole diameter,the axial residualvelocity,divergence angle of projectile are different,the projectile to predator drone internal cause equipment damageeffectively,which make the UAV loss of capability or even collapse.
