摘要
为研究半预制破片PELE弹丸对武装直升机的毁伤效能,选取代表性的阿帕奇武装直升机为研究对象,建立了阿帕奇武装直升机关键部件驾驶舱和发动机舱的等效模型,在此基础上应用ANSYS/LS-DYNA就半预制破片PELE弹丸对阿帕奇武装直升机的毁伤效能进行了数值分析。结果表明:半预制破片PELE弹丸能有效穿透阿帕奇武装直升机的防护装甲,在穿透防护靶后弹丸壳体大面积碎裂,产生大量具有较高轴向剩余速度和一定径向飞散速度的破片,形成一个大面积的破片场,这些破片及弹丸剩余部分可对武装直升机内部人员及仪器设备造成有效毁伤,极大地增强了PELE弹丸的毁伤效能。
The representative Apache armed helicopter is chosen as the research object to study the half-fragmented PELE＇s damage efficiency of armed helicopters,and numerical simulations are carried out based on the equivalent models of the Apache armed helicopter＇s key parts established in this paper.The results indicate that the half-fragmented PELE projectile can penetrate the defensive armored plate efficiently,the jacket of the projectile fractures into fragments in large area,and the fragments with certain axial and radial velocity have the capability to damage the pilots and equipments inside the armed helicopter,and the PELE projectile＇s damage efficiency is therefore obviously enhanced.
