摘　　要：为实现直线多点同步起爆MEFP战斗部,对多路导爆索传扩爆组件开展相关研究。选用爆速精度较高的银导爆索以提高多点起爆同步性能,通过试验测定传扩爆组件的各起爆点的精确位置,并结合仿真加以分析。结果表明,采用该起爆装置技术方案(n+1)点起爆n层周向MEFP战斗部,有利于提高EFP飞行稳定性,缩小EFP飞散带宽,提高EFP动能,提升弹药作战效能。In order to realize the simultaneous initiation of the MEFP(multiple explosively formed projectile)warhead at multiple points in a straight line,relevant research has been carried out on the multi-channel detonating cord transmission and expansion component.The silver detonating cord with higher detonation velocity accuracy is selected to improve the synchronization performance of multi-point detonation.The precise position of each detonation point of the detonation transmission component is determined through experiments,and the analysis is combined with simulation.The results show that the use of the(n+1)point detonation of the detonating device technical solution to detonate the n layer circumferential MEFP warhead is conducive to improving EFP flight stability,reducing EFP flying bandwidth,improving EFP kinetic energy,and improving ammunition combat effectiveness.
