起爆点个数对FAE战斗部爆炸威力影响研究

Study on the Influence of the Number of Initial Detonation Point of FAE to Explosive Power

通过对某FAE战斗部进行三组相同装药量不同起爆点个数的静爆实验,起爆点个数分别为单点,两点和四点,研究起爆点个数的不同对FAE战斗部爆炸威力的影响。实验结果表明,该FAE战斗部爆炸场超压随着起爆点个数增加而降低(从单点到四点降低了48%～52%),FAE战斗部爆炸场冲量随着起爆点个数增加而提高(从单点到四点提高了8%～22%)。由此可知,对于以冲击波冲量毁伤目标的方式,战斗部采用多点起爆可以提高毁伤效果。

The influence of the number of the initial detonation point of FAE to explosive power was studied through the method of the blast experiment, which has three same charge groups of FAE warhead with different number initiating points, including single point, two points and four points. The results showed that the shock wave overpressure of explosion of FAE warhead would decrease with the increase of the number of initiating points （ from a single point to four points reduced by 48 % - 52 % ）. While the shock wave impulse of explosion of FAE warhead would increase with the increase of the number of initiating points （from a single point to four points increased by 8 % -22 % ）. It can be known that the multi point initiation of FAE warhead will improve the damage effect if the target is killed by the impact wave impulse.
