双组分炸药装药水下爆炸的冲击波峰压场研究

针对目前水下武器战斗部为单一组分装药模式,提出高低能量不同的双组分炸药装药模式. 从理论研究、实验分析和数值模拟3个方面对双组分炸药装药在水下后端面起爆的爆炸威力场规律进行了分析研究. 结果表明,双组分炸药装药的近场冲击波超压略有增加,在中场范围冲击波超压分布变化不大,可为水下双组分装药战斗部威力场设计提供参考.

Study on the Pressure Field of Underwater Explosion with Two-Component Explosive Charge

To the single-component explosive charge in underwater weapon warhead, a new warhead charge consisting of two-component with high and low explosive energy is proposed. Based on the theoretical analysis, experimental measurement and numerical simulation, the data in near interface water field of the two-component explosive charge is measured and analyzed. The conclusions show that the shock wave pressure has a higher peak pressure in near water field, and then it keeps at the same level in the mid-distance rang. These conclusions are useful for the determination of shock pressure field of a underwater two-component warhead.
