摘要：

为研究黑索今（RDX）基含铝炸药水下爆炸性能，在户外水池中开展了不同药量和含铝量的RDX基炸药水下爆炸实验。采用水下高速摄影技术拍摄水下爆炸气泡脉动全过程，通过压力传感器对水中压力进行实时测量。在该实验条件下，首次拍摄到RDX基含铝炸药水下爆炸过程中二次反应现象，证明铝粉的二次反应是毫秒量级的。根据实验数据，对比分析了不同含铝量下RDX基含铝炸药水下爆炸过程中气泡脉动特性和水流场压力特性。实验结果表明：在气泡膨胀初期和收缩末期都发生了铝粉的二次反应；铝粉的二次反应显著增大了RDX基含铝炸药气泡的脉动能力；铝粉的二次反应对冲击波峰值的影响很小，对气泡脉动压力峰值的影响很大；铝粉的二次反应明显影响了水下爆炸的能量结构分布。

Abstract:

To investigate the underwater explosion performance of RDX-based aluminized explosive, the underwater explosion experiments for RDX-based aluminized explosives with different charge masses and aluminum contents were carried out in outdoor pools. The process of generation, expansion and contraction of underwater explosion bubbles was observed through the high-speed camera placed in water, and the pressure history of shock wave was measured by a pressure sensor. Under the experimental conditions, the secondary reaction process of powdered aluminum for RDX-based aluminized explosive during underwater explosion was captured by the high-speed camera firstly, which indicates that secondary reaction process of powdered aluminum is in the order of milliseconds. According to the experimental data, the pressure in flow field and the bubble pulsation were analyzed. The experimental results indicate that the secondary reaction of powdered aluminium occurs in both the initial stage of bubble expansion and the end of bubble contraction. The secondary reaction of powdered aluminium significantly increases the pulsation ability of bubble. The secondary reaction of powdered aluminium has little effect on the peak value of shock wave and great influence on the peak value of bubble pulsation. The secondary reaction of powdered aluminium obviously affects the energy structure distribution of underwater explosion. Key
