RDX基含铝炸药水中爆炸近场冲击波特性

通过水中爆炸试验,得到了RDX基含铝炸药在不同比例距离((-R))处的水中冲击波峰值压力、冲量和冲击波能.结果表明,在测试范围内,(-R)＜1.5 m/kg1/3,Al的质量分数为10%～20%时,冲击波峰值压力基本不变;(-R)≥1.5 m/kg1/3时,Al的质量分数为0～30%时,冲击波峰值压力基本不变.测试范围内,Al的质量分数为20%～30%时,冲量基本不变;Al的质量分数小于20%,冲量随Al含量的增加不断增大.(-R)＜1.0 m/kg1/3时,冲击波能随比例距离的增加而不断衰减;(-R)≥1.0 m/kg1/3时,冲击波能随比例距离的增加基本保持不变.(-R)=0.79 m/kg1/3(药柱18倍半径处)时,冲击波能量利用率只有25%左右,初始冲击波能损失了近1/2～3/5.

Underwater Shock Wave Characteristics of RDX-based Aluminized Explosives in Near-field Range

Shock wave peak pressure,impulse and shock wave energy of RDX-based aluminized explosives were obtained at different scaled distance by underwater explosion test.The result indicated that shock wave peak pressure was not influenced with Al contents of 10%-20% in the scaled distance range smaller than 1.5 m/kg1/3.Shock wave peak pressure was nearly constant by Al contents up to 30% in the scaled distance range larger than 1.5 m/kg1/3.Impulse was not influenced with Al contents of 20%-30% in the measured scal...
