采用高速扫描相机及电探针测速法测量了具有相同铝含量的CL-20基和RDX基含铝炸药的拟定态爆轰波形及爆速,分析了炸药波阵面法向速度D_n与曲率κ之间的函数关系。结果表明,CL-20基含铝炸药的爆轰波阵面较RDX基含铝炸药的平坦,其法向爆速受曲率效应的影响也较RDX基含铝炸药的小。当κ>0.005 mm~(-1)时,其法向爆速的下降速率明显小于RDX基含铝炸药;当κ<0.005 mm~(-1)时,其法向爆速的下降速率略高于RDX基含铝炸药。 |

The steady state wave shapes and detonation velocities of CL-20-based and RDX-based aluminized explosives with same Al content were measured by a high speed scanning camera and electrical probe measuring velocity method.The function relationship between the normal velocity(D_n)and curvature(κ)of the detonation wave front of explosives was analyzed.Results show that the detonation wave front of CL-20-based aluminized explosive is flat than that of RDX-based aluminized explosive.The effect of curvature effect on normal detonation velocity of CL-20-based aluminized explosive is smaller than that of RDX-based aluminized explosive.Whenκ> 0.005 mm~(-1),the reduced rate of D_n of CL-20-based aluminized explosive is obviously less than that of RDX-based aluminized explosive.Whenκ<0.005 mm~(-1),the reduced rate of D_n of CL-20-based aluminized explosive is slightly higher than that of RDX-based aluminized explosive. |
