Relationship Between Normal Velocity and Curvature of Detonation Wave Front for CL-20-based Aluminized Explosive

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(Dn)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.Whenκ0.005mm-1,the reduced rate of Dnof CL-20-based aluminized explosive is obviously less than that of RDX-based aluminized explosive.Whenκ0.005mm-1,the reduced rate of Dnof CL-20-based aluminized explosive is slightly higher than that of RDX-based aluminized explosive.
