Manganin pressure transducers and probes were respectively used to measure the detonation pressure and detonation velocity of RDX-based aluminized explosive with different Al content.Two relationships of detonation pressure and detonation velocity vs Al content,were fitted,and the influence of Al content on detonation pressure and detonation velocity of RDX-based aluminized explosive was analyzed.The result shows that the detonation pressure and detonation velocity reduce linearly with increasing of Al content,based which we gain the A(x) value of PC-J=A(x)ρ0D2 when Al content changes from 0 to 40%,and the relationship between A(x) value and Al content were fitted.Eventually,the equation between detonation pressure and detonation velocity was figured out.
