The thermal explosion temperature (T_b) was determined by heat explosion test and the drop height (H₅₀) was obtained by impact sensitivity test for 12 types of RDX-based aluminized explosives with different contents of RDX and aluminum powder respectively. The heat explosion parameters decreased to the lowest when RDX content reaches 89%(T_b, heat explosion activation energy(E_b) and logarithm of pre-expontential factor(lnA)), and drop energies (E_dr) were calculated with experiment data. The results show that the drop height (H₅₀) first fall down and then rise with the increasing of RDX contents. Additionally, it is found that a linear relationship exists between the drop energies (E_dr) and heat explosion parameters (T_b, E_b and lnA).
