Abstract

For CHNO explosives, two new correlations of the form $P_{CJ}\;=\;8.7({\alpha}T_c')^{1/2}{\rho}_0^2-5\;and\;P_{CJ}\'=\'9.5({\alpha}T_c')^1/2{\rho}_0^2-9$ have been demonstrated, which relate detonation pressure, $P_{CJ}$; combustion temperature of the explosive in gas phase, $T_c$; combustion temperature of the explosive in crystalline state, $T_c'$; and the number of moles of gaseous products per unit weight of explosive, α; at initial density of the explosive, ${\rho}_0$. Experimental and semi-empirical PM3 procedures were used for the computation of $T_c$. Detonation pressures derived in this manner have a simple form without need to use computer code.
