Two new correlations for predicting detonating power of CHNO explosives

Abstract

For CHNO explosives, two new correlations of the form PCJ = 8.7(αTc)1/2ρ02-5 and PCJ = 9.5(αTc1)1/2 ρ02-9 have been demonstrated, which relate detonation pressure, CJ; combustion temperature of the explosive in gas phase, Tc; combustion temperature of the explosive in crystalline state, Tc1; and the number of moles of gaseous products per unit weight of explosive, α; at initial density of the explosive, ρ0. Experimental and semi-empirical PM3 procedures were used for the computation of Tc. Detonation pressures derived in this manner have a simple form without need to use computer code.
