| Abstract: | In order to study the rules of explosive energy release and the structure of explosive energy output, the detonation heat and detonation velocity of five kinds of aluminized thermobaric explosives were measured. The explosion energy of RDX-based aluminized explosive containing 30% (mass fraction) Al was measured by adiabatic detonation calori-meter under different atmosphere: vacuum, 0.1 MPa nitrogen, 0.1 MPa air and 1.0 MPa oxygen. The heat of explosion and combustion were calculated theoretically. The results show that the detonation velocity reduce linearly with the increa-sing of aluminum content. The detonation heat increases first and then decreases with the increasing of aluminum content, and the heat of explosion reaches a maximum value when the aluminum content is 40%. The explosion energy of the sample increased gradually in sequence of vacuum, 0.1 MPa nitrogen, 0.1 MPa air and 1.0 MPa oxygen; the increase of environmental pressure and oxygen content results in the increase of explosion energy. Explosion energy in oxygen-enriched environment can quantitatively characterize the combustion heat of explosives. Detonation supporting heat of the sample accounts for 9.8%-26.4% of the combustion heat, and the detonation heat accounts for 34.5%-50.0% of the combustion heat, and both of these parameters decrease with the increase of aluminum content. |
