EQUATIONS OF STATE OF SILICON, BORON, AND HALOGEN SPECIES FOR ACCURATE DETONATION CALCULATIONS

摘要

The combined effects aluminized explosives PAX-29, PAX-30, and PAX-42 developed by the U.S. Army Armament Research, Development and Engineering Center (ARDEC) have been demonstrated to achieve excellent metal pushing and high-blast energies in both cylinder test and warhead configurations The detonation behavior of additional explosive compositions is being investigated using the Jaguar thermochemical equation of state in conjunction with experimental data for these systems. For these studies, accurate equation of state parameters are required for a wide range of gaseous, liquid, and solid explosive components and reaction products. The Jaguar procedures include the capabilities to accurately calculate cylinder velocities and other detonation properties with an analytic cylinder test model. The analytic cylinder test model has been recently updated to include eigenvalue detonation theory and associated adiabatic expansion from the fully reacted Hugoniot weak point. The Jaguar property library has been expanded to include additional gaseous, liquid, and solid components and detonation products. New Exp-6 parameters for gaseous substances have been established by analyses of Hugoniot data for the actual species or for reactants which decompose into these compounds. Parameters for additional condensed species were also established from Hugoniot and volumetric data under shock compression conditions. Comparisons are performed with data for explosives and compounds containing the elements investigated to determine the accuracy of calculated detonation properties with the established equation of state parameters.
