DETONATION VELOCITIES OF ''IDEAL'' EXPLOSIVES WITH INERT ADDITIVES
Abstract
A theoretical and experimental study of the covalance (alpha)-specific volume (V sub 2) relationship which was valid for pure explosives (AD-8032) was made for explosives with inert additives. Graphic comparisons of the results of 3 mixtures with pure TNT indicated an agreement over the mixture range considered. The relationship was used to make ideal thermohydrodynamic calculations for Tritonal, DNT, 60-40 cyclotol, pentolite, 60-40 Tetratol, 80-20 TNT-PETN, and pure NH4NO3. The predicted detonation velocities agreed well with available experimental data. A comparison was made of the calculated values of several TNT-salt mixtures under the assumptions that the NaCl vaporizes to NaCl gas and is inert. Detonation-velocity and pressure data indicated that a negligible amount of salt is vaporized in the salt granulations studied. Calculations of several thermohydrodynamic variables were made for mixtures of RDX and pentolite with salt. Experimental and theoretical detonation velocities were compared for explosives mixed with salt or glass beads. The calculated velocity-density relationships are given for RDX, TNT, and pentolite mixed with salt. The coefficient of compressibility for glass was assumed to be negligible. (See also AD-16379)
