EFFECT OF ALUMINUM ON THE RATE OF DETONATION OF TNT

Abstract

The rates of detonation of mixtures of TNT and aluminum in both the cast and pressed condition have been determined over a wide range of densities and percentages of aluminum. It was shown that the addition of aluminum to TNT in any proportion up to 40% decreases the rate of detonation. The mechanism of the explosive reaction is discussed. It is postulated that the aluminum remains chemically inert during its passage through the zone of decomposition of the TNT and causes a reduction of the rate of detonation by extracting thermal energy from the reaction zone. A Theory of Thermal Dilution is proposed which is based on a simultaneous application of the Hydrodynamic Theory, the Theory of Explosive Reactions, and the Theory of Heat Conduction.
