Lagrange Gage Studies of Nonideal Explosives Containing NH4NO3
Abstract
Theoretical and experimental studies of planar detonation waves in Amatex 20 were performed to obtain a better understanding of the role of ammonium nitrate in the detonation process in explosives formulated from RDX, TNT, and AN. The theoretical work was performed to provide a more definitive and realistic treatment of steady-state detonation waves in such composite explosives. The treatment developed for such waves extends the classical Zelodovich-von Neumann-Doering (ZND) model for ideal detonation into a prototype model for nonideal detonation. The kinetic processes responsible for nonideal behavior were assumed to be incomplete decomposition of the slowest reacting explosive component, and the incomplete attainment of chemical equilibrium among the detonation products from the different explosive components. The experimental work was performed to obtain a more complete characterization of the detonation process in Amatex 20. The mean particle size of AN in the Amatex 20 charges was increased from the baseline value of appx 7 mm to a value of appx 2 mm. Multiple Lagrange particle velocity gage experiments were performed and analyzed to obtain a quantitative description of planar detonation in this coarse-grained Amatex 20.
