Reaction Mechanisms of Energetic Materials in the Condensed Phase: Long- term Aging, Munition Safety and Condensed-Phase Processes in Propellants and Explosives

摘要

The achievements of this five-year project are summarized. The primary achievement is the development of a new paradigm to investigate the complex reaction processes that control the behavior of heterogeneous energetic materials in munitions throughout their life cycle. It is known as Concepts Methods and Protocols for Reaction Hierarchy and Network Development (CoMPReHND). Results from the decomposition of a high-nitrogen compound, triaminoguanidinium- (5,5')azobitetrazolate (TAGzT) and its interaction with RDX illustrate its use and provide an explanation for increased burn rates of propellants with TAGzT. The report summarizes work on the decomposition of BDNPA/F and several HMX-based explosive formulations: PBX9501, LX-04, LX-10, LX- 14 and EDC-37. The results on the HMX-based explosives suggest that Estane binder used in the PBX9501 and the LX-14 formulations may increase the rate of decomposition of HMX in these formulations compared to HMX by itself or in the other formulations. The report describes the development of the reaction modeling and kinetics (REMKIN) compiler and analysis tool, which provides a means to develop mathematical models of complex reaction processes. Finally, a report the JANNAF workshop on 'R&D Required to Implement New Ingredients in Munitions' and the development of a new paradigm to develop EM is described.
