Analysis of Deflagration to Detonation Transition in High-Energy Solid Propellants

Abstract

Increasing the nitramine content of solid rocket propellants increases the overall performance of the system as well as the sensitivity to detonation by shock initiation. Under certain circumstances Deflagration to Detonation Transition (DDT) can occur in high-energy solid propellant that has been granulated. The work presented in this report represents an effort to analyze three distinct ways in which high-energy solid propellant can undergo a DDT. The emphasis of the research is on the transient events prior to the detonation as well as the steady state detonation conditions. The system of partial differential equations describing one-dimensional, two-phase, reactive flow are solved by a Method of Lines (MOL) computer solution technique. Predictions for CJ(Chapman - Jouguet State) properties, detonation run-up distance and detonation velocity compare favorably with experimental data and predictions made using the TIGER chemical equilibrium computer code. Originator supplied keywords include: Analysis of Shock initiation, and Porous explosive DDT.
