Insensitive Munitions Modeling and Simulation

Insensitive munitions (IM) design and testing for propulsion systems is hindered both by high test costs and the complexity of propellant responses to IM stimuli. Modeling and simulation tools for predictions of IM hazards are under development that characterize many of the pertinent phenomena, including damage sensitization to reaction and delayed-onset detonation. Such tools can provide many benefits to the development of IM propulsion systems. We will collaborate with the Thermal and Reactive Processes Department at Sandia National Laboratories, to survey these computational tools, exercise them for representative scenarios, assess their current utility for rocket and missile propulsion system IM predictions, and make recommendations for tool improvements to enhance their capabilities. Our innovation will be a streamlined process for using existing model frameworks in propulsion system IM assessments.
