ABSTRACT: The objective of this program is to tailor and focus the capabilities of an existing software package for prediction of the rapid transient events following ignition of rocket-propelled munitions, as well as the firing of small caliber weapons. These events differ from missile plumes in that they are very fast transient events occurring at the time of weapon firing. These events are critical because they provide the first, and often the most intense detectable signal that a weapon has been fired. The aim of this work is to predict the flow-field external to these devices in sufficient detail to allow the accurate prediction of the electro-optical signature of the devices via post-processing the flow-field simulation results for integration with a radiative transfer model. This will be accomplished by upgrades and adaptation to existing software tool, and extensive validation of the software to determine the optimum numerical modeling approach, including chemical reaction mechanisms required for small caliber ammunition firing and rocket-propelled grenades. The approach will also encompass tracer bullets. BENEFIT: The Arnold Engineering Development Complex (AEDC) Advanced Missile Signature Center (AMSC) in support of the Center for Countermeasures (CCM) is developing a Hostile Fire Signature (HSIG) model to simulate dynamic EO signatures of small caliber weapons and rocket-propelled munitions. The HSIG program"s need is to develop a physics-based computer model to produce EO signatures for muzzle flash from small caliber weapons and rocket propelled grenades (RPG) among other weapon types. The software developed in this program will provide the necessary model. Beyond the specific application to the HSIG program the software has significant potential application in numerous DoD and industrial programs that involve missiles, rockets and other space vehicles plumes and associated signatures.
