A workshop with the objective to view the current state of the art of energetic-material combustion models within the context of future requirements of gun interior-ballistics (IB) models was held at the U.S. Army Research Laboratory (ARL), Aberdeen Proving Ground, MD, on 9 and 10 April 96. The workshop was motivated by the recognition that modeling and simulation will be an essential cost-saving and time-saving tool in the design, development, testing, and evaluation of future gun-propulsion systems, and that, under current funding constraints, research on the underlying fundamentals must be carefully directed toward the most critical technology barriers. To facilitate this process, a perspective was presented on the fundamental physics and chemistry currently utilized in IB codes (XKTC, etc.) and the extensions planned for advanced codes (the NGEN family). The state of the art in fundamental descriptions of energetic-material combustion was then summarized and discussed with the intent of giving focus to those issues that could impact the future development needs of the IB research community.

A multidisciplinary modeling approach is used to study the dynamic response of a notional telescoped ammunition projectile to gun chamber pressure dynamics generated by a densely packed solid propellant charge during gun launch. Since material stress imposed on the ammunition could potentially damage the projectile or its payload, a detailed knowledge of the peak stress is essential in the ammunition design process. The modeling approach begins with the Army's interior ballistics code ARL-NGEN3 predicting ignition, flamespreading and combustion of the solid propellant charge. Following this, the structural mechanics code EPIC simulates the response of the projectile to the pressure dynamics computed by the ARL-NGEN3 code. The results are analyzed in order to develop a comprehensive understanding of the in-bore behavior of the projectile.
