A mission program named Extended Area Protection and Survivability was initiated at the U.S. Army Research Laboratory to demonstrate guided ammunition technologies to defend the battle space against any presented targets, such as mortars, rockets, and artillery. This report introduces the first step in the development of the guided ammunition system. It presents high-level physics-based simulations of a 60-mm projectile system. The topology of the initial projectile was developed on the basis of gun barrel specifications and certain aerodynamics characteristics. A three-dimensional finite element model was created to present the projectile system. Three different projectile configurations were analyzed with the LS-DYNA program and the results were compared. An acceptable deign demonstrated that the muzzle velocity reached only 85% of target value mainly because the launch package exceeded the desired mass by 25%. In addition, a characteristic centerline variation of a gun barrel was taken into account in this report. The outcome of the in-bore vertical displacements and accelerations attributable to the variation was found to be significant. Note that the structural configuration of the initial projectile is not optimal. Rigorous optimization efforts will be made on the system, particularly on the sabot component, in order to meet performance requirements.
