The desire to significantly reduce the weight of machine gun barrels while simultaneously increasing their operational life has led to the need to develop a transient heat transfer model that accurately addresses the thermal management problem while simultaneously supporting the execution of rapid trade studies of barrel geometry and material. To address this need, National Technical Systems Ordnance Sciences Division has created a detailed finite-difference based numerical model using the Mathematica software, developed and marketed by Wolfram Research, as the solution platform. This model solves the one-dimensional temperature profile through the thickness of the barrel at a specified axial location.
