Modeling of Rigidized Gun Propelling Charges

Abstract : The TDNOVA code was developed to simulate the interior ballistics of multi-increment propelling charges by means of a numerical solution of the equations of two-dimensional, two-phase flow. The present work describes extensions to the code, primarily to permit the simulation of rigidized stick propellant charges, and secondarily to explore the ballistic consequences of heat loss to the tuber and of slow gas-phase kinetics.
