Initial Development of Core Module of Next Generation Interior Ballistic Model NGEN
Abstract
Gun Propulsion systems of current interest include the traditional solid propellant (SP) designs, regenerative liquid propellant (RLP) designs and various electrothermal-chemical (ETC) designs. Presently, each of these systems is simulated by dedicated computer codes which are not readily extendible to the other systems. It is a goal of the Army Research Laboratory to develop a Next-Generation code which subsumes the capabilities of all existing codes into a structure which is modular and readily transportable from one propulsion engineer to another as well as from one computer architecture to another. The present report describes progress in the development of such a code referred to as NGEN. We present an algorithm to integrate the properties of the products of combustion in the presence of nonuniform geometry using the LCPFCT methodology on a structured rectangular mesh. Only those cells which are intercepted by bounding surfaces are given special treatment. This continuum flow solver is coupled to a Large Particle Integrator which determines the state of the propellant grains in a solid propellant charge. The operability of the code is illustrated by reference to two simulations, one for a 155-mm howitzer and one for a 120-mm tank gun.
