Abstract
Abstract : In a previous report, a lumped parameter code for regenerative liquid propellant guns was described. Since then improvements have been made in the governing equations. A number of options have been added to the code, and some options have been removed. This report is an update to the description of the regenerative liquid propellant in-line gun code. The governing ordinary differential equations for the lumped parameter model of a regenerative liquid gun are given. The different options and assumptions are described. The equations are solved numerically using EPISODE, an efficient and robust computer code for the integration of ordinary differential equations. An example is given where the code is compared to an experimental gun firing, and the process of choosing reasonable input parameters is discussed.
