Electrothermal-Chemical (ETC) Extensions to IBHVG2 With a New User's Tutorial

Abstract : IBHVG2, the computer code named for Interior Ballistics of High Velocity Guns, is a lumped parameter (zero dimensional) interior ballistics code which has been widely utilized to model solid propellant charges both nationally and internationally. Over the past 10 years a number of user options such as automated search routines and metric units have been added to the code. In this report we describe the extension of the code to allow the addition of electrical energy to the propellant gases to simulate electrothermal-chemical (ETC) guns. In addition, this report serves to update the original user manual and includes a description of the current input variables and sample output.
