Burning Rate of Solid Propellant Ingredients, Part 1: Pressure and Initial Temperature Effects

Abstract

Burning rate data are presented with respect to initial temperature and pressure for three compounds that are currently used in propellant and explosive formulations. The dependence of burning rate on initial temperature and pressureispresented forammonium perchlorate(AP), HMX, and RDX.Data foringredients being considered for advanced propellants, such as CL-20, ammonium dinitramide (ADN), and hydrazinium nitroformate (HNF) are also presented and compared to the more traditional compounds. These ingredients are all capable of selfdee agration,andtheirbehavioroftencontrolsthebehaviorofthepropellantsinwhichtheyarethemainingredients.
