Effect of Branched Gap Synthesis Parameters on Mechanical Properties of Rocket Propellants

Abstract

An experimental minimum- smoke low-vulnerability rocket propellant composition was developed at DREV. The formulation contains phase stabilized ammonium nitrate (PSAN) as the oxidizer and an energetic binder based on branched glycidyl azide polymer (B-GAP). Different B-GAP polymers, obtained by varying some synthesis parameters, were incorporated into the formulation in order to study the effect on the mechanical properties of the resulting propellants. The reaction parameters investigated were the solvent end cleaving agent as well as the polyol used in the synthesis of 8-GAP. The study highlighted the fact that some experimental parameters selected for the polymer synthesis have a strong influence on the mechanical properties of the propellant processed with B-GAP.
