Abstract
An experimental minimum-smoke low-vulnerability rocket propellant fomulation was developed at DREV. This 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 and cleaving agent as well as the polyol used in the synthesis of B-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 G-GAP.
