Study on Low Burning Rate NEPE Propellant

Open publisher page 5 citations

Abstract

A low burning rate NEPE propellant were investigated by means of adding some burning rate inhibitors and adjusting its composition. The compatibility of additives with nitrite ester, combustion properties of the propellant and the standard specific pulse of Φ40 rocket motor were measured. It was observed that the burning rate of the propellant could be depressed by more bigger particle diameter AP , low ratio of NG/DEGDN, less AP content and presence of burning rate inhibitors. The burning rate under 4.0MPa could be 4.7mm/s, and standard specific pulse was 2239.3N·s/kg without additives.
