Non Energetic Binder Application for RDBP Propellant Based Large Caliber Munition (MKB)

Double base propellant (DB) to support high-speed rocket experienced problems DB propellant industry is not yet available in Indonesia. DB propellant material in Indonesia is propellant for large caliber munitions (MKB) that are different shapes and specifications. This research aims to converte large-caliber munitions (MKB) to a rocket RDBP propellant by reshaping and adding binders to MKB. RDBP propellant made by mixing MKB with a binding agent (binder), then casted to propellant RDBD with a diameter of 5mm. Propellant RDBP then measured the burning rate, specific impulse (Isp), and its mechanical properties. The research variables are the type of binder used (polyethylene, polyvinyl chloride) and its molecular weight. The results showed that the molecular weight binders positively effect on the mechanical properties of the propellant RDBP. Polyethylene (PE) and polyvinyl chloride (PVC) qualify as a binder (binder) to make RDBP propellant, wherein the propellant mechanical properties produced excellent (above 32 MPa), but RDBP propellant based PVC can not pass the ballistic requirement. The burning rate of RDBP propellant can reach a speed of 1.0 cm per second (above the threshold burning rate as required) by using the binder 5-10%.
