Copper Chromite as Ballistic Modifier in a Typical Solid Rocket Propellant Composition: A Novel Synthetic Route Involved

Present report emphasises the importance of employing a nano-copper chromite having an excess cupric oxide (CUCRO) as a ballistic modifier in a typical solid rocket propellant (SRP) composition. The CUCRO synthesised from a modified combustion route through decomposition of the alginate mixed metal complex is employed in the present investigation. The changes occurring in the mechanical properties of the propellant strands on addition of the CUCRO modifier are studied. Different morphologies are observed, which contribute towards the toughened propellant composition. The ballistic studies are undertaken in the presence and absence of CUCRO.
