Dual Thrust Extruded Double Base (EDB) propellant was created by the High Energy Materials Research Laboratory (HEMRL) for the Portable Anti Tank Guided Missile. The propellant has successfully completed several flight trials in both static and dynamic conditions, meeting all requirements. A Dual Thrust EDB propellant grain of high energy and high burn rate is used to create the necessary pressure-time and thrust-time profile as well as the maximum range of the missile. This is accomplished by utilising unique burn rate modifiers in the EDB propellant formulation.

All of the ballistic requirements were being met by the propellant performance. Conventional extruded double base (EDB) propellant and composite propellant processing are not the same as the technology used to make dual thrust EDB propellant. The propellant’s low sensitivity to pressure and temperature makes it distinctive. This guarantees little propellant fluctuation.

These qualities can be attained by HEMRL-optimized manufacturing processes. HEMRL has determined the propellant composition utilising locally sourced materials and unique burn rate modifiers. Propeller development is now finished following successful validation and development testing. Dual thrust EDB propellant is made using a number of procedures that were developed by HEMRL throughout development, including the preparation of NC-NG paste, kneading, rolling, extrusion, annealing, and maturation, followed by machining and inhibiting processes.

The HEMRL-developed EDB propellant is now prepared for manufacturing/production agencies to take it to test.
