Abstract In this paper, production of a double base propellant grains embedded with continuous metal wires by the screw extruder is investigated. The factors effecting the burning rate of the grains are analyzed and selection of suitable metal wires are discussed. Also, manufactured propellants with embedded metal copper, brass and steel wires (diameter=0.25 mm) were tested by Crawford Bomb method. By this process, the continuous metal wires embedded in grain are made straight and arranged properly to meet the design demands. The results showed that axial burning rate of the end-burning grain embedded with one continuous metal wires of 0.25mm diameter is 3.9 times as great as that of the propellant matrix. Also the torsion and rupture in the grains don’t occurred using embedded metal wire.
