All Department of Defense DOD military services use a 2.75-inch rocket system, produced by a conventional batch method that produces large amounts of waste propellant, nitroglycerin, and process water, and are labor intensive. This project sought to demonstrate a lower cost manufacturing process that reduces the amount of waste and pollution generated in the manufacture of the Mk 90 double-base propellant grain used in the Mk 66 2.75-inch rocket system. The new process explored the use of a continuous shear roll mill and twin screw mixerextruder to reduce the propellant scrap, nitroglycerin emissions, and touch labor while increasing safety by utilizing remote control technology.
