Method of making a propellant grain containing metal wire staple
Abstract
Abstract STAPLE-CONTAINING PROPELLANT PELLET GRAINS ARE PREPARED BY INTIMATELY MIXING METAL STAPLES WITH A BINDER, PLASTICIZER AND OXIDIZER, FORMING THE MIXTURE INTO SMALL PELLETS WITH LENGTH APROXIMATELY EQUAL TO DIAMETER, MIXING THE STAPLE-CONTAINING PELLETS WITH ADDITIONAL PROPELLANT INGREDIENTS AT A PROPORTION SUCH THAT THE STAPLE-CONTAINING PELLETS COMPRISE 5 TO 70 WEIGHT PERCENT OF THE MIXTURE TO FORM A VISCOUS SLURRY, CASTING THE SLURRY AND CURING THE RESULTING GRAIN. BURNING CHARACTERISTICS AND PERFORMANCE ARE SUBSTANTIALLY IMPROVED OVER GRAINS PREPARED BY PREVIOUS SLURRY CASTING METHODS, BECAUSE THE STAPLES ARE RANDOMLY ORIENTED AND NOT ALIGNED PARALLEL TO THE MOTOR CASE WALL OR MOTOR MANDREL.
