  • Process for additively manufacturing discrete gradient charges
    Patent number: 11040924
    Abstract: A discrete gradient charge that has a discrete first hollow cylindrical layer of a solid first fuel, which is about 85% by weight fine aluminum powder having a median diameter of about 3.5 microns. There is a discrete second hollow cylindrical layer of a solid second fuel that is about 80% by weight coarse aluminum powder with a median diameter of about 31.0 microns. The fuels have a cured HTPB binder. A pellet of an explosive positioned within the first hollow cylindrical layer provides ignition.
