An oxidizer package for a propellant system for a motor in which the oxidizer is separated from fuel grain, the oxidizer package comprising oxidizer material and an ignition system therefor in a wrapping or sealing material. A hybrid rocket comprising oxidizer material and fuel grain, the oxidizer material being separated from the fuel grain and being in the form of a single package or plurality of packages of oxidizer material and an ignition system therefor, said packages generally conforming to the shape of the rocket. A grid of a pyrotechnic material. A propulsion system for a hybrid rocket comprising oxidizer material in a matrix, mesh, wool, foamed metal or wires of structural or pyrotechnic material.

1. An oxidizer package for a propellant system for a motor in a rocket, the oxidizer package comprising: an oxidizer material disposed in a matrix, the oxidizer material being contained in ampoules within the matrix; and an ignition system therefor, wherein the matrix comprises a material selected from the group consisting of an ancillary compound, a mixture of an oxidizer and an ancillary compound, and a pyrotechnic material, the ancillary compound undergoing exothermic decomposition substantially without consumption of oxygen from the oxidizer material. 2. The package of claim 1 in which the oxidizer material is a liquid, a solid or a semi-solid material. 3. The package of claim 1 in which the ampoules further contain carriers or perfonrmance enhancing compounds selected from the group consisting of a fluoropolymer, a fluoroelastomer, an energetic polymer, a non-energetic polymer, an energetic metal, a crystalline explosive, polymerized peroxide, a metal hydride and a double-base propellant. 4. The package of claim 1 in which the ampoules are in the form of at least one of spheres, capsules, pellets, rods and tubes. 5. The package of claim 1 in which the ampoules comprise a shell formed from at least one of coated aluminum, pyroalloying metal foil, a laminate or sheet of aluminum, a laminate or sheet of magnesium, an energetic polymer, a non-energetic polymer, nitrocellulose and a double-base propellant. 6. The package of claim 4 in which the ampoules comprise a shell formed from at least one of coated aluminum, pyroalloying metal foil, a laminate or sheet of aluminum, a laminate or sheet of magnesium, an energetic polymer, a non-energetic polymer, nitrocellulose and a double-base propellant. 7. The package of claim 5 in which the coated aluminum is selected from the group consisting of polymer-coated aluminum, aluminum coated with a mixture of polymer and magnesium, and aluminum coated with a fluoroelastomer and magnesium. 8. The package of claim 6 in which the coated aluminum is selected from the group consisting of polymer-coated aluminum, aluminum coated with a mixture of polymer and magnesium, and aluminum coated with a fluoroelastomer and magnesium. 9. The package of claim 1 in which the packages are stackable in a column. 10. The package of claim 1 in which the matrix is the ancillary compound. 11. The package of claim 10 in which the ancillary compound is selected from the group consisting of HTPB, PBAN, epoxy, thermoplastic polymer, GAP, BAMO/AMMO and BAMO/NMMO. 12. The package of claim 1 in which the matrix is polyethylene/vinyl acetate (EVA), optionally cross-linked. 13. The package of claim 1 in which the oxidizer is selected from ammonium perthlorate, ammonium nitrate, ammonium dinitramide, hydroxylammonium nitrate, hydroxylammonium perchlorate, hydrazinium nitroformate, nitronium perchlorate, nitric acid, hydrogen peroxide and nitrocellulose/nitroglycerine. 14. The package of claim 1 in which the matrix comprises 90-94% oxidizer, 2.5 -4.5% ancillary compounds, 0.5-1.0% burn rate modifiers, 0.5-1.0% energetic metals, 0.2-0.5% process-modifiers and 0.2-0.4% curative agents. 15. The package of claim 1 in which there is more than one initiator. 16. The package of claim 15 in which there are 2 to 4 initiators. 17. The package of claim 4 in which the ampoules comprise a shell formed from the pyrotechnic material.
