  • Propellant system for solid fuel rocket
    Patent number: 7022196
    Abstract: An oxidizer package for use in a solid fuel propellant system. The oxidizer package comprises a solid oxidizer in the form of discrete pellets of predetermined geometric shape. The pellets are arranged in an array with spaces amongst the pellets. A holder is provided for maintaining the pellets in the array for receipt of a binder introduced to spaces amongst the array of pellets. Preferred propellants include hydrazinium nitroformate and nitronium perchlorate. This arrangement for the pellets can achieve loadings as high as 85% by weight for the pellets.
    Type: Grant

  • Oxidizer package for propellant system for rockets
    Publication number: 20040244890
    Abstract: 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.
