Abstract
Liquid oxygen systems are currently used in all high specific impulse, high thrust space propulsion systems. Although more energetic oxidizers have been demonstrated to exhibit superior performance, they have not been used because of their reactivity with materials and/or their hazards. Mixtures of powerful solid oxidizers with solid oxygen have been found to have greatly reduced reactivity and greatly increased stability. Solid cryogenic oxidizers are one part of what the American Space Exploration Initiative has recently recognized as the nationally critical technology of cryogenics. This proposal describes a solid oxidizer condensed directly into a solid, extruded, formed into pellets, and injected at high pressures. A constant injection rate that minimizes the possibility of combustion instabilities is achieved through mass-dependent pellet spacing. The work described in this proposal provides an example of technology transfer from a well developed specialized field (pellet fueling of fusion plasmas) to a promising new technology. The proposed storage, feed, and digital injection system is expected to be able to satisfy the rigorous requirements for the use of a solid oxidizer propellant.
