Abstract: Hypergolic liquid or gel fuel mixtures utilized in bipropellant propulsion systems are disclosed as replacements for fuels containing toxic monomethylhydrazine. The fuel mixtures include one or more amine azides mixed with one or more tertiary diamine, tri-amine or tetra-amine compounds. The fuel mixtures include N,N,N?,N?-tetramethylethylenediamine (TMEDA) mixed with 2-N,N-dimethylaminoethylazide (DMAZ), TMEDA mixed with tris(2-azidoethyl)amine (TAEA), and TMEDA mixed with one or more cyclic amine azides. Each hypergolic fuel mixture provides a reduced ignition delay for combining with an oxidant in fuel propellant systems. The fuel mixtures have advantages in reduced ignition delay times compared to ignition delay times for each unmixed component, providing a synergistic effect which was not predictable from review of each component's composition.

Abstract: A pyrophoric material comprises a pyrophoric metal coated onto a wire mesh substrate. Iron and nickel are the preferred metals and a steel wire mesh is suitable. A process for making the pyrophoric material involves spraying an alloy of iron and/or nickel with aluminium onto a mesh using a high velocity oxy-fuel (HVOF) process following by leaching out at least a proportion of the aluminium by treatment with an alkaline solution. The product has application as a supported catalyst or as either an ignition medium or as a flare material in military countermeasures in which applications it is capable of burning at a high temperature.

Abstract: A method for preparing a gelled liquid propane (GLP) composition comprises the introduction of liquid propane into an evacuated mixing vessel containing a gellant and mixing the liquid propane with the gellant. A bi-propellant system comprising GLP is particularly well-suited for outer planet missions greater than 3 AU from the sun and also functions in earth and near earth environments. Additives such as powders of boron, carbon, lithium, and/or aluminum can be added improve performance or enhance hypergolicity. The gelling agent can be silicon dioxide, clay, carbon, or organic or inorganic polymers. The bi-propellant system may be, but need not be, hypergolic.

Abstract: Techniques and processes that combine particulate coating processes with particulate handling steps resulting in the formation of free-flowing particulates for introduction into energetic product vessels to affect an in-situ, net-shape manufactured product. The processes involve selecting suitably sized materials, processing such materials such that they are surface-coated and/or locally “structured” particulates, and pouring, preferably “dry” pouring, these processed materials into an energetic product vessel and infusing the filled vessel with a polymerizable and surface-compatible monomer or oligomer which flows into the unoccupied volume, followed by polymerization of the monomer, which then becomes the binder giving mechanical integrity to the final, net-shape energetic composition.
