  • High performance, low toxicity hypergolic fuel
    Patent number: 8685186
    Abstract: A group of tertiary amine azides are useful as hypergolic fuels for hypergolic bipropellant mixtures. The fuels provide higher density impulses than monomethyl hydrazine (MMH) but are less toxic and have lower vapor pressures that MMH. In addition, the fuels have shorter ignition delay times than dimethylaminoethylazide (DMAZ) and other potential reduced toxicity replacements for MMH.
    Type: Grant
    Filed: January 23, 2013
    Date of Patent: April 1, 2014
    Assignee: CFD Research Corporation

  • Filtration Apparatus and Method
    Publication number: 20090120843
    Abstract: A filtration apparatus is disclosed for the removal of metals from jet fuel at high flow rates and limited pressure drops. The filter comprises a monolayer of immobilized chelating agent on packed silica gel. The filtration apparatus is particularly useful for the removal of copper from jet fuel.
