Inhibited Red Fuming Nitric Acid (IRFNA) type IIIB and monomethyl hydrazine (MMH) ignite when contacted with each other because of a hypergolic chemical reaction and are the preferred oxidizer and fuel for bipropellant rocket propulsion systems. These propellants can deliver a specific impulse of 284 lbf sec/Ibm and density impulse of 13.36 lbf sec/cubic inch when the engine operating pressure is 2000 psi. Special precautions must be used when handling because of its toxic properties. A fuel gel propellant fuel that would be a suitable replacement for MM...
[ I claim:] [1.] A hypergolic liquid or gel fuel propulsion system comprising:(i) a tertiary amine azide selected from the group of tertiary amine azides consisting of dimethylaminoethylazide, and pyrollidinylethylazide; and,(ii) an oxidizer selected from the group of oxidizers consisting of inhibited red fuming nitric acid, nitrogen tetroxide, hydrogen peroxide, hydroxyl ammonium nitrate, and liquid oxygen.
