Liquid oxidizer comprising an aqueous solution of hydroxyl ammonium nitrate nd a nitrate salt that is ammonium nitrate or hydrazine mononitrate.

Oxidizing agent

A liquid monopropellant composition comprising the water solution of an hydroxylammonium nitrate and a compatible water soluble or water dispersible fuel.

Monopropellant aqueous hydroxyl ammonium nitrate/fuel

A pyrotechnic composition, suitable for metal cutting, comprises an oxidi selected from the class consisting of calcium sulfate hemihydrate, anhydrous calcium sulfate, magnesium monohydrate, anhydrous magnesium sulfate, anhydrous strontium sulfate, and mixtures thereof; a metal fuel, a halopolymeric binder; and sulfur.

Metal-cutting pyrotechnic composition

A liquid monopropellant composition comprising the water solution of hydrlammonium perchlorate and a compatible water soluble or water dispersible fuel.

Monopropellant composition

At least one combustion modifier is incorporated in liquid propellants by ssolving the modifier in at least one solvent such as alkoxypolyethylene glycol ether or a bis(alkoxypolyethylene glycol) formal to form a solution and mixing the resulting solution with the energetic component of the liquid propellant. Similar solutions of combustion modifier are also suitable for use as casting liquids in cast double-base propellants.

Liquid monopropellants containing dissolved combustion modifiers

Monomethylhydrazine and dimethylhydrazine are prepared in a multi-step prss which comprises the steps of reacting chlorine and ammonia to form gaseous chloramine, introducing the chloramine into the lower reaction layer of a liquid two-phase caustic-amine or caustic/ammonia system, reacting the chloramine with the available ammonia or the available amine, and then transferring the forming hydrazine from the lower reaction layer to the upper storage layer of the two-phase system.
