Abstract : This new propellant is selected from a new class of propellants called solution monopropellants (SMs). SMs are liquid systems of oxygen-rich salts and hydrogen-rich solvents. SMs are energetic, relatively safe, economical, and appear attractive for use in a variety of applications. For liquid propellant guns (LPG) applications, SMs must possess three characteristics: (1) insensitivity to detonation when subjected to heavy confinement, (2) good electric arc discharge ignition characteristics with smooth and repeatable pressure traces, and (3) performance exhibiting high impetus. Of the four classes of Sm families investigated, the class derived from an oxygen-rich inorganic salt-ammonium nitrate combined with a hydrogen-rich solvent-hydrazine hydrate met all of the above criteria. Emphasis was placed on the hydronitrogen compounds such as ammonia and hydrazine and their derivatives such as hydrazine hydrate and hydroxylamine. Patents. (js)
