Abstract : The fuel systems in liquid fueled air-breathing missiles utilize bladders which must be pressurized to expel the fuel. Gas generators used to pressurize these bladders must meet certain specifications not normally required of gas generators. They must produce gases that are lower in temperature than those ordinarily produced by gas generators. In addition, they must produce these gases more rapidly than ordinary gas generators and, therefore, require faster burning peopellants. Further, they must maintain constant pressure for approximately 90 seconds and thus must burn at a constant burning rate. Still further, the gases produced must be substantially free of solids. A propellant formulation comprising a polysulfide binder having the formula-(SCH2CH2OCH2OCH2CH2S) wherein n is a positive integer of sufficient magnitude to render the binder an elastomeric solid, ammonium perchlorate, ammonium oxalate and iron oxide. The formulation has properties which render it useful for generating gas to pressurize the fuel systems in air-breathing missiles.
