    摘要: A low cost infrared flare composition which uses a high molecular weight fluorinated resin, a low molecular weight fluorinated resin, a polymerizing solvent, and an initiator to form a binder which is combined with a reducing agent to yield a composition readily processable into various grain shapes and varying degrees of hardness thereby providing more consistent burning rates.

    摘要: A solid non-azide composition for generating non-toxic nitrogen gas intended for use in the deployment of inflatable safety crash bags for driver and passenger protection in vehicles consists essentially of a non-hydrogen containing tetrazole compound and a non-oxygen containing oxidizer, examples of the tetrazole being di-alkali metal or mono-alkaline earth metal salts of 5,5'-bitetrazole, and examples of the oxidizer being sulfur, molybdenum disulfide, chromium trichloride and iron trifluoride.

    摘要: Ammonium perchlorate particles having strongly adherent wettable coatings are made by treating the particles with stong amines that displace ammonia to form amine perchlorates at the particle surfaces. Silanylamines are preferred since after amination of the perchlorate the silane groups can be hydrolyzed to siloxanes having good wettability by liquid polymeric propellant binders. The coated perchlorate can be used to produce solid propellants having improved mechanical properties and burning characteristics.

    摘要: Internally plasticized elastomeric binders for projectile propellants are cured polyethers containing THF, CYMMO plus BMEMO, BEEMO and/or OMMO mer units. The polyethers are fluid at room temperature and are miscible with nitrate ester plasticizers. Propellant binders prepared from these polyethers are curable, have low T.sub.g 's, good mechanical properties, and I.sub.sp 's comparable to PEG-based binders.

    摘要: Improved igniter compositions for rocket motors are provided which, when cured, are non-volatile and are capable of igniting under vacuum conditions and burning steadily at reduced pressures. Said igniter compositions comprise:(a) about 11% to about 13% hydroxyl terminated polybutadiene binder prepolymer;(b) about 0.7% to about 2.0% polyfunctional isocyanate curing agent for said binder prepolymer;(c) about 2.0% to about 20% metallic powder fuel;(d) about 20% to about 40% large particle size ammonium perchlorate;(e) about 30% to about 50% small particle size ammonium perchlorate;(f) about 0.05% to about 5.0% non-volatile burning rate catalyst;(g) about 0.05% to about 0.50% bonding agent capable of wetting the solids in the composition by said binder prepolymer and of chemically coupling with said ammonium perchlorate; and(h) about 0.01% to about 0.20% ammonia scavenger wherein all percentages are by weight based on the total weight of the compositions.
