摘要:
A gas generator 10 includes an auto-ignition/booster composition 212 that contains a metal chlorate such as potassium chlorate as an oxidizer, a carboxylic acid such as DL-tartaric acid as a primary fuel, a secondary oxidizer such as strontium nitrate, and if desired, a secondary fuel such as 5-aminotetrazole. The auto-ignition/booster composition 212 and a separate provision of ammonium nitrate or phase stabilized ammonium nitrate 228 are provided within a single combustion/decomposition chamber 222 for the production of gas, upon actuation of the gas generator 10. Vehicle occupant protection systems 180, containing the gas generator 10, are also provided.
摘要:
Oxidizing compounds are provided which have improved thermal stability and which are particularly useful in explosive and propellant compositions. Such oxidizers are produced by making solid solutions of the oxidizer with at least one other compound. The solid solutions of particular interest for the purpose of this invention are ammonium perchlorate (NH4CIO4) and potassium perchlorate (KClO4), or ammonium perchlorate and ammonium nitrate (NH4NO3).

摘要:
Sulfur-free and carbon-free, white propellant compositions for use as a blackpowder substitute in firearms, munitions, and pyrotechnics to form combustion byproducts that are water soluble and are free of corrosive sulfur compounds and black carbon residues. Formulations include a fuel agent selected from the group consisting of sodium benzoate, lactose, sodium salicylate, sodium m-nitrobenzoate, and mixtures thereof. The fuel agent is combined with dextrin, potassium nitrate, potassium perchlorate, and tricalcium phosphate. Dicyanodiamide may be incorporated in the formulation as a burn rate modifier.
摘要:
A low temperature and low humidity process of making a pyrotechnic composition useful as gunpowder, a propellant or an explosive. The composition comprises an organic acid such as ascorbic or erythorbic acid, a nitrate salt oxidizer, and about 6-15% of potassium perchlorate, and has reduced residue upon use.
摘要:
The invention relates generally to a small model rocket motor. The motor includes a plastic composite propellant, and plastic ablative nozzle, and provides means for producing thrust, a time delay, and a charge to activate external devices of desirable design.
摘要:
The present invention relates to a gas generant composition that has a high ignitability and combustibility and is capable of quickly responding to an electrical signal for starting combustion, and particularly to a gas generant composition comprising a nitrogen-containing organic compound as a fuel component (A), a metal nitrate and/or a basic metal nitrate (B-1) and a perchlorate (B-2) having a 50 percent particle diameter from 1 to 50 μm as an oxidant component (B), the content of the perchlorate (B-2) in the total mass of the oxidant component (B) is 5 mass percent or more and less than 35 mass percent.
摘要:
The solvent-free gas generant composition of this invention, comprising an oxidizer and a thermosettable resin, cures in about an hour or less at room temperature and within 5 minutes at 135.degree. F. Void-free and crack-free gas generant grains are formed and cured in an extrusion process in which the temperature may be from about room temperature to about 200.degree. F. The thermosettable resin is at least one of the group consisting of an acrylate-terminated polybutadiene, a hydroxy-terminated polybutadiene/diisocyanate reaction product, an ester of a polybutadiene polycarboxylic acid and an epoxy modified polybutadiene and/or a hydroxyl-terminated polybutadiene, and a styrene/polyester copolymer.
