摘要： A sodium-azide-free gas-generating composition includes an oxidizable inorganic fuel, such as a metal, and an oxidizing agent containing oxygen and a metal. The fuel and the oxidizing agent are selected such that water vapor is produced upon reaction between the inorganic fuel and the oxidizing agent. Although a number of inorganic fuels can be employed, a suitable fuel can be a transition metal, another element such as silicon, boron, aluminum, magnesium, and intermetallic compound, hydrides of these metals and mixtures thereof. Suitable oxidizing agents are selected from basic metal carbonates and basic metal nitrates. The fuel and oxidizing agent are selected such that substantially nontoxic gases are produced such as mixtures of water vapor and either carbon dioxide or nitrogen.

摘要： Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite amine, metal nitrate amine, and metal perchlorate amine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices such as automobile air bags.

摘要： Methods and materials for modifying rocket motors to render them safer are disclosed. The invention is primarily related to placing within the bore of a rocket motor a sufficient quantity of a material mitigant such that if the rocket motor receives an unintended impact, the material mitigates the effects of the impact, and prevents ignition or explosion of the propellant. The material mitigant may take a number of forms; however, polymer foams and fibers of various types have been found to work well. It is presently preferred that the material mitigants have a density of not less than approximately 0.04 grams/cc. Examples of such materials include polyurethane foam, polystyrene, and Kevlar® fibers. It is also preferred that the material mitigant not be reactive with the propellant in the rocket motor. While the material mitigant is configured such that it absorbs fragments or energy of propellant dislodged by the impact, at the same time it does not interfere with the normal ignition and operation of the rocket motor.
