Abstract: A process of crystallizing CL-20 is disclosed. In the process, a wet CL-20 solvent/CL-20 solution is dried by azeotropic distillation of a CL-20 solvent/water azeotrope. Removal of water from the CL-20 solution permits crystallization of high density CL-20. A low density, CL-20 non-solvent is added to the resulting dry CL-20 solvent/CL-20 solution to cause precipitation of epsilon -polymorph CL-20. The CL-20 crystals are separated from the non-solvent and the solvent by adding sufficient water to displace the non-solvent and the solvent from the surface of the CL-20 crystals. In this fashion, the epsilon -polymorph CL-20 is made wet for later handling, packaging, and shipping.

Abstract: Gas generating compositions for inflating automobile air bags and similar devices are provided. The gas generating compositions use dicyanamide salts as a primary fuel. The dicyanamide salts are selected from the group consisting of alkali metal, alkaline earth metal, metalloidal, and transition metal dicyanamides, and complexes thereof. If desired other fuels, in addition to the dicyanamide salts may be incorporated into the compositions. Such fuels may include organic fuels, preferably with high nitrogen contents or nitrides. The compositions also include oxidizer-effective quantities of oxidizers. Typically, such oxidizers will be selected from the group consisting of metal nitrates, metal perchlorates, metal chlorates, and transition metal oxides. In some cases it may be desired to include a second oxidizer in addition to those listed above. Examples of such additional oxidizers will include transition metal oxides such as Fe2O3, MnO2, and CuO, and Co2O3.

Abstract: 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, an intermetallic compound, hydrides of these metals and mixtures thereof. The oxidizing agent comprises a metal hydroxide, a metal hydrous oxide, a metal oxide hydrate, a metal oxide hydroxide, or mixtures thereof. The fuel and oxidizing agent are selected such that essentially no gases other than water vapor are produced.

Abstract: 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 Kevlar3 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.

Abstract: Compositions are provided which, when burned, produce significant levels of infrared radiation, but only limited levels of visible radiation. The basic components of the compositions include a binder, an oxidizer, and a fuel, where the binder also acts as the fuel. Preferred oxidizers include those compounds which produce large quantities of infrared radiation when the flare composition is burned. Such oxidizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these compounds. Selection of the binder is important in order to provide the composition with the desirable characteristics identified above. The binder of the present invention does not produce significant soot. At the same time, the binder serves to form a composition which is processible, avoids chunking, and is compatible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continuous carbon atoms) are preferred. Examples of such polymers include polyesters, polyethers, polyamides and polyamines.

Abstract: The present invention concerns a method for making energetic oxidizer salts and solutions thereof, and in particular relates to processes for making aqueous solutions of hydroxylammonium nitrate in high purity suitable for use in making liquid gun propellants. The present alcohol-free process yields high purity alcohol-free hydroxylammonium nitrate by neutralizing an aqueous nitric acid solution (20-70 % wt./wt.) with an alcohol-free aqueous hydroxylamine solution at temeperatures ranging from above -50 C to above ambient to produce the desired alcohol-free aqueous hydroxylammonium nitrate solution in a usable concentration and in high purity. The process is economical, environmentally acceptable, and facile.
