Patent number: 10017429Abstract: An energetic material comprising an elemental fuel, an oxidizer or other element, and a carbon nanofiller or carbon fiber rods, where the carbon nanofiller or carbon fiber rods are substantially homogeneously dispersed in the energetic material. Methods of tailoring the electrostatic discharge sensitivity of an energetic material are also disclosed. Energetic materials including the elemental fuel, the oxidizer or other element, and an additive are also disclosed, as are methods of reducing ignition sensitivity of the energetic material including the additive. The additive is combined with the elemental fuel and a metal oxide to form the energetic material. The energetic material is heated at a slow rate to render inert the energetic material to ignition while the energetic material remains ignitable when heated at a fast rate.Type: GrantFiled: July 28, 2015Date of Patent: July 10, 2018Assignees: Battelle Energy Alliance, LLC, Texas Tech University SystemInventors: Michael A Daniels, Ronald J Heaps, Michelle Pantoya

Patent number: 6692655Abstract: In this method for making multi-base propellants, pelletized nitrocellulose is coated with an electrostatically insensitive liquid elastomer precursor or non-plasticizer while wetted in a non-solvent diluent, preferably in the absence of plasticizers. The non-solvent diluent is then substantially, if not completely, removed from the coated nitrocellulose. Then, the coated pelletized nitrocellulose is mixed with a plasticizer and optionally other ingredients and fillers, including energetic fuels such as nitroguanidine. The propellant formulation is then cast, and optionally cured with an acceptable curative, such as a diisocyanate or polyisocyanate. The resulting material may be visually (i.e., to the naked eye) homogeneous. Also, the coated nitrocellulose pellets present during processing have reduced sensitivity to electrostatic discharge.Type: GrantFiled: March 9, 2001Date of Patent: February 17, 2004Assignee: Alliant Techsystems Inc.Inventors: Laura J. Martins, Richard B. Cragun, Gary K. Lund, Michael V. Wells, Vincent E. Mancini

Patent number: 5468313Abstract: Castable high explosive compositions having a binder system containing plastisol grade nitrocellulose (PNC) and an energetic plasticizer are disclosed. The explosive composition also includes a solid high explosive ingredient, such as an explosive nitramine. Reactive metals, such as aluminum, magnesium or titanium, and oxidizers, such as ammonium perchlorate, ammonium nitrate, or ammonium dinitramide, are optionally included in the explosive compositions of the present invention. The disclosed explosive compositions have a typical detonation velocities above about 8000 m/s.Type: GrantFiled: November 29, 1994Date of Patent: November 21, 1995Assignee: Thiokol CorporationInventors: Ingvar A. Wallace, II, Paul C. Braithwaite, Jamie B. Neidert

Patent number: 4595430Abstract: This invention relates to improved desensitized dynamites, the improvement comprising the incorporation of a desensitizing compound selected from the class of compounds known as diesters, polyesters, triesters except those esters containing benzyl rings, and dialkyl substituted amides or combinations thereof.Type: GrantFiled: May 7, 1984Date of Patent: June 17, 1986Assignee: Atlas Powder CompanyInventor: James J. Baker

Patent number: 4507161Abstract: This invention concerns a dynamite type explosive composition which comprises at least one liquid explosive nitric ester and an emulsion composition comprising an oxygen-releasing salt phase, an organic phase and an emulsifier. The invention provides dynamite type compositions in which the amount of liquid explosive nitric ester can be significantly reduced without adversely affecting the performance and physical properties of the composition.Type: GrantFiled: February 2, 1984Date of Patent: March 26, 1985Assignee: ICI Australia LimitedInventors: Vladimir Sujansky, Sergio Tribuzio, Jolanta Paull

Patent number: 4180425Abstract: A new gelatine explosive composition is disclosed comprising mixtures of nitric esters, ortho-nitro-toluene, blasting soluble nitrocotton, oxidizing salts, fuels and at least one dispersing agent. Said gelatine explosive composition is markedly reduced in the quantities of liquid nitric esters and blasting soluble nitrocotton content.Type: GrantFiled: July 21, 1978Date of Patent: December 25, 1979Assignee: Indian Explosives LimitedInventors: Bidhan C. Ghosh, Gopal M. Chopra, Soumendra N. Sen
