Patent number: 6849247Abstract: A gas generating process, which is for the continuous production of energy and hydrogen for rocket and other propulsion and is also for the continuous production of hydrogen, utilizes the reaction of metallic materials, particularly aluminum, with organic materials, particularly hydrocarbons provided as jet fuel, and with water or an oxidizer which is predominantly water. In comparison with related reactions, the reaction produces hot gases containing more hydrogen and the products have a lower temperature for the same specific impulse. The process incorporates organic liquids with metallic powders to produce desirable, lower molecular weight exhaust gas products; and the increased hydrogen is desirable for use with a fuel cell and in connection with propulsion of a super-cavitating underwater device. The process is advantageous in that a metal, in powdered form, and a hydrocarbon liquid may be provided together as a slurry or gel for effective metering.Type: GrantFiled: July 10, 2002Date of Patent: February 1, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Kerry L. Wagaman, Douglas J Elstrodt

Patent number: 6843868Abstract: A non-/low-toxic, non-hypergolic, propellant formulation generally comprising metal nanoparticles, such as boron, aluminum, or carbon, and one or more fluoro-polymers mixed in in particulate form. The present invention takes advantage of the increased surface area provided by nano-sized metallic particles to enhance the metal's combustion efficiency, or ignitability. The inclusion of fluoro-polymers also aids in increasing the combustion efficiency of the metallic nanoparticles due to the presence of halogenic oxidizers. The thermal degradation of a halogenated fluoro-polymer additive in the propellant combustion zone serves to release halogens, thereby improving the combustion of the metallic nanoparticles and increasing the propulsion system's energy output. The present invention's formulation is safe to store and handle, environmentally-friendly, and may be economically manufactured to provide for widespread, cost-effective use.Type: GrantFiled: October 23, 2003Date of Patent: January 18, 2005Assignee: The United States of America as represented by the Secretary of the NavyInventors: Christopher J. Fawls, Joel P. Fields, Kerry L. Wagaman

Patent number: 6652682Abstract: The present invention is a propellant composition comprising from about 2 percent to about 46 percent, by weight, boron particles having a diameter of less than about 500 nanometers. Liquid or gel embodiments of the invention may also include adding the boron particles to a liquid fuel in order to form a liquid fuel system. Examples of such liquid fuels include ethyl ammonium nitrate (EAN), triethyl amine nitrate (TEAN), Cyclotetramethylenetetranitramine (HMX), trinitrotoluene (TNT), jet fuel formula (JP-10), kerosene, RJ-4, or other hydrocarbon based fuels. These liquid fuel systems can be part of bipropellants wherein the liquid fuel system is stored separately from an oxidizing agent and the two are mixed during operation. Examples of oxidizing agents may include nitrogen tetroxide, oxygen, hydrogen peroxide, hydroxyl ammonium perchlorate (HAP), hydoxyl ammonium nitrate (HAN), ammonium perchlorate, ammonium nitrate, ammonium dinitramide (ADN), or a combination of said chemicals.Type: GrantFiled: October 17, 2001Date of Patent: November 25, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventors: Christopher J.

Patent number: 6258983Abstract: The present invention comprises a process of producing HAN by slowly adding nitric acid to an alcoholic solution of hydroxylamine. This forms a precipitate of solid HAN. However, if more nitric acid is added, the precipitate dissolves before the stoichiometric amount of acid has been added. Therefore, sufficient nitric acid is added to form a maximum amount of solid HAN precipitate. The solid HAN is then isolated by conventional means such as filtration or centrifugation, possibly preceded by chilling this solution. The excess alcoholic solution of unreacted hydroxylamine may be recycled and used as starting material in the process.Type: GrantFiled: October 12, 2000Date of Patent: July 10, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventor: Kerry L.
