Abstract: The invention disclosed herein relates to an explosive capable of enhanced combustion efficiently capable of sustaining a high pressure over a period of time in a confined environment, such as an air tight room or a cave, where oxygen may be in limited supply. An embodiment of the present invention is a metal composite that combines a binder, a reactive metal and an oxidizer. In another embodiment, a plasticizer and a catalyst are added. In another embodiment of the present invention, a solid fuel-air explosive (SFAE) having an annular construction is used. In a typical annular construction, a cylindrical shell of SFAE surrounds the cylindrically shaped high explosive. The SFAE includes at least one of reactive metal and metal composite. In addition, the metal composite is formed from at least one reactive metal, at least one binder and an oxidizer.

Abstract: This invention relates to energetic compositions, which offer increased performance in conjunction with a total absence of halogen based oxidizers to eliminate exhaust products, such as hydrogen chloride. The oxidizers of choice are various combinations neat ammonium dinitramide, ammonium dinitramide prills and CL-20, because these oxidizers do not produce halogen containing exhaust products, such as the HCl gas of ammonium perchlorate. The exhaust these novel propellants consist mostly of CO2, H2O, N2, and small amounts of CO. These exhaust species are friendlier and much less hazardous to the environment than those emitted by conventional AP-based propellants. The plasticizers are selected from energetic plasticizers that do not contain halogens, but maintain other desirable properties.
