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.
