    • This invention relates to energetic compositions, which offer increased performance in conjunction with a total absence of hydrogen chloride in the combustion products. The formulation avoid the use of halogen based oxidizers to prevent the formation of halogen based byproducts. The formulations disclosed herein use ammonium dinitramide as a primary oxidizer, which is a more energetic molecule than ammonium perchlorate. The solid propellant formulations disclosed herein comprise about 5.0 to about 10.0 weight % of at least one energetic binder; about 20.0 to about 35.0 weight % of an energetic plasticizer; about 25.0 to about 45.0 weight % of ammonium dinitramide as a primary oxidizer; about 0.0 to about 20.0 weight % of particulate aluminum having a particle size of about 1 &mgr;m to about 60 &mgr;m; and about 0.0 to about 20.0 weight % of ultrafine aluminum having a particle size of less than 1 &mgr;m. In addition to the ingredients in this basic formulation will be cure catalysts, curatives, crosslinkers, burn rate catalysts and modifiers, thermal and aging stabilizers other such ingredients commonly utilized in solid propellant formulations.
    • 本发明涉及能量组合物,其与燃烧产物中完全不存在氯化氢一起提供了更高的性能。 该制剂避免使用卤素基氧化剂以防止形成基于卤素的副产物。 本文公开的制剂使用二硝基铵作为主要氧化剂,其是高于高氯酸铵的分子。 本文公开的固体推进剂制剂包含约5.0至约10.0重量%的至少一种能量粘合剂; 约20.0至约35.0重量%的能量增塑剂; 约25.0至约45.0重量%的二硝基铵铵作为主要氧化剂; 约0.0至约20.0重量%的粒度为约1μm至约60μm的颗粒状铝; 和约0.0至约20.0重量%的粒度小于1μm的超细铝。 除了这种基本配方中的成分之外,固化催化剂,固化剂,交联剂,燃烧速率催化剂和改性剂,热稳定剂和老化稳定剂,其它这些成分通常用于固体推进剂配方中。
