Composite propellant formulations are disclosed having a dinitramide salt oxidizer, such as ammonium dinitramide, an energetic binder, such as poly(glycidyl nitrate), a reactive metal, such as aluminum, and other typical propellant ingredients such as curatives and stabilizers. The disclosed propellant formulations are able to combust aluminum efficiently, possess high burn rates, and produce little or no HCl exhaust gases.
A composite propellant formulation which does not contain chlorine comprising: poly(glycidyl nitrate) binder having a concentration in the propellant formulation in the range from about 10% to about 35% by weight; a dinitramide salt oxidizer in the range from about 50% to about 70% by weight; a reactive metal selected from aluminum, magnesium aluminum-magnesium alloys, and boron, said reactive metal having a concentration in the propellant formulation in the range from about 2% to about 25% by weight; and a polyfunctional curative.
