Composite propellant formulations are disclosed having a dinitramide salt oxidizer, such as ammonium dinitramide, an energetic binder, such as energetically substituted oxetane and oxirane polymers, a reactive metal, such as aluminum, and other typical propellant ingredients such as curatives and stabilizers. Propellant formulations useful for minimum smoke or reduced smoke applications, preferably include little or no reactive metal. The disclosed propellant formulations are able to combust the reactive metal efficiently, possess high burn rates, and produce little or no HCl exhaust gases.

Propellant formulations based on dinitramide salts and energetic binders

The use of 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazatetrocyclo[5.5.0.0.sup.5,9 0.sup.3,11 ]-dodecane as the major explosive ingredient in compositions useful in high performance, low sensitivity explosive applications is disclosed.

Insensitive high performance explosive compositions

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.
