초록

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 pr...
