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...
[ What is claimed is:] [1.] A composite propellant formulation comprising:an energetic binder in the range from about 10% to about 35% by weight of the composite propellant formulation, wherein the energetic binder is selected from energetically substituted oxetane polymers having a formula: [ STR 6 ] where X is --NO.sub.2, --ONO.sub.2, --N.sub.3, --NF.sub.2, or --H and Y is --NO.sub.2, --ONO.sub.2, --N.sub.3, or --NF.sub.2, energetically substituted oxirane polymers having a formula: [ STR 7 ] where X is --NO.sub.2 or --N.sub.3, and energetic nitramine ...
