Abstract

A system for improving the mechanical properties of high energy propellants utilizing solid poly(ethylene oxide) diol polymeric binders by adding minor amounts of soluble perchlorate salts to the propellant formulation.

Claims

1. In a high energy solid propellant composition consisting essentially of:

a. a solid poly (ethylene oxide) diol, binder;

b. an inorganic oxidizer; and

c. a high energy plasticizer, the improvement wherein a minor amount of a soluble perchlorate salt selected from the group consisting of lithium perchlorate and magnesium perchlorate is present in a dissolved state in said binder as a mechanical behavior improving additive.

2. A propellant composition as defined in claim 1 wherein said inorganic oxidizer is ammonium perchlorate.

3. A propellant composition as defined in claim 2 wherein said plasticizer is selected from the group consisting of (trimethylolethane) trinitrate and bis-(2-fluoro-2, 2-dinitroethyl)-formal.

4. A propellant composition as defined in claim 3 wherein said plasticizer is (trimethylolethane) trinitrate.

5. In a propellant composition as defined in claim 4 wherein said soluble perchlorate salt is lithium perchlorate.

6. In a propellant composition as defined in claim 3 wherein said plasticizer is bis-(2-fluoro-2, 2-dinitroethyl)-formal.
