Solid electrically controlled propellants
The present application discloses a variety of improvements that enhance at least one of the mechanical, chemical/energetic, ballistic, or adhesive properties, of a class of ECPs, regardless of whether said ECPs are in solid phase or gels, singly or in combinations thereof.
1. An improved electrically controlled propellant wherein:
a. The electrically controlled propellant comprises boric acid; and
b. tetrazole without functional group substitutions.
2. The improved electrically controlled propellant of claim 1 wherein:
a. said boric acid is alters the interim viscosity of the electrically controlled propellant.
3. The improved electrically controlled propellant of claim 2 wherein:
a. said electrically controlled propellant comprises approximately 0.01 to 5% by weight boric acid.
4. The improved electrically controlled propellant of claim 1 wherein:
a. said electrically controlled propellant comprises approximately 0.01 to 5% by weight boric acid.
5. The improved electrically controlled propellant of claim 1 wherein:
a. said electrically controlled propellant comprises more than 0.001% by weight boric acid.
6. The improved electrically controlled propellant of claim 1 wherein:
a. said boric acid improves cross-linking and increases the mechanical strength of the electrically controlled propellant.
7. An improved electrically controlled propellant wherein:
a. the electrically controlled propellant comprises boric acid; and
b. at least one nitrogen heterocycle in the class of azoles: imidazole, pyrazole, 1,2,3-triazole, without various functional group substitutions on the class structures.
