Abstract
The present invention is an electrically controlled propellant comprising a binder, an oxidizer, and a cross-linking agent. The boric acid (the cross-linking agent) has been found to function as a cross-linking agent for the high molecular binder used to make the propellant, thereby improving the composition's ability to withstand combustion without melting. The present invention also may include 5-aminotetrazole (5-ATZ) as a stability-enhancing additive. The binder of the present invention may include polyvinylalcohol (PVA) and/or the co-polymer of polyvinylalcohol/polyvinylamine nitrate (PVA/PVAN).
