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 poly...
1. A method of controlling a propellant, the method comprising the steps of: a. providing an electrically controlled propellant comprising: i. a binderii. a hydroxylamine nitrate (HAN) based oxidizer;iii. a dipyridyl complexing agent; andb. cross-linking said binder with a boric acid cross-linking agent;c. igniting said propellant by applying an electrical voltage; andd. extinguishing said propellant by withdrawing said electrical voltage. 2. The method of claim 1 further comprising the step of increasing the decomposition temperature of said propellant ...
