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).
Claims7
A method of controlling a propellant, the method comprising the steps of:
- a. providing an electrically controlled propellant comprising:
- i. a binder
- ii. a hydroxylamine nitrate (HAN) based oxidizer;
- iii. a dipyridyl complexing agent;
- and
- b. cross-linking said binder with a boric acid cross-linking agent;
- c. igniting said propellant by applying an electrical voltage;
- and
- d. extinguishing said propellant by withdrawing said electrical voltage.
