Abstract
An electrically operated propellant is configured to ignite and extinguish over a range of pressures. In examples, the electrically operated propellant is included in a gas generation system having a combustion chamber and at least two electrodes coupled with the propellant. The electrically operated propellant is configured to ignite at an ignition condition and extinguish under an extinguishing condition. In the ignition condition an electrical input is applied across the electrodes to ignite the electrically operated propellant. In the extinguishing condition the electrical input is interrupted while the pressure within the combustion chamber is greater than 200 psi, and the ignited electrically operated propellant extinguishes.
