1. A gas generation system, comprising:

  • a combustion chamber;

    an electrically operated propellant within the combustion chamber; and

    a pair of electrodes configured for coupling with an electrical power source, said electrical power source configured to apply an electrical input across the electrodes creating an ignition condition in which (a) a current density (J) through the propellant between the pair of electrodes on an ignition surface exhibits a decreasing gradient along an axis normal to the ignition surface, (b) a contour of the ignition surface approximately matches a contour of current lines between the electrodes to within 5% such that current density J is approximately constant across the ignition surface to within 5% and (c) the current density J at the ignition surface exceeds an ignition threshold as approximately all of ignition surface burns and regresses along the axis.
