A method for electrical ignition of a propellant charge provided with an electrically conductive surface coating and comprising one or more propellant components, ensuring that ignition and progressive combustion of the propellant charge takes place, wherein said propellant charge has free burning channels and at least a majority of free outer burning surfaces of the propellant charge, and inner burning surfaces of burning channels emanating therefrom, are provided with said electrically conductive surface coating prior to the ignition and wherein said method comprises:
- connecting said electrically conductive surface coating, when ignition of the propellant charge is desired, to an electrical high-voltage source, wherein said high-voltage source generates at least one high electrical pulse to said connected electrically conductive surface coating, and wherein said at least one high electrical pulse produces an instantaneous flashover ignition of the electrically conductive surface coating of the propellant charge and of all its propellant components simultaneously.
