Abstract
The invention relates to a method of, in the electrical ignition of a propellent charge () provided with an electrically conductive surface coating () and comprising one or more propellant components (), ensuring that ignition and progressive combustion of the propellent charge take place. The method is characterized in that said electrically conductive surface coating, when ignition of the propellent charge is desired, is connected to an electrical high-voltage source (), in that said high-voltage source is made to generate at least one high electrical pulse to said connected electrically conductive surface coating, and in that said at least one high electrical pulse produces an instantaneous flashover ignition of the electrically conductive surface coating of the propellent charge and of all its propellant components, simultaneously. The invention also relates to a propellent charge and to an ammunition shot comprising the propellent charge.
