The invention relates to a device and a method for controlling in an electrothermal-chemical manner the burning of a propellant charge, especially during firing of a barrel gun. Burning is controlled by using electric energy to conduct a current through the burning zone. In prior-art devices and methods, use is made of a capacitor bank which gives one or more current pulses as a source for the electric energy. This means that the current is supplied by a charged capacitor which is discharged. To achieve high ohmic heating, the pulse asssembly must supply a high current. This is disadvantageous since there is a risk that the high current causes an undesirable arc discharge (electric charge) between the electrodes. The method and the device according to the invention control the burning of a propellant charge (3) by conducting a current (I) through the burning zone (4) of the propellant charge, preferably through the flame front (5), where the current (I) is generated by an applied alternating voltage. |
