Abstract
The invention relates to a propellant charge comprising a compact propellant and a method for electrically initiating and controlling the burning of such a propellant charge. Electrothermal energy is supplied to the propellant charge by feeding electric current over electrically conductive surfaces (6, 7, 19) in the propellant, and that said supply is made to different parts or zones (15) of the propellant charge at different points of time during the burning. The invention specifically relates to a projectile propellant charge having a first end (9) facing the projectile (4) and a second end (10) facing the back (3) of the weapon. The electrothermal energy is then supplied to the propellant charge, beginning in the first end thereof and then successively to the second end thereof by feeding the current at each point of time over an axially restricted part (15) of the propellant charge.
