Abstract
A method for contactless inductive transmission of programming data to a programmable time fuse included in a shell for a single shot, semi-automatic, or fully automatic shell firing barrel weapon. While the shell is situated in a cartridge chamber of a barrel of the weapon, data is transmitted to the programmable time fuse from a programming device of the weapon via a transmitting coil arranged around the cartridge chamber of the barrel to a receiving coil arranged in the shell. At least a part of the barrel lying between the coils is replaced by a non-magnetic material and designed so that it does not form an electrically conductive short circuited layer that would prevent transmission between the coils.
