A method for direction limitation of a firing system. A first calculating unit controls the firing system and knows direction limitation positions. An elevation of the firing system and a traverse of the firing system are measured. A position of the firing system is calculated in the first calculating unit based on the elevation and traverse. The position of the firing system is calculated in a second calculating unit based on the elevation and traverse. The calculated positions of the firing system are compared with direction limitation positions. It is decided whether the firing system is positioned outside the direction limitation positions. Also, a direction limitation system for a firing system.

Method for direction limitation and system for direction limitation

An ammunition management system for firing mixed ammunition in an automatic cannon. The ammunition management system includes a rotatable ammunition magazine including ammunition shot, a breech casing and an ammunition feed device for feeding of ammunition shot between the ammunition magazine and the breech casing. A drive device drives the ammunition magazine via a chain drive mechanism disposed in the ammunition magazine. A decoupling device engages and disengages the ammunition magazine with respect to the ammunition feed device, so that ammunition can be moved between different positions in the ammunition magazine, via an alternating process including: feeding of ammunition from the ammunition magazine to the ammunition feed device, disengagement of the ammunition magazine, rotation of the ammunition magazine, engagement of the ammunition magazine, and feedback of ammunition from the ammunition feed device to the ammunition magazine. A method for sorting ammunition in a ammunition magazine.
