The present invention relates to an automatic charge magazine (1) for storage and handling of propellent powder charges of the modular charges and/or powder bag charges type, also termed increment charges (4), for projectiles, for example shells, which are arranged in a fireable manner, together with the increment charges (4), in an artillery gun, preferably of the vehicle-mounted artillery gun type, wherein the charge magazine (1) comprises a plurality of charge containers (5, 5′, 5″) arranged in a drivable revolving track, which charge containers (5, 5′, 5″) are arranged to assume feed-in and feed-out positions (2, 11) for the feed-in and feed-out of at least one increment charge (4) to and from the charge containers (5, 5′, 5″). The invention can principally be deemed to be characterized in that the charge magazine (1) also comprises at least one ejection member (15, 31, 32, 33, 34), which ejection member, in response to control signals (i2) from the said control unit (22), ejects one or more increment charges (4) from the respective charge container (5, 5′, 5″)/applied in the feed-out position, to a loading tray (18) belonging to the gun.
The invention relates to a shell (1) intended for firing from a weapon (6), preferably a mortar weapon (6), the shell (1) being designed for securing the shell (1) in a mortar weapon (6) in order thereby to prevent movement of the shell (1) when adjusting the angle of elevation of the weapon (6). According to the invention this is achieved in that the shell (1) comprises a locking part (19, 28, 37), the locking part (19, 28, 37) forming an integral part of the shell (1) and being designed so that the shell (1) after ramming home is locked to a corresponding securing part (19) in the mortar (6). The invention also relates to a mortar (6) intended for firing said shell (1), the mortar (6) being characterized in that the mortar (6) comprises a corresponding securing part (19) for locking the shell (1).
The present invention relates to a method and a shell (1) for achieving variable firing range and effect when firing from a launcher, which shell (1) contains a firing charge (10), a rocket motor charge (6) with gas outlet (8), a rocket motor nozzle (9) and an active part (5). According to the invention, this is achieved by virtue of the fact that the shell (1) also contains a release mechanism (15) for releasing the rocket motor nozzle (9) from the rocket motor charge (6) after a time delay determined with regard to firing range and effect, and that the rocket motor charge (6) comprises a propellant which is detonable.

Method of increasing the range of a subcalibre shell and subcalibre shells with a long range
The invention relates to a method for increasing the range of shells (1, 8, 13) charged with an explosive substance and other types of shell, which function as carriers of the one or other type of active payload. The method according to the invention thus provides an opportunity for increasing the range of fire of most types of artillery piece by increasing the muzzle velocity and the gliding flight capability of shells or projectiles fired from them, but without the need to increase the energy content in the propellant charges utilized for firing the shells or the projectiles concerned. The novelty proposed in accordance with the invention instead represents a radical modification to the design of the shell (1, 8, 13) utilized in conjunction therewith. The invention also relates to a shell charged with an explosive substance or provided with some other active payload which has been given a long range.
The invention relates to a warhead comprising a first and a second part, the parts being arranged relative to one another along a longitudinal axis, the first part comprising a first explosive section, a casing, and a plurality of projectiles enclosed in the casing. The second part comprises an element designed to control the working of the warhead as a function of a control signal. The fact that the functioning of the warhead can be controlled means that the warhead can defeat a plurality of different targets, which makes the warhead versatile.

The invention relates to a method and device for the determination of the roll angle φ of a rotating body, such as a shell, utilizing sensors for the detection of rotation signals in a body-fixed coordinate system. According to the invention, a new filter device is proposed to handle moment interferences to which the body is subjected, for example, caused by wind turbulence in the atmosphere or similar phenomena. The interferences are eliminated by useful measurement signals emitted by the sensors being mixed down to the frequency zero and by the sensors' rotation signals thereafter being low-pass filtered.
