  • Patent number: 11035655
    Abstract: A spin-stabilized artillery projectile having at least one driving band and at least one obturator, wherein the driving band contains at least one compensating groove, and wherein the at least one obturator is arranged in the compensating groove of the driving band. The cross-section of the compensating groove, is preferably trapezoidal, but can also be rectangular or square. As a result, a complete detachment of the obturator is achieved and residues are avoided.

  • Publication number: 20150241181
    Abstract: A projectile with several flare bodies, which are eccentrically housed in the body of the projectile and are ignited by at least one delay element for each flare body. The expulsion gases are conveyed from the ogive of the projectile to the delay elements through filler elements that form a channel in the center of the projectile for the expulsion gases.

  • Patent number: 8739671
    Abstract: A method is provided for producing a large-calibre explosive projectile having a projectile casing with an ogival front part, which surrounds an internal area filled with a plastic-bonded explosive charge and, at a nose end, has a mouth closed by a nose fuze, wherein an elastic liner is arranged between the explosive charge and the inner wall of the projectile casing. The projectile casing is produced in two parts, such that, in the direction of the longitudinal axis of the projectile casing, a tail-end projectile casing section and an annular front projectile casing section, which contains the mouth, can be connected to one another in the area of the ogival front part, via a screw connection. The liner is introduced into the tail-end projectile casing section and the explosive charge is introduced into the liner before the two projectile casing sections are connected to one another.
