  • Patent number: 11236980
    Abstract: A holding device and method for decreasing the contact-impact event on sub-projectiles when fired from a barrel, cylinder, carrier shell or the like includes a core and at least two legs that at least partially enclose at least one sub-projectile each. When a projectile is fired from a barrel or the like the sub-projectiles load the legs of the device which are deformed and open up and release the sub-projectiles in a controlled manner without tumbling which leads them to hit and penetrate their target with the short-side. A holding device including sub-projectiles and a projectile including the holding device are also provided.

  • Publication number: 20210180929
    Abstract: A payload container for providing a horizontal dispersion pattern of sub-projectiles suitable for combatting surface targets is in the form of a cylinder and includes at least two sub-projectiles arranged in a core enclosed by a container wall, wherein the sub-projectiles are linearly disposed. In addition, a projectile and use of the same include at least one payload container or a plurality of sequentially arranged payload containers displaced by a displacement angle relative to each other. The displacement angle is predetermined in such way so that the sub-projectiles are vertically lined at the time when the mechanical force from the carrier shell disappears and the sub-projectiles are spread to the left and to the right, providing a horizontal dispersion pattern.
