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.
Claims8
A holding device for counteracting a contact-impact event on elongated sub-projectiles when fired from a spin stabilized carrier shell, wherein the holding device comprises a core comprising at least two legs at least partially enclosing at least one sub-projectile each, wherein the holding device is deformed due to centrifugal forces influencing the sub-projectiles caused by rotation of the sub-projectiles such that the sub-projectiles are released in a controlled manner upon being fired from the carrier shell, wherein the core is wider in cross-section when viewed in a direction of a longitudinal axis of the holding device than any of the at least two legs, and wherein the holding device is molded, and the legs of the holding device are deformable relative to the core.
A process for counteracting the contact impact event of a sub-projectile fired from a spin stabilized carrier shell, wherein said process comprises the following steps:
- arranging sub-projectiles in a holding device comprising a core comprising at least two leas at least partially enclosing at least one sub-projectile each, wherein the holding device is adapted to be deformed due to centrifugal forces influencing the sub-projectiles caused by rotation of the sub-projectiles such that the sub-projectiles are released in a controlled manner upon being fired from the carrier shell, wherein the core is wider in cross-section when viewed in a direction of a longitudinal axis of the holding device than any of the at least two legs, and wherein the holding device is molded, and the legs of the holding device are deformable relative to the core.
- firing the sub-projectile from the carrier shell, and
- releasing the sub-projectiles from the holding device so that the legs of the holding device deform relative to the core and open up due to the centrifugal forces caused by rotation wherein the sub-projectiles are released in a controlled manner upon being fired from the carrier shell.
