Definitions

  • the invention relates to a fragment projectile.
  • Fragment projectiles are known from, for example, German Patent No. DE 196 26 660 C2 corresponding to U.S. Pat. No. 5,900,580.
  • the subject of this patent is full-caliber projectiles having a projectile casing, which surrounds a hollow space that is filled in the front region with heavy-metal fragments. Additionally, an explosive charge is disposed inside the projectile casing. The charge is detonated at a predetermined time, and the fragments are accelerated, for example, in the direction of the target.
  • a drawback of fragment projectiles of this type is that they have a low rate of effectiveness, because the percentage by mass that causes the fragmentation effect is low relative to the projectile weight.
  • a fragment projectile comprising: a projectile casing that surrounds and defines a hollow space; heavy metal fragments at least partially filling the hollow space; and an ejector charge disposed at the rear of the hollow space to eject the fragments from the projectile casing when activated during the flight of the projectile.
  • the activation takes place at a predetermined time during flight due to a timer disposed on the projectile.
  • the invention is essentially based on the concept of omitting the use of explosives in the fragment projectile, and filling the space required for the explosive with fragments.
  • a relatively compact pyrotechnical ejector charge effects the ejection of the fragments at a desired, e.g., predetermined time.
  • the invention solves the problem of the firing reliability of explosives that is inherent to conventional fragment projectiles.
  • the fragment projectile As a subcaliber projectile in a simple manner. These projectiles possess a significantly higher muzzle velocity, and exhibit a much smaller drop in speed during flight. Furthermore, in fin-stabilized projectiles, the guidance assembly can be permanently mounted to the projectile. As a result, costs are further reduced and the hit probability is improved in comparison to full-caliber projectiles, in which collapsible guidance assemblies must usually be used.
  • FIGURE is a schematic cross-section view of a fin-stabilized sub-section projectile according to the invention providing with a propelling cage sabot
  • FIG. 1 there is shown a fin-stabilized, subcaliber fragment projectile 1 that is surrounded by an aluminum propelling cage sabot 2 , which is segmented in a known manner.
  • the projectile can be fired from a 120-mm caliber tank gun, for example.
  • the fragment projectile 1 includes a projectile casing 3 , having a hollow interior space 7 in which a packet of spherical fragments 4 comprised of heavy metal, e.g., tungsten (WSM), is disposed.
  • the projectile casing 3 also contains an ejector charge 5 at the rear of the hollow space and a programmable timer fuse 6 .
  • a fin stabilization unit 8 is affixed to the rear of the casing 3 .
  • the propellant cage sabot 2 initially is ejected in a known manner and the projectile 1 follows its flight trajectory to the vicinity of the target region.
  • the timer fuse 6 ignites the ejector charge 5 at a desired, in this case, predetermined time. The charge pushes the spherical fragments 4 out of the front of the projectile 1 by bursting the tip 7 .
  • predetermined fracture points are provided in the region of the projectile tip 7 . After the projectile tip 7 bursts, the residual projectile abruptly slows its speed because of the high air resistance. In contrast, at the time of the fragment ejection process, the relatively heavy spherical fragments 4 fly further into the target region at about the same original speed of the projectile.
  • the invention is not limited to the above-described exemplary embodiment.
  • non-spherical fragments can be used instead of spherical ones.
  • a heavy metal other than tungsten heavy metal can also be used as the fragment material.
  • the fragment projectile can also be spin-stabilized.
  • the timer fuse can also be replaced by a proximity fuse.
