Definitions

  • Another known kinetic energy projectile of this type (see US Pat. No. 4,353,305) has a penetration tip at the front and a main penetration body at the rear, and a spacer sleeve is arranged between them. In this spacer there are balls as secondary floors. These bullets are thrown away in all directions either by the impact on the target or by an explosive or fire charge.
  • the spacer sleeve acts as a bumper to keep the waves reflected in the target when the projectile hits the main penetrator.
  • the secondary floors are preferably made of heavy metal.
  • the object of the present invention is now to achieve a projectile which is particularly suitable for different types of targets and which, when penetrating several plates of a target, causes the target to be destroyed as much as possible in the radial direction.
  • the projectile with which this object is achieved is characterized in that the filling consists of a powder whose grain size is less than 200 11 m.
  • the fragment jacket preferably has an integrated bottom at its rear end and its cavity can be closed at the front by the projectile tip, or the fragment jacket has an integrated projectile tip at the front and can be closed by a closure body at the rear.
  • the splinter jacket is preferably provided with predetermined breaking points by which the size of the individual splinters is determined. Instead of forming predetermined breaking points, the splinter jacket can be so brittle that it breaks into individual splinters when it penetrates the target.
  • the invention is particularly suitable for medium-caliber multipurpose projectiles (i.e. 20-40mm caliber) to combat aerial targets.
  • the projectile should preferably consist exclusively of metallic materials, preferably heavy metal.
  • metallic materials preferably heavy metal.
  • the use of an explosive, a fire charge and a detonator is dispensed with. Nevertheless, splinter and explosive effects should not be avoided, and a large depth of penetration is also desirable.
  • the projectile should have a high probability of being hit, which is achieved by a short flight time.
  • a high mass cross-sectional load is required in order to keep the braking of the projectile by the air resistance small.
  • a high cross-sectional mass load is achieved by using high-density materials.
  • a high initial speed is also achieved by using a sabot.
  • the projectile should have a large destructive effect, this is achieved by transferring as much of the kinetic energy as possible from the projectile to the target in order to be able to destroy a large volume in the target. To do this, however, it is necessary that the projectile does not shatter until it has penetrated the target, and not when it hits it. The radial effect of the projectile may therefore only take place after a certain delay. Armor plates and other target shields should be penetrated with as little energy as possible.
  • the projectile according to the invention has a penetrator 12 instead of the end body and a separate tip 13 instead of the integrated tip.
  • the projectile according to the invention has neither a closing body nor a penetrator at the rear end, but instead an integrated base 12 and instead of the integrated or separate tip, a tip designed as a closing body is provided.
  • the splinter jacket 10 will fragment after penetration of the projectile and will disintegrate into individual effective splinters.
  • a suitable heavy metal alloy is used for this splinter jacket 10, e.g. Tungsten or uranium. Sintered heavy metal, steel or hard metal is also suitable.
  • the splinter jacket should either be very brittle, or it should disintegrate into fragments 15 of a suitable size through predetermined breaking points 14 (see FIG. 4).
  • a material is preferably used, the extensibility of which is below approximately 10%.
  • the powdery filling is ejected in all directions after the bullet has penetrated.
  • a heavy metal powder is used for this filling, in particular tungsten powder, which has a high density of 10gr / cm3 and which has a grain size of about 10-200 11m, i.e. the grain size should be less than 200 11m. Heavy metal powder is preferably used for the filling.
  • the atomization of the filling in the target causes a pressure wave.
  • the closing body 12 in particular the penetrator 12, fulfills the task of penetrating as deep as possible into the target without disassembling.
  • a heavy metal alloy is also preferably used for the closure body or penetrator, but it has high toughness and can penetrate armor plates.
  • the end body 12 is cylindrical (Fig.1).
  • the penetrator 12 has a conical tip (FIG. 2).
  • the tip 13 is intended - when the bullet penetrates the target - to prevent the splinter jacket from being dismantled prematurely and the filling being atomized prematurely.
  • a tough, hard material is used for the tip 13.
  • the tip 13 can be made in one piece with the splinter jacket according to FIG.
  • the elements of the projectile in particular splinter jacket 10, filling 11 and penetrator 12, are coordinated with one another in such a way that a high level of synergy is achieved in the target.
  • Splinter jacket 10 and penetrator 12 ensure the required structural strength of the projectile during delivery to the weapon and during the launch phase.
