Definitions

  • the invention relates to a projectile according to the preamble of claim 1, and it is based on the object of the projectile according to the European patent application with the application number 83111016.8 (publication number 0 11 712 A1) for use in an automatic tube weapon for the purpose of combating flight targets with a comparatively reduced flight time or greater combat distance on the one hand and earth targets, for example armored personnel carriers, on the other hand advantageously to develop further into a multi-purpose projectile with a favorable ratio between splinter and balancing effect.
  • a first flight floor P1 is enclosed on the circumference in a positive-locking zone 30 by a sabot 22.
  • the missile P1 has a stabilizing tail unit 20 on the rear of a body 10.
  • a body 12 with a body 14 arranged on the tip side adjoins the latter on the front side.
  • the sabot 22 has a front part 48 with an air pocket 54 and a rear part 50 with a gas pressure receiving surface 58.
  • a propellant charge sleeve 46 is connected to the propellant cage 22 in strangle grooves 62.
  • the front part 48 and rear part 50 of the sabot 22 are connected to one another in a stepless manner by a sheath 44 provided with predetermined breaking points not shown along the longitudinal axes. This is discussed in connection with FIG. 3.
  • the missile P1 has a high-strength shell 38, for example made of steel.
  • the peripheral region 28 it is provided with positive locking means (not shown) for forming the positive locking zone 30 already mentioned.
  • the latter extends on the front and back beyond a joint area 16 in which the bodies 10 and 12 are connected to one another, for example by brazing.
  • the casing 38 extends from the rear of the projectile to a front edge 25 which is designed in the form of a knife. In the process, their wall thickness continuously decreases in an area 24.
  • the interior of the shell 38 for receiving the two bodies 10 and 12 is of circular cylindrical design with the same diameter.
  • the sheath 38 is connected to the two bodies 10 and 12, for example by brazing.
  • the wall thickness thereof decreases, and the casing 38 is formed there on the circumference as a carrier for the stabilizing tail unit 20 and on the inside as a receptacle 32 for a tracer set 34.
  • the materials of the two bodies 10 and 12 are characterized by a high proportion of at least one metallic element with a density of at least 18 g.cm. It can be both depleted uranium and tungsten. In the latter case, at least 90% (weight) of tungsten is present in a binder phase in the form of an alloy which contains at least iron and nickel. As a result, the material has a specifiable ductility. With a comparable tungsten content, the material of the body 12 is comparatively less ductile. It is more brittle and therefore easier to dismantle. As a result, numerous fragments of different sizes are formed when the projectile hits the body 12.
  • the sheath 38 absorbs transverse and longitudinal forces which occur at least during handling in connection with a machine gun and which could damage both the body 12 and its connection to the body 10 in the impact area 16.
  • the focus is on the transport determined by the belt feeder, the process of insertion into the cargo space and the acceleration in the gun barrel, which is fired at intervals.
  • a sabot 23 (instead of the casing 38 in FIG. 1) absorbs transverse and longitudinal forces. Therefore, it has an extended support area 40, 42 on the front and rear.
  • the positive-locking zone 30 is limited to the body 10.
  • the bodies 10 and 12 are additionally connected to one another in a centering manner by means of a pin 52.
  • the support area 40 is surrounded on the outside by an air pocket 56.
  • the support area 42 is delimited on the outside by a gas pressure receiving surface 60; as a result, it is advantageously pressed radially against the missile P2 under the gas pressure building up during the shot development.
  • the sheathing 44 provided with predetermined breaking points not shown along the longitudinal axis gives the sabot 22, 23 a smooth circumferential surface and facilitates the transport and feeding process.
  • the material of the body 14 arranged on the tip side first becomes effective. It is preferably pyrophoric. As already mentioned, the material of the body 12 breaks down into numerous fragments of different sizes.
  • the projectile according to the invention is distinguished by a higher airspeed compared to spin-stabilized projectiles. This increases the range and increases the likelihood of striking. This applies to both flight targets and earthbound targets, preferably armored personnel carriers.
