Definitions

  • the invention relates to a wing-stabilized shaped-charge projectile designed as a test ammunition with a caliber-like tail unit, which has a front and a rear explosive chamber and which is provided with an ignition rod on the end face of the projectile casing.
  • Hollow charge bullets achieve their armor-piercing effect with the help of the so-called hollow charge effect.
  • This effect is essentially due to the fact that, as a result of the detonation of the explosive, the insert elements which collide in the middle of the charge form a metal beam called a spike, which emerges from the charge cavity at speeds of up to 10 5 m / s and, because of this high speed, also thick armor penetrates.
  • the ignition rod provided on the end face of the projectile shell initiates the ignition while maintaining the distance necessary for the shaped charge development - the effect of a shaped charge depends on the distance of the shaped charge from the armor at the time of the detonation of the explosive.
  • Wing-stabilized shaped charge bullets are provided on their rear part with a tail unit which, due to the aerodynamic flow, generates air forces and thus counter-moments as soon as the projectile is deflected from its normal flight position by interference.
  • the tail unit is generally made of aluminum.
  • Firing ammunition is used for training on the weapon, d. H. to practice loading, judging and meeting. This presupposes that this ammunition has exactly the same ballistics and thus the same shape, the same weight and the same center of gravity as the combat ammunition. Training ammunition is also used for functional and acceptance tests on weapons.
  • Hollow-charge projectiles designed as training ammunition have the same shell as the combat ammunition. Instead of the explosive charge, an inert mass of the same density is pressed or poured into the shell.
  • the ignition rod and the part of the projectile casing forming the rear explosive chamber are made of aluminum, while the part of the projectile casing forming the front explosive chamber is made of steel.
  • the individual parts of the shell are screwed together - as in the case of combat ammunition - and must be processed accordingly.
  • the production of the known training ammunition requires a very high outlay and therefore very high costs.
  • FR-A-2 407 453 discloses a wing-stabilized hollow charge simulation projectile designed as a test ammunition with a caliber-like tail unit, which has a front and a rear explosive chamber and which is provided with an ignition rod on the end face of the projectile casing, the entire projectile casing, including the ignition rod, through is made of the same or similar material existing parts that are inextricably linked.
  • This well-known shaped charge projectile however, also requires a high manufacturing effort.
  • FR-A-2 536 683 relates to a different type of ammunition than the training projectile according to the present patent application.
  • the projectile according to FR-A-2 536 683 is an explosive grenade, s. see Figure 1102, page 467. Explosive grenades of this type have the effect that the shell of the projectile is broken down into individual fragments when it strikes the target and, due to the acceleration from the shell of the explosive, has a considerable amount of energy and therefore a destructive effect.
  • the projectile casing is designed with a relatively thick wall, cf. Page 467, last paragraph.
  • the subject matter of the invention is training ammunition for a shaped charge projectile.
  • shaped charge bullets have a relatively thin shell.
  • FR-A-2 536 683 for grenades it is previously known to produce a hollow body from two parts, one of the two, the cartridge case, preferably drop-forged, while the other, the projectile tip, is shaped or forged using the centrifuge method .
  • this method can only be used for thick walls. The method cannot be used for practice ammunition for shaped charge bullets with thin walls.
  • the invention is therefore based on the object of designing the shaped-charge projectile of the type mentioned at the beginning in such a way that it is simple and inexpensive to manufacture.
  • the solution to the problem is that the front end plate with the ignition rod and the part of the projectile shell forming the rear explosive chamber are formed as forgings and are welded to a cylindrical tube made of the same metal as the middle part.
  • the individual parts of the projectile casing do not need to be provided with a thread, which makes their manufacture considerably easier and cheaper, while on the other hand no contact corrosion can occur between the individual parts of the projectile casing.
  • forgings are simple and inexpensive to manufacture; Pipe are inexpensive mass products. If the forgings are made by drop forging, the interior of the parts already gets its final shape, so that no rework is required.
  • the front end plate with the ignition rod and the front explosive chamber or the front explosive chamber and the rear explosive chamber are designed as a one-piece forged part, so that the projectile casing consists of only a few individual parts and thus also has only a few connection points.
  • the parts can be produced by extrusion or stretch pressing.
  • the individual parts of the projectile casing are advantageously connected to one another by friction welding. It should be noted that the individual parts at the connection points must have a certain excess or that the tube forming the front explosive chamber must be correspondingly longer than in its final state. It is not necessary to process the inner friction welds.
  • a support disk is arranged between the front and the rear explosive chamber. This support disc prevents the projectile casing from being compressed by the high launch pressure of approximately 5000 bar, so that the projectile casing requires only a small wall thickness.
  • the front end plate and the ignition rod are provided with a bore.
  • This hole is used to provide the projectile with a low explosive charge and a detonator. On the one hand, this ensures that the point of impact is well marked, while on the other hand the projectile is at least partially disassembled, thereby preventing uncontrollable ricochets and ricochets.
  • an embodiment of the invention in side view, partly in section, is shown, namely the right half of a projectile shell in the unprocessed state and the left half finished and provided with a seal and a locking ring and with an empennage.
  • the projectile shell shown has a front explosive chamber 1 and a rear explosive chamber 2.
  • the front explosive chamber 1 is formed by a tube 3 and closed by means of an end plate 5 provided with an ignition rod 4.
  • the end plate 5 and the ignition rod 4 are provided with a bore 6.
  • the part 7 forming the rear explosive chamber 2 is provided at its end facing the front explosive chamber 1 with a recess 8 into which a support disc 9 is inserted.
  • the support disc 9 is non-positively due to the heat that has occurred during friction welding and is positively fixed by the protruding friction weld seam.
  • the rear explosive chamber 2 has at its end facing the front explosive chamber 1 a flange-like extension 10 against which an annular seal 11 abuts.
  • the seal 11 is held by a shrunk-on or pressed-on locking ring 12.
  • the part of the projectile casing which forms the rear explosive chamber is provided with an empennage 13.
  • the projectile shown in the drawing is produced in such a way that after overturning the end faces of the tube 3 and the connection points of the front end plate 5 with the ignition rod 4 and the part 7 forming the rear explosive chamber, the end plate 5 and the ignition rod 4 with the Bore 6 and part 7 are provided with the recess 8. Then the support disc 9 is inserted into the recess 8. Then the end plate 5, the tube 3 and the part 7 are connected to one another by friction welding. Subsequently, the projectile casing receives its final external shape by twisting, whereby previously attached centering receptacles ensure that the internal and external forms run centrally to the central axis of the projectile casing, so that no wall thickness differences can occur over the circumference. Finally, the seal 11 and the locking ring 12 are applied. Finally, the tail unit 13 is attached to the rear end of part 7.
