Description

The invention relates to a balancing projectile according to the waiter Concept of claim 1.

Such a balancing projectile is shown in DE-PS 14 28 679 posed and is both as spin-stabilized as well designed as an arrow-stabilized balancing projectile. That be Known projectile has several cores that point axially are arranged one behind the other, being in an off leadership example the front core is tapered towards the rear rejuvenated.

The purpose of this arrangement is to create a multi-board armor penetrating, with the rear core from the front core in the first plate of the multi-platen armor created breakthrough if possible prevents from happening.

Combating armored targets isn't just that a breakthrough, but also a sufficient effect  to the objects protected by the armor strive.

Since one is generally there with bullets can assume that after the actual tank punch one for the effect behind the pan sufficient amount of residual energy is available, the object of the invention based on the well-known balancing bullet mentioned at the beginning to further develop that from the floor to passing armor using the so called split off several secondary storeys so that that a large solid angle behind the struck Armor is smeared from the secondary floors.

This object is achieved by the features of claim 1 solved.

Here is behind the conical end of the front core one to this coaxial bundle of driftable Parts arranged, which in the delay of the their part due to the penetration of armor run up on its conical end and thereby radially to be flung outwards so that they separate the drivable parts form the secondary storeys.

This will quickly disassemble the Ge laterally lap or splitting off and radial acceleration of the Secondary floors ensured after breakthrough, which besides heavy armor also for targets with Ratio to the total penetration of the projectile thin or weak armor, such as steel shock armor, light metal superstructures and other protection superstructure applies. In the case of multiple armor, appropriate configuration of the balancing device according to the invention the desired secondary effect, i.e. the Ab splitting of secondary floors, also behind each one individual disk accessible.  

While to radially disassemble the projectile at swirl stabilized projectiles can use the centrifugal force is, the balancing projectile according to the invention needs the Centrifugal force for radial acceleration of the secondary arm Do not shoot and is therefore also special for wings stabilized bullets can be used.

Through the balancing bullet according to the invention, the fol advantages achieved:

  • 1. There will be an increase in the residual effect without essential achieved a reduction in the penetration rate.
  • 2. Dismantling the projectile is also easy Armor possible - this makes it disproportionate Breakthrough performance avoided;
  • 3. they are not bullets subject to aging parts necessary;
  • 4. by appropriate choice of components of the he storey according to the invention is also a short-term one Adaptation to changing needs possible;
  • 5. It is a relatively simple floor construction;
  • 6. The principle is independent in its effectiveness the impact angle of the projectile;
  • 7th with bulkheads an increase in Effect achieved behind each plate;
  • 8. The secondary floors depend on Desire for a variety of small bullets or too projectiles capable of endballistic performance;
  • 9. The radially accelerated secondary floors can ever but in turn be stable flying projectiles again;
  • 10. The principle is with both arrow and spin-stabilized balancing bullets applicable; and
  • 11. in the case of arrow-stabilized balancing bullets is the The speed of the secondary floors is insignificant at the original speed of impact of the entire balancing projectile.

Preferred embodiments of the invention are the wide one ren claims.

In the drawing, 1 a different embodiment is shown in FIGS. To 4 each show an arrow-stabilized projectile according to the invention.

Fig. 1 shows the schematic diagram of a projectile according to the invention to achieve the greatest possible secondary effect. The armor-piercing main part 1 of the projectile has a conical end 1 a . It is supported with this by means of a relatively easily deformable body 2 on the cone of a further armor-piercing element 3 arranged behind it. Around this rear floor core there is a wreath of projectiles 4 , which are adapted to the cone 1 a of the first core 1 and 5 based on the Geschoßbo. These sub-projectiles or parts that can be driven radially apart in this and the other parts have the shape of elongated cylindrical rods. You can also have a prismatic cross-section to make better use of the available floor cross-section, so that the area occupied by the cross-sections of the sub-projectiles is an annular surface. When hitting a target, the preliminary core 1 is now delayed after destroying the weak outer hood 8 which is necessary for external ballistics. Characterized it issues via its conical part of the projectile ring 4 is a radial component, so that the individual sub-projectiles 4, the thin shell casing 6 punctured. This radial acceleration of the edge projectiles 4 is further supported by the fact that it is squeezed between the cores 1 and 3 of the body 2 and since it also pushes outwards through the individual projectiles.

The effectiveness of this arrangement was determined on the basis of the projectiles shown in FIGS. 2 and 3. With such a structural breakdown, the flow of the individual floor elements becomes clear. The radially squeezable body 2 is missing in the projectile according to FIG. 2, in which the rear cone 30 of the armor-piercing core 31 drives the projectiles 32 apart. Fig. 3 contains in addition to the functional principle shown in Fig. 1, realized in the rear floor part still a second part projectile ring 20 with a modified, plastically deforming intermediate piece 21 (formed here as a sleeve) in the front floor part. On impact, the plastically deformable sleeve 21 is driven radially apart from the rear cone 22 of the armor-piercing and expansion core 23 and the front cone 25 of the central core 24 due to the different deceleration of these cores.

Fig. 4 shows a projectile design, which is to be understood as an extreme case of the storey structure shown in Fig. 2: the storey consists of a bundle of basements 11 without an actual, except for a small, the radial deformation initiating, very small vorde ren core 10 Projectile core in a sleeve 12 . Compared to a solid stick storey, the penetration performance of this projectile drops sharply, particularly in the case of massive armouring, but it can lead to a considerable breadth of effect, particularly in bulkhead armor and especially in light metal arrangements (flight destination).

Claims (5)
