    • F42B12/18—Hollow charges in tandem arrangement

Definitions

  • the present invention relates to a method for a multiple hollow charge for bringing about an increased effect on or after penetration of protection, and a multiple hollow charge comprising at least a first and a second hollow charge arranged so as to act in essentially the same direction against a protection in order to penetrate the same, which hollow charges comprise an explosive charge with a liner, and which multiple hollow charge comprises means of detonation of the hollow charges, a hollow-charge jet for action against the protection being formed from each charge on detonation of a hollow charge.
  • hollow-charge jet relates to both extending jets and jets which have the nature of a projectile.
  • the object of the present invention is to increase the effect in connection with or after penetration of a protection, in particular armour protection.
  • This is achieved according to the method of the invention by causing a first hollow-charge jet from a first hollow charge and a second hollow-charge jet from a second hollow charge to collide in connection with penetration of the protection.
  • the expression in connection with penetration of the protection means a period of time which lasts from a point in time immediately before penetration to a point in time immediately after penetration. In the event of collision having started immediately before penetration of the protection, it is a prerequisite that the collision procedure continues at least during parts of the penetration phase.
  • the hollow charge according to the invention comprises means for causing the hollow-charge jets from at least the first and second hollow charges to collide in connection with penetration of the protection.
  • the hollow-charge jet formed last collides with jet parts from the jet formed first, such as a slug, tail fragments or other parts with lower velocity than the tip of the hollow-charge jet formed last, on or after passage through the protection, the material from both the jets is spread.
  • the spread material results in an increased effect according to one or more of the principles below.
  • a control arrangement is adapted to initiate the second hollow charge depending on the initiation of the first hollow charge so as to cause the hollow-charge jets of the hollow charges to collide.
  • the geometrical distances between component hollow charges are dimensioned so that the faster part of the second jet catches up the slower part of the first jet on or after penetration of the protection.
  • the hollow charges have a different geometrical shape and/or different explosive properties as a result of the use of different explosive substances, initiation principles or the like.
  • the component charges are preferably of the jet-forming or projectile-forming type.
  • the ignition sequence of the hollow charges can be either that the front charge of two hollow charges is ignited first or that the rear charge is ignited first.
  • the jet of the front hollow charge can also be included in a sectional area, which is to a greater or lesser extent empty, in the jet of the rear hollow charge.
  • parts other than the tip and tail of the hollow charges can be made to participate initially in the collision between two jets.
  • Figure 1 snows diagrammatically the activation of a multiple hollow charge of the tandem type at five points in time to illustrate the collision procedure
  • Figure 2 shows diagrammatically a multiple hollow charge with a control arrangement.
  • the multiple hollow charge 10 shown in Figure 1 comprises a first and a second hollow charge 11 and, respectively, 12.
  • the first hollow charge 11 comprises an explosive charge 13 with an associated liner 14, and the second hollow charge 12 comprises an explosive charge 15 with a liner 16.
  • the central axes of the hollow charges coincide on a common centre line 17. No detonators are shown but are assumed to be included according to any conventional solution.
  • Both the hollow charges can be of the projectile-forming type (IV) or of the jet-forming type (III). It is also possible for one hollow charge to be of the projectile-forming type and the other to be of the jet-forming type.
  • the rear charge 12 is ignited and a hollow-charge jet 19 is generated.
  • the charges follow essentially the same trajectory towards the target.
  • the jet 19 of the rear charge has caught up with the front hollow-charge jet 18 and a collision occurs between the faster parts of the rear hollow-charge jet and the rear parts of the front hollow charge, such as the slug, tail and other slow-moving parts.
  • the hollow-charge jets 18, 19 penetrate or have at this time T5 penetrated a protection (not shown), for example armour protection on a tank. Arrows 20 indicate that great radial forces occur.
  • the multiple hollow charge shown in Figure 2 is constructed in the same way as the multiple hollow charge shown in Figure 1 apart from that fact that a control arrangement 21 has been included between the two hollow charges.
  • the control arrangement 21 delays the generation of the jet produced last of two hollow-charge jets to such an extent that the tip of the hollow-charge jet produced later catches up the slower parts of the hollow charge produced first in connection with penetration of the protection.
  • the delay between the ignition of two hollow charges can be brought about in many different ways.
  • the decisive factors are inter alia the geometrical and other conditions in the charges and the distance from the charges to a predetermined collision point or a predetermined collision area in the vicinity of which a target to be combated is located.
  • the delay is determined by the time it takes for the slug of relatively great diameter of the hollow-charge jet produced first to move to a predetermined position in order to initiate in this case the front charge.
  • Other examples of known art are to use the delay which arises when a shock wave is made to travel a given predetermined distance in the shell structure or to include electronic delay circuits which prevent/delay initiation of charge two.
  • Such delays can also be brought about by pyrotechnic or explosive elements or mechanical arrangements. Combinations of the above delay methods can also be used.
  • the multiple hollow charge can thus comprise more than two hollow charges.
  • the hollow charges can be ignited in reverse order, that is to say a rear charge before a front charge and so forth.
  • the hollow charges can have different calibres, different geometries moreover and contain different materials.
