Definitions

  • the invention relates to a tandem warhead with a secondary floor.
  • the situation is different for a warhead according to FR-A1 1.002.092.
  • a hollow charge at the top is separated from a subsequent balancing projectile by a vapor protection.
  • the steam protection is designed as a caliber-sized disc and sits on the floor arch of the balancing floor. This is to protect the ogive of the balancing bullet, while the shaped charge creates a bullet channel in the target.
  • the material of the steam protection is not specified.
  • the object of the invention is to propose a functionally reliable arrangement of a secondary storey in a tandem warhead.
  • the secondary floor is designed as a frag grenade with a detonator.
  • the secondary storey is held in a form-fitting and non-positive manner in a tube piece of the tandem warhead designed as a holding tube via a threaded connection.
  • a steam protection secures the secondary storey directly at the threaded connection.
  • the plume protection is compressed into the annular space which narrows towards the rear, thereby achieving the actual sealing effect.
  • a tapered section of the housing of the tandem warhead which is integrally connected to the pipe section, is broken up. This leads to the thread connection being broken, so that the secondary projectile, due to its inertia, has its free flight phase until it reaches a crater of a bullet channel caused by the shaped charge.
  • the fastening parts and the steam protection can be produced easily and inexpensively.
  • the functional safety of these parts is also available.
  • a secondary storey 1 is mounted in a tube section 2 of a housing 3 of a tandem warhead 4 and is connected to the housing 3 via a threaded connection 5.
  • a steam protection is designated 6.
  • the front part of the tandem warhead 4 has a detonator 7 and a shaped charge 8 with an igniter 9.
  • the secondary storey 1 consists of two housing parts 10, 11 screwed to one another via a thread 35. Ogives 44, 45 are provided on the housing parts 10, 11. Both ogives 44, 45 have a splinter charge 23, 24. The fragmentary charges 23, 24 are covered by sleeves 67, 68 against active charges 13, 14 consisting of explosives. An igniter 20 separates the two active charges 13, 14 from one another.
  • the housing 3 has a conical section 87 with the cylindrical pipe section 2 arranged thereon in one piece. With this pipe section 2, a bottom 88 is screwed to a recess 89 corresponding to the ogive 46 via a threaded connection 90. The ogive 46 thus lies on the floor 88 with a very large surface contact. As a result, the threaded connection 5 represents a so-called counter lock. It ensures the secure attachment of the secondary storey 1 in the tandem warhead 4 during transport.
  • the threaded connection 5 between the pipe section 2 and the secondary floor 1 is secured against loosening in a conventional manner, for example by a securing lacquer.
  • the steam protection 6 is wedge-shaped in the direction of the shaped charge 8.
  • an end face 91 lies at an acute angle 102 to the main axis 92 of the tandem warhead 4.
  • the rear faces 93, 94 lie against a conical surface 95 and against a bottom surface 96 lying at right angles to the main axis 92.
  • This angle 102 extends between 30 ° and 50 °, preferably 45 °, as drawn.
  • the steam protection 6 lies in a wedge-shaped bottom space 101 which is formed by the conical section 87 of the housing 3 and the secondary floor 1.
  • the inner contour of the vapor protection 6 is composed of a sealing lip 97 which rests on the secondary storey 1 and an annular support surface 98 which is also annular.
  • the thread 86 of the threaded connection 5 lies at the beginning of the pipe section 2. This is followed by a free annular space 99 in the direction of the bottom 88. This annular space 99 is delimited in the rear part by the floor 88. The gap 100 of the annular space 99 is on average one to two millimeters. The length of the annular space 99 is approximately one third of the length of the secondary floor 1.
  • the hollow charge 8 creates a crater with a subsequent bullet channel in the cover.
  • the rear explosive vapors influence both the vapor protection 6 and the housing 3.
  • the vapor protection 6 When viewed in a stretched manner over time, the vapor protection 6 is compressed due to the high pressure of the explosive vapor within the still existing housing 3, so that the explosive vapor cannot reach the floor 88 through the threaded connection.
  • the sealing lip 97 is pressed on the secondary floor 4 in the corresponding direction on the circumference.
  • the vapor protection 6 naturally does not keep off the explosive vapor in the long term, but only in the crucial microsecond range. In this time range, the conical end face 91 guides the pressure maximum slightly outwards, that is to say away from the threaded connection 5.
  • the housing 3 breaks together with the threaded connection 5, the secondary storey 1 already being in a forward movement due to its inertia. Due to the opening of the housing 3, there is a pressure relief with respect to the secondary storey 1, so that there is no longer a risk of the secondary storey 1 being broken open due to the explosive vapor.
  • the pipe section 2 remains stable due to the swath protection, ie it is not destroyed by the detonation swaths. This results in a position stabilization during the forward movement of the secondary storey 1 due to the annular space 99 of the secondary storey 1. This ensures that the secondary storey 1 receives a certain guidance in order to be able to carry out a stable free flight phase, namely until it hits the crater of the bullet channel.
  • the steam protection consists of an elastic, i.e. compressible plastic.
  • PVC and also PP, PA, PE, POM or PTFE are suitable for this.
