Definitions

  • the invention relates to a secondary floor for a tandem warhead according to the preamble of claim 1.
  • a warhead with a tandem charge is known from EP-A1-0 583 642.
  • the warhead has a main charge in the form of a shaped charge and a smaller-sized additional charge.
  • the secondary projectile designed as a fragmentary projectile, penetrates the target through this channel and detonates behind the target with a splintering effect.
  • the secondary storey is moved through the channel solely due to its inertia when the warhead hits.
  • a separate acceleration charge for the secondary floor is not necessary.
  • the fragmentation effect is caused by the explosive charge and the housing of the secondary floor. Due to the design of the secondary storey, the splintering effect is mainly in the direction of the shot, with only a small splintering effect occurring directly in the vicinity of the cover.
  • an explosive charge and ogive-shaped construction splinters are also provided in the rear of the projectile.
  • the rear explosive charge is ignited by a center-mounted detonator, which detonator separates the front explosive charge from the rear explosive charge.
  • the front explosive charge is ignited via an ignition amplifier, while the rear explosive charge requires a transmission detonator and a downstream ignition transmitter.
  • This ignition transmitter initiates the explosive charge on the rear side eccentrically, that is, on the outer edge of the explosive charge.
  • This one-sided ignition of the Explosive charge designed as a hemisphere has a very different fragment density in the target area.
  • the energy of the construction splinters varies accordingly.
  • This transfer of the ignition should be structurally simple and inexpensive.
  • Essential for the invention is the symmetrical and large-area ignition transmission to the rear active charge.
  • the effectiveness of the rear active load corresponds to the front active load.
  • the large-area ignition of the front active charge is an advantage.
  • a functionally reliable transmission of the ignition is present in claim 1.
  • the thin wall sections of the igniter, which separate the booster charge from explosives from the tongue-like explosive poles of the rear active charge, ensure the simultaneous ignition of the latter.
  • a secondary storey 1 is mounted in a tube section 2 of a housing 3 of a tandem warhead 4, which is only partially drawn, and secured via a threaded connection 5.
  • a steam protection is designated 6.
  • the secondary storey 1 consists of two housing parts 10, 11 screwed together at 109, an igniter 12, a two-part explosive charge 13, 14 and fragmentary charges 15, 16 with casings 17, 18.
  • the igniter 12 according to FIGS. 2 and 4 consists of an electrically controllable igniter 20 with a detonator 21, a thread 42 and an igniter 25 screwed to the igniter 20.
  • the igniter 25 has a housing 26 with two flanges 22 and with a central pin 27 on the igniter side. In the housing 26 there are recesses 28 to 31 with an amplifier charge 32 made of explosives.
  • the booster charge 32 is disc-shaped in the direction of the front active charge 13 and has a diameter 33 which almost corresponds to the diameter 34 of the front active charge 13.
  • Two tongue-like explosive poles 50 are connected in one piece to the rear active charge 14. After the detonator 12 is arranged completely in a cylindrical metal sleeve 52 made of aluminum, the space required for the explosive poles 50 is created by corresponding recesses 55 on the housing part 11. The metal sleeve 52 completely encapsulates the rear active charge 14. An elastic element between the housing parts 10 is designated 110. One of the flanges 22 is pinned at 111.
  • two thin-walled wall sections 59 are provided on the housing 26, so that the ignition from the booster charge 32 to the explosive poles 50 can take place - that is, in two ways.
  • the cross sections of the explosive poles 50 are dimensioned such that the ignition to the explosive material block 19 of the rear active charge 14 is ensured.
  • the tandem warhead 4 strikes a cover (not shown), a hollow channel is created in the cover by the shaped charge (also not shown).
  • the secondary floor detached from the housing 3 penetrates through this penetration channel.
  • the detonator 21 of the igniter 20 ignites the booster charge 32 on the basis of a correspondingly set time delay.
  • the front active charge 13 is ignited and at the same time the explosive poles 50 are ignited, in which the housing 26 is penetrated in the overfire areas 60.
  • the opposing explosive poles 50 conduct the explosive pulse symmetrically over a neck area 61 to the explosive material block 19.
  • the simultaneous detonation of the front and rear active charges 13, 14 leads to both a front splinter distribution and a rear splinter distribution.
  • the splinter distribution due to the rear active charge 14 is just large in the direction of the bullet channel and its surrounding field.
