Definitions

  • the invention relates to a splinter shell of a secondary storey of a tandem warhead according to the preamble of claim 1.
  • a tandem warhead with a hollow charge on the head side and a secondary floor downstream is known.
  • the shaped charge has the task of creating a bullet channel for the subsequent secondary storey in a cover. After the secondary floor emerges from the bullet channel, the secondary floor disintegrates with a splintering effect.
  • the splintering effect is caused by the detonative dismantling of the shell.
  • the object of the invention is to propose a functionally reliable secondary floor of a tandem warhead with increased splintering action, the secondary floor remaining unaffected by the explosive vapor after ignition of the shaped charge and also withstanding the stresses when passing through the bullet channel.
  • the splintering effect is significantly increased compared to the prior art, since the splinters are in contact with the projectile shell without a gap, namely under pretension.
  • the rounded shape of the two ogives results in a high density of splinters per solid angle with high splinter energy.
  • 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 together via a thread 35.
  • Ogives 44, 45 are on the housing parts 10, 11 intended.
  • the ogives 44, 45 are mirror images of one another and, with regard to their outer and inner contours, consist of a total of 4 circular arcs corresponding to the radii 46 to 49.
  • the thickness of the ogives is of the same thickness in each arc section, a cylindrical section 36 likewise being provided with this thickness.
  • Both ogives 44, 45 each have a fragmentary charge 23, 24 made of prefabricated fragments 39 on their inner wall 37, 38.
  • the fragmentation charge 24 also extends in the rear housing part 11 over the cylindrical section 36 and is designated 24.1 there.
  • the fragmentary charges 23, 24 are delimited by steps 65, 66 of the housing parts 10, 11 and 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 igniter 20 being firmly clamped at 69 by the two housing parts 10, 11.
  • the active charges 13, 14 are pressed against the sleeves 67, 68 and the fragment charges 23, 24 within the housing parts 10, 11 with high pressure.
  • the splitters 39 lie without a gap on the inner walls 37, 38 of the housing parts 10, 11, the sleeves 67, 68 having dome-shaped indentations in the region of the splitters 39 due to the high pressing pressure. This means that there is no gap between the active charges 13, 14 and the sleeves 67, 68 and between the sleeves 67 68 and the splinters 39.
  • the hollow charge 8 creates a crater with a subsequent bullet channel in the cover.
  • the secondary floor detached from the housing 3 penetrates through the crater and the bullet channel with its front ogive 44. Possibly occurring oscillations with the associated, oblique impact of the secondary storey 1 in the crater of the bullet channel have no adverse influence on the threading process.
  • the shape of the front ogive 44 enables the threading process in any case.
  • wall contacts are intercepted when the secondary storey 1 passes through the bullet channel.
  • the ogive shape of the ogive 44 also means that when you touch Obstacles in the bullet channel, such as the remains of steel reinforcements, are displaced.
  • the detonator 20 simultaneously ignites the active charges 13, 14. This ensures that a large fragmentation effect is achieved in the immediate area of the rear of the enemy cover. In particular, this is achieved by the rear active charge 14, in that a much larger fragment charge 24, 24.1 is provided there than in the front active charge 13.
  • the outer and inner contours of the ogives 44, 45 are essential for the splinter direction and the amount of splinters per solid angle due to the arc sections formed by arcs, see the radii 46-49.
  • the splintering action is composed of the splinters of the housing parts 10, 11 and the splinters 39 of the splinter charges 23, 24.
  • the fragmentation power of the rear active charge 14 is only partially effective in the direction of the penetrated wall of the cover. Due to the two egg-shaped ogives 43, 44 and the almost continuous explosives over the entire floor length of the secondary floor - in particular over almost the entire detonator length - there are 14 fragments of the housing sections 10, 11, namely the section, in addition to the partially effective fragmentation performance of the rear active charge 74 between the splinter charges 23 and 24 and a subsequent section 64 of the front splinter charge 23 plus the housing portion.
  • the insensitivity of the detonator 20 when the shaped charge 8 detonates and also when the secondary projectile 1 hits the crater of the bullet channel and finally the vibrations when the secondary bullet 1 passes through the bullet channel is based on the one-sided or flying "storage or fastening of the detonator 20 in the secondary floor 1.
  • the collar 70 is the only fastening point for the detonator 20 in connection with the housing parts 10, 11. In the axial direction of the secondary floor 1 there are only narrow contact surfaces due to the collars 72, 73 of the housing parts 10, 11.
  • the already described effect of the special detonator mounting of the detonator 20 in the secondary storey 1 is based on the short clamping length of the collar 70 of approximately 5 to 10% of the total length 77 of the detonator 20, which is dependent on the caliber. With a caliber of 47 mm, the clamping length of the federal 70 is approx. 6%.
  • the diameter 78 of the secondary storey 1 is approximately 33 to 40% of the total length 79, 37% being present in the aforementioned caliber. This ratio ensures a very good free-flying behavior, which begins when the secondary storey 1 is detached from the pipe section 2 of the tandem warhead 4, but is interrupted during the passage through the through-channel of a cover and ends with a minimal distance on the back of the cover by ignition of the secondary storey 1 .
  • An optimal splinter density and splinter energy is given by the length of the ogives 44, 45 in relation to the diameter 78 of the secondary storey 1. This ratio is about 65 to 75%, with 70% being present in the caliber mentioned.
  • the splinter power of the secondary storey is composed of the prefabricated splinters 39 and the splinters from the housing parts 10, 11.
  • the thickness 82 of the prefabricated splinters 39 in the direction of the blast is approximately 4.5 to 5% (in the case of the caliber of 47 mm, 4.7%) and the thickness 81 of the ogives 44, 45 in the direction of the blast (thickness of the splinters) is approximately 7 to 8.5% of the diameter 78 of the secondary storey 1 (caliber-related 7.8%).
  • the functions of the secondary storey 1 described above require a heavy-duty material and are ensured by a chromium-nickel steel alloyed with molybdenum.
