Definitions

  • the invention relates to an explosive projectile with a projectile body according to the preamble of claim 1.
  • An explosive device grenade is known from EP 0 068 533 B1. This has a projectile body and a ballistic hood arranged in front of the projectile body. An explosive charge with a fire charge arranged in front of the explosive charge is provided within the projectile body.
  • a detonator is located behind the explosive charge.
  • the explosive charge has a conical tip at its front end, this tip is surrounded by a fire charge, the fire charge being arranged within a conical recess in the projectile body. With this arrangement, the fire charge is distributed over a relatively large area by the explosive charge.
  • an explosive projectile with a splinter effect is known from EP 0 101 795 B1.
  • Pre-shaped splinters are arranged both in the projectile body and in the rear part of the igniter.
  • an explosive projectile in which a projectile body provided with splinters in the cylindrical region has a continuous, axial opening at its conical tip, so that continuous ignition from a base igniter to an explosive charge arranged in a projectile hood is guaranteed.
  • the bullet hood has splinters preformed on the circumference, these being arranged between two shells.
  • the splinters in the projectile hood create a splintering effect in the direction of the projectile axis, but due to a splinter-free area, i.e. without preformed splinters, a relatively large angle around the projectile axis will remain without splinters.
  • the object of the invention is seen in proposing an explosive fragmentation projectile with a depth effect, in which the fragmentation effect also comes into play in the firing direction.
  • the explosive projectile according to the invention is for armored cannons with a combat distance of up to approx. 3,500 m and for the fight against so-called soft and semi-hard targets.
  • the bullet train has, in a known manner, almost no significant path deviation at this target distance, so that there is in itself a high accuracy of accuracy, which is necessary for combating narrowly limited and smaller targets, such as, for example, portable or motorized anti-tank systems.
  • a high splinter density is achieved in the lateral and in particular in the front area of the projectile. Even with a greater combat distance and the associated relatively large scatter of the detonation point in the firing direction, a high probability of destruction is realized.
  • the matrix allows any shape of the splinter body.
  • the binding forces of the matrix are sufficient for easy assembly and handling during assembly. On the other hand, the binding forces are so low that the detonation results in the unhindered disassembly and thus even distribution of the preformed splinters.
  • the matrix in the splinter body also provides the necessary dimensional stability in relation to the feed shock into the cartridge chamber of the weapon and during firing.
  • the space available for the splinter body within the hood is optimally used without the aerodynamics of the projectile being disadvantaged.
  • the shape of the splinter body as a truncated cone causes a good spatial splinter distribution with a good depth effect.
  • the flat end face of the splinter body allows inexpensive manufacture.
  • the plastic body fixes the splinter body within the hood in a simple manner due to the flat end face of the splinter body.
  • the plastic body due to its low density, the plastic body does not affect the acceleration of the projectile, the spreading of the splinter or the acceleration of the splinter.
  • a splinter body is proposed, which can be used with great effect for a so-called sabot projectile. Due to the smaller floor cross section, a relatively small volume is available for the splinter body. The selected shape and design of the splinter body ensures, supported by the higher bullet speed, a large splinter density and splinter speed over long ranges.
  • the explosive in the front, relatively small cylindrical section brings about the required radial speed component for an ideal spatial splinter distribution in air detonation.
  • the cylindrical section offers additional use of the space in the hood, e.g. B. by electronic components, such as. B. sensors or components for the energy supply of the electronic ground igniter. Such components can be supported on the projectile body without acceleration due to the cylindrical portion and also attached.
  • the conical tip protruding from the splinter body favors the propagation of the pressure wave of the explosive for the premature disassembly of the hood.
  • the full-caliber floor is suitable for larger target areas.
  • relatively high bullet speeds can be achieved due to the ballistically more favorable bullet. This means that narrowly delimited, smaller targets can be fought with relative accuracy over a relatively long distance.
  • the ballistic hood made of steel ensures that, on the one hand, the splinter body remains dimensionally stable when the projectile is fired, and on the other hand the hood is arranged by relatively large splinters - approximately in the size of the form splinters - the splintering effect of said splinter bodies and that arranged on the circumference of the projectile Splinter added.
  • the free space in the hood is used to substantially increase the fragment density in the weft direction.
  • Essential to the invention is the large number of fragments in front of the end face of the projectile body and the relatively large-area conical sections of the projectile body. This means that in the case of exclusive air detonation, i.e. at an average of approx. 10 m above ground the so-called blind splinter area (see also the description with drawing) is covered with a relatively high splinter density and splinter energy. In the interaction of the front splinter body with the splinter jacket arranged on the circumference of the projectile body, there is a high splinter effect over a relatively large solid angle.
  • a full-caliber projectile 1 consists of a projectile body 2, a guide band 3, a projectile detonator 4, an explosive charge 5, a hood 6, a plastic body 7 made of polyurethane foam and a splinter body 8.
  • Balls 20 made of heavy metal are embedded in a cylindrical section 25 of the projectile body 2.
  • the projectile body which is closed at the front and designed as a cone 21, has a cylindrical section 22 with a conical tip 23.
  • the wall thickness of the cone 21 becomes smaller as the diameter decreases.
  • the wall thicknesses decrease further over the cylindrical section 22 to the tip 23.
  • the splinter body 8 extends between the hood 6, the cone 21 and between the cylindrical section 22.
  • the conical tip 23 projects beyond an end face 24 of the splinter body 8.
  • the balls 20 of the splinter body 8 lie in a matrix made of polyurethane foam.
  • the plastic body 7 lies against the end face 24 of the splinter body 8 as well as against the inner surface of the hood 6.
  • the projectile 1 is fired from a tank cannon, not shown, and flies on a track 26 which includes an angle 27 of approximately 1 ° with respect to the horizontal 49.
  • Projectile 1 detonates above target area 50 (at a combat distance of approx. 2,500 m) at a height 53 of approx. 10 m.
  • Projectile section 25 generates a splinter cone 31 with an angle of approx. 40 °.
  • the splinter body 8 produces a subsequent splinter cone 28 with an angle of approximately 30 °.
  • a very small central area 29 of approximately 5 ° has relatively few splinters.
  • the entire area 52 with a high probability of destruction is approximately 75 ° to the horizontal. In this way, standing targets, such as vehicles, and targets covered by an earth wall 51 are detected.
  • a sub-caliber projectile 30 consists of a projectile body 32 with embedded balls 20, a ground igniter 34, an explosive charge 35, a hood 36, a plastic body 37 and a splinter body 38.
  • the projectile body 32 is arranged in a drive pot 40 in a known manner.
  • the projectile body 32 has a closed tip in the form of a cone 45.
  • the splinter body 38 completely covers the cone 45 and projects beyond it by the distance 46, which corresponds to approximately 30% of the outer diameter 47 of the splitter body.
  • the remaining volume of the hood 36 is filled by the plastic body 37 made of polyurethane foam.
  • the principle of operation corresponds to the full-caliber floor 1, as described for FIG. 2.
  • the corresponding splinter cones are somewhat smaller.
  • the more accurate floor 30 is therefore used for relatively narrowly defined goals.
  • a splinter body 59 of a projectile 60 has a tapering section 62 within the hood 36 in the firing direction 61.
  • This section 62 has the shape of a cone flattened on its end face. Other shapes for section 62 can also be selected.
  • Essential for the splinter body 59 is the increase in the splinter density in the weft direction 61 compared to the splinter bodies 8 already described; 38.
  • This splinter body 59 can be used both in the full-caliber floor 1 and in the lower-caliber floor 30.
  • the effect of the splinter body 59 of FIG. 4 can be seen with a lower-caliber floor 70.
  • the projectile 70 detonates above the target area 50 at a height 71 of approximately 5 m.
  • the splinters 20 of the splinter body 59 are located in the region 74. Provided that the number of balls 20 is increased by approximately 20% compared to the splinter body 38 due to the tapering section 62, this leads to an increase in the splinter density in the weft direction 61, namely in an angular range 75 from 0 to a maximum of 10 ° by approximately 50%.
  • the splinters 20 of the projectile body 32 lie in the area 72.
  • the angular range 71 corresponds to approximately 20 °
  • the angular range 72 corresponds to approximately 45 °
  • an angular range 73 corresponds to approximately 15 °.
