Definitions

  • a splinter shell and method of making same according to which at least two tubular bodies of strong but deformable material are coaxially arranged with regard to each other and located one within the other while being peripherally spaced from each other by the diameter of the desired splinter bodies to be incorporated in the shell, whereupon the splinter bodies are introduced between .the tubular bodies and, while the outermost tubular body is confined on its outside, the inner peripheral surface of the innermost tubular body is subjected to radially outwardly directed pressure to cause all of the tubular bodies to deform partially around the splinter bodies and to sandwich the same between the adjacent tubular bodies.
  • the present invention relates toa method of making splinter shells while using preformed, preferably ballshaped or pellet-like splinters, and also concerns splinter projectiles and splinter heads made according to thismethod.
  • a second metallic tubular body having an outer diameter which is smaller than the inner diameter of the outer tubular body by twice the maximum diameter of the splinters is centrally inserted into the first tubular body.
  • the splinter filling is poured into the thus formed tubu- Vlar cylindrical chamber, and finally by high pressure deformation the inner tubular body isby pressing its walls in' between the splinters deformed radially outwardly with regard to the rotation symmetric splinter shell and together with the outer tubular-body is plated so as to form a rotation symmetric splinter shell with a splinter mantle arranged in the boundary region of the tubes.
  • a one-layer or a multi-layer splinter mantle may be produced.
  • multi-layer splinter bodies forinstance, two or more tubes which are narrower by twice the splinter diameter are centrally arranged one within the other.
  • the tubular cylindrical hollow chambers are then filled with splinter bodies and the tubes are plated upon each other while fully enclosing the splinters and while simultaneously prefragmenting the tubes into splinter elements of a predetermined size and mass.
  • the twist projectile 1 comprises a splinter shell2 forming the projectile mantle which houses an explosive charge 3 adapted to be ignited by a fuse 4.
  • a splinter shell2 forming the projectile mantle which houses an explosive charge 3 adapted to be ignited by a fuse 4.
  • FIG. 1 is a side view of a twist projectile, partly in section.
  • FIG. 2 is a cutout of a one-layer splinter shell prior to its high pressure deformation.
  • FIG. 3 is a partial cutout of FIG. 2 after plating the tubes upon each other.-
  • outer tube 6 of deformable metal for instance extra strong aluminum or steel, with a wall thickness of, for instance, 3 mm, a layer of preformed pellet splinters 7 of ceramic (A1 0 or hard metal,
  • splinters 7 may, if desired, also have a shape differing from the shape of a sphere, for instance, may be roller-shaped. It is important in this connection that the hollow chamber 5 between the tubes 6 and 8 is uniformly filled with one layer of splinters- 7.
  • the tubes 6 and 8 are interconnected in conformity with the above described method.
  • the radial deformation may be effected in a manner known per se and, more specifically, in a shock-like manner, for instance, by explosion deformation or electromagnetically, but it may also be effected, if desired, by pressing, namely by driving a conical calibrating bolt through the inner tube 8.
  • pressing namely by driving a conical calibrating bolt through the inner tube 8.
  • the splinter shell may also consist of a plurality of layers in which instance the manufacturing process corresponds to that described above.
  • an additional inner tube is provided in addition to the tubes 6 and 8.
  • a further layer of pellet splinters 7 is filled into the tubular hollow chamber 9.
  • the pellet splinters 7 are fully pressed into the tubes 6, 8 and 10 and these tubes are prenotched in a grate-like manner.
  • FIG. 6 shows the size of the broken up splinters 11 with regard to the pellet splinters 7.
  • the method according to the present invention makes it possible to produce splinter shells which comprise two or more tubes which are plated upon each other and which by means of the enclosed pellet splinters are pre-fragmented and encase one or more layers of pellet splinters.
  • These splinter shells will then be able, when applied to twist projectiles, to withstand the shearing and centrifugal forces occurring during the firing process. Therefore, they are able directly to form the mantle of the projectile.
  • a method of making a splinter shell for use in pro- 5 jectiles which includes the steps of: preparing a first during the detonation of the explosive charge not only the pellet splinters will be freed but also the tubes will be split-up into many substantially uniform splinters of a predetermined size which with a defined piercing capability are sprayed over a limited range.
  • the present invention is, by no means, limited to the method set forth above and the splinter bodies shown in the drawing but metallic tubular body to form the outer wall of the splinter shell to be made. inserting into said first tubular body a second metallic tubular body of an outer diameter less than the inner diameter of said first tubular first and second tubular bodies partially into said annular chamber and sandwiching said splinters between said first and second tubular bodies.
