Definitions

  • the present invention is in the field military, more particularly in that of explosive ordnance, projectiles, bombs, various devices for example, with controlled fragmentation (also called “predetermined” or “prepared”), in particular intended for anti-runway, anti-bunker or anti-vehicle operations (ships, tanks, tanks, etc.).
  • the contact areas between the casing and the sleeve are therefore separated by cavities corresponding to the volume of indentations.
  • Patent FR 2 685 077 describes an element of ammunition explosive with controlled fragmentation allowing optimize the size of the chips produced by its fire depending on the target attacked.
  • the explosive charge is contained in a metal envelope consisting of 2 walls concentric, ferrule-shaped, separated by a clearance allowing them to be made mobile relative to the other according to a movement of rotation and / or translation, each wall being intended to be fragmented to produce shards whose mass individual is predetermined.
  • the relative mobility of the 2 walls in coincidence allows adjustment and programming, manual or automatic, the size of the flakes.
  • Patent FR 2 433 731 describes an element of ammunition explosive with controlled fragmentation comprising a thin-walled lining located between the envelope metal and the explosive charge and comprising indentations which are ribs directed towards the interior in the shape of a roof.
  • the filling, made up by a thin sheath, provides an interior coating, total or partial, of the envelope.
  • the envelope is internally smooth and is covered with a metal trim or plastic material comprising ribs directed towards the interior in the shape of a roof.
  • the trim is made of plastic, to make the explosive ordnance element, cover it, during the manufacture of the explosive charge by molding, the internal parts of the mold by a sheet plastic coated by front heating introduction of the explosive in a liquid or pasty state.
  • Closing the mold provided with projections causes the formation of roof-shaped ribs.
  • This load and its trim must then be introduced in a metallic envelope with dimensions suitable for making the ammunition element.
  • the object of the present invention is in particular to propose a much simpler and more economical process.
  • the proposed solution consists in carrying out prior, in particular using industrial techniques by simple and inexpensive molding well known from a person skilled in the art, a rigid enclosure-shaped sleeve provided with a single opening and provided with indentations directed inward, insert this sleeve into the metal structure of the ammunition and then proceed then to the classic casting and solidification of an explosive composition.
  • the present invention therefore relates to a new method of manufacturing a munition element explosive with controlled fragmentation comprising a solid explosive charge contained in an enclosure metallic whose inner wall is coated with a sleeve externally provided with indentations, it is say interior notches, grooves. Wall inside of the envelope and the outside surface of the sleeve are therefore in contact through protruding areas separated by voids corresponding to the volume of indentations.
  • the method according to the invention is characterized in that that we realize first of all, in general and preferably by molding, a rigid plastic sleeve or elastomeric, externally provided with indentations, and having an enclosure shape provided with a single opening, for example a form of case, bottle, warhead, cup or sock. Then we introduce the sleeve in a metal envelope comprising a opening and whose shape and dimensions are such that the sleeve can coat the inner wall of the envelope, the sleeve being introduced through the opening of the envelope the bottom first, that is to say so such that the opening of the sleeve is located opposite opening the envelope to make it accessible inside the sleeve through the opening of the envelope.
  • composition is poured into the sleeve explosive pasty or liquid, then solidify the composition.
  • plastic we conventionally mean any synthetic material based on the use of macromolecules and capable of being shaped or molded, usually hot and pressurized.
  • elastomeric material we conventionally mean any polymeric material, natural or synthetic, having elastic properties and which can serve as rubber.
  • the element of Explosive ordnance has an axis of symmetry. In a way preferred, it presents, in whole or in part, a cylindrical or ogival shape.
  • the bottom can be flat, rounded, or of any shape. So that the sleeve can internally coat the envelope, when the munition element has a cylindrical shape, the inner diameter of the envelope is equal to the diameter outside of the sleeve and when the ammunition element has an ogival shape, the dimensions of the ogives delimited by the inner wall of the envelope and by the outer wall of the sleeve are identical.
  • the thickness of the wall of the sleeve is preferably constant or substantially constant, especially in the peripheral zone.
  • the thickness of the bottom wall of the sleeve i.e. the part of the sleeve opposite to its single opening can, for example, be slightly superior, in particular due to the technique of aforementioned blowing.
  • the thickness of the sleeve wall can be any. It is however preferably significantly lower than that of the metal envelope, for example between 5% and 25% of the thickness of the envelope, preferably about 10%.
  • the indentations can have any form, but are preferably dihedral, roof-shaped, the dihedral edge being located towards the interior of the muff.
  • Dihedrons may have an opening angular in multi slope, for example in double slope, with respect to their plane of symmetry.
  • the indentations, dihedral or no are identical, and particularly preferred, when the sleeve has a shape cylindrical, they are distributed in the same crowns height with identical number of indentations identical, the indentations being regularly distributed on each crown and located alternately with the indentations of the upper crown and those of the lower crown.
  • each indentation is thus located between two protruding areas not indented from the two crowns adjacent, and projecting surfaces in contact with the envelope, are identical, regularly spaced, in alternating from one crown to another, and represent approximately a chessboard drawing.
  • the bottom of the sleeve is generally smooth, devoid of indentations. This is also the case for the part of the sleeve located near the opening.
  • peripheral zone has indentations.
  • the two sides which can for example be approximately flat and parallel, constituting the bottom and the area in which the opening is located lack them.
  • edges of the sleeve connecting the peripheral zone and the two flat faces can be rounded.
  • the inner and outer walls of the envelope metallic are not weakened, i.e. that they are appreciably smooth, devoid of veins and / or grooves, crack initiators whose network predetermines future fragments.
  • the present invention is therefore particularly interesting to implement in these situations.
  • the plastic or elastomeric material constituting the rigid enclosure-shaped sleeve with a single opening is chosen from the group made up of polyalkylenes, natural elastomers and synthetic elastomers, preferably polyethylene low or high density.
  • the sleeve can be manufactured by any technique of molding or extrusion, but we prefer to use the extrusion blow molding technique, well known to plastics manufacturers, widely used for manufacturing plastic bottles, which is simple, little expensive and allows high rates.
  • the sleeve must be rigid enough to withstand the pressure of explosive compositions pasty or liquid when these are introduced.
  • the sleeve is made of polyethylene, and so more general when it has flexibility and sufficient elasticity to be compressed without deterioration, we can introduce, by opening the envelope, a sleeve whose size is greater than envelope opening template.
  • the sleeve resumes its shape and its original size and coated internally the envelope.
  • the flowable explosive composition consists of a binder organic polymerizable charged whose charge contains at least one organic nitro explosive, and we solidify the composition by polymerization of the binder. We obtain thus a charge of the composite explosive type (Cast explosive plastic bonded).
  • pouring the explosive into the sleeve can be performed at atmospheric pressure or by injection under pressure, or by gravity under empty.
  • organic nitro explosives we may include hexogen, octogen, pentrite, 5-oxo 3-nitro 1,2,4-triazole (ONTA), and mixtures of minus two of these compounds.
  • a polymerizable organic binder can quote those allowing obtaining, after polymerization, for example by heating, of a matrix solid polymer filled with polyurethane type or polyester, possibly having groups energetic such as fluorinated, nitrated groups and / or azidae.
  • Polyurethane matrices are generally obtained by reaction of a prepolymer with hydroxyl endings with a polyisocyanate.
  • terminated prepolymers hydroxyls there may be mentioned those whose skeleton is a polyisobutylene, a polybutadiene, a polyether, a polyester, a polysiloxane. Preferably a polybutadiene with hydroxyl endings.
  • polyisocyanates examples include isophorone diisocyanate (IPDI), toluene diisocyanate (TDI), dicyclohexylmethylene diisocyanate (Hylene W), hexamethylene diisocyanate (HMDI), biuret trihexane isocyanate (BTHI), and their mixtures.

  • TNT trinitrotoluene
  • Explosive molten compositions such as moreover in general, composite explosives aforementioned plastic binder used by casting, are well known to those skilled in the art.
  • the solid explosive charge is a bi-composition charge comprising a central coated composition by a peripheral composition.
  • Bi-composition explosive charges and their processes for obtaining from explosive compositions flowable, pasty or liquid, are well known from the skilled person.
  • peripheral composition is less sensitive to the shock wave as the central composition, like those described for example in patents FR 2,668 146 and FR 2,678,262.
  • a removable pin is introduced in the sleeve then we sink, in the space between the pin and the inner wall of the sleeve, the composition liquid or pasty device. After solidification, we remove the spindle then we sink, in the space freed by the spindle, the liquid central composition or pasty which is then solidified.

  • the dihedral indentations are located alternately with the indentations of the upper crown and those of the lower crown.
  • Each indentation is thus located between two zones in non-indented projection of the two adjacent crowns and projecting surfaces in contact with the envelope steel are identical, regularly spaced, in alternating from one crown to another, and represent approximately a checkerboard design approximately rectangular.
  • a rounding of 12mm radius connects the cylindrical part and the bottom. Another rounding of the same radius connects this same cylindrical part and the face, opposite the bottom, which includes an axial circular opening of diameter 90mm.
