Definitions

  • the technical field of the invention is that of explosive materials with reduced vulnerability as well as methods of casting such explosive materials.
  • Explosive materials with reduced vulnerability become essential for the design of ammunition. In fact, they make it possible to produce munitions which resist without detonating to aggressions such as bullet impacts or fires.
  • Composite explosives use crosslinkable organic polymers. They are implemented by pouring the explosive mixed with the organic binder and solidification is obtained by the polymerization of the charge.
  • the fusible explosives consist of a material combining, on the one hand a solid phase comprising at least one solid explosive with reduced vulnerability, and on the other hand a fusable phase which comprises at least one fusible explosive, at least one phlegmatizer and at least an emulsifier of the phlegmatizer in the fusible explosive.
  • the solid explosive with reduced vulnerability is most often constituted by Oxinitrotriazole (or ONTA), but it is also possible to use triaminotrinitrobenzene (TATB) or Nitroguanidine (NGu).
  • Oxinitrotriazole or ONTA
  • TATB triaminotrinitrobenzene
  • NGu Nitroguanidine
  • the fusible explosive is preferably a nitrated aromatic (such as trinitrotoluene or TNT, or 2,4,6-Trinitro-N-Methyl Aniline or TNMA), and the phlegmatizer is most often constituted by a wax.
  • a nitrated aromatic such as trinitrotoluene or TNT, or 2,4,6-Trinitro-N-Methyl Aniline or TNMA
  • the patent EP814069 thus describes various types of fusible explosives with reduced vulnerability and their preparation processes.
  • the solid phase is then introduced into the liquid phase, then the casting is carried out in the ammunition body and finally the cooling leading to the solidification of the explosive.
  • the steps to be carried out use a fusable phase and a solid phase which must be mixed with care so as to ensure a homogeneous composition.
  • This mixture is all the more delicate since the fusible insensitive explosives use a relatively high proportion of phlegmatizer (wax) (greater than or equal to 3% by mass).
  • phlegmatizer greater than or equal to 3% by mass.
  • the hot mixing of the fusible explosive with the phlegmatizer which must ensure its coating therefore requires the use of an emulsifier as well as the vigorous mixing of these elements to ensure the creation of a homogeneous emulsion.
  • the temperature must also be controlled.
  • Such a process is much more complex than the methods of casting conventional fusible explosives in which it is generally sufficient to mix in a casting tank the fusible explosive (TNT) and the solid explosive (hexogen) before proceeding with the casting.
  • TNT fusible explosive
  • hexogen solid explosive
  • granules of a composition combining very high explosives are produced on the one hand.
  • energetic (HMX, RDX) with wax and aluminum powder and on the other hand other granules of a composition associating TNT and an emulsifier.
  • These two types of granules are then mixed in the desired proportions to achieve the final explosive charge.
  • Such a process is complex to implement because it requires the production of two types of granules which will be mixed subsequently.
  • This process also requires a mixture of the starting compounds in water which requires the use of a particular aluminum powder which is treated to resist water.
  • this process does not describe an explosive composition using an explosive with reduced vulnerability, such as ONTA.
  • the object of the invention is to propose a method for casting an explosive material with reduced vulnerability, a method which makes it possible to simplify the casting operations.
  • This process proposes the implementation of a prefabricated explosive material and ready for use. It can thus be easily implemented by manufacturers equipped with conventional casting equipment.
  • the subject of the invention is a process for casting an explosive material with reduced vulnerability which combines, on the one hand a solid phase comprising at least one solid explosive with reduced vulnerability, and on the other hand a fusible phase which comprises at at least one fusible explosive, at least one phlegmatizer and at least one emulsifier of the phlegmatizer in the fusable explosive, remarkable process in that the explosive material with reduced vulnerability in the solid state is placed in a melting tank equipped heating means and provided with stirring means, the explosive material with reduced vulnerability being placed in the tank in the form of prefabricated grains with a smaller dimension of 1 mm to 4 mm, these grains having been manufactured beforehand during mixing, casting and then solidification and shaping steps, the prefabricated grains of explosive material with reduced vulnerability having larger dimensions ior to the largest initial particle size of the solid phase materials they contain.
  • the casting is carried out under vacuum.
  • the fusable phase essentially comprises trinitrotoluene or 2,4,6-Trinitro-N-Methyl Aniline.
  • the solid phase essentially comprises oxinitrotriazole, triaminotrinitrobenzene or Nitroguanidine.
  • the heating tank containing the prefabricated grains is brought to a temperature of 10% to 35% higher than the melting temperature of the fusible explosive and with stirring so as to ensure the setting as an emulsion of the various materials constituting the mixture.
  • the fusible explosive is cooled to a temperature slightly (from 2% to 7%) higher than the melting temperature of the fusible explosive, before proceeding with the casting.
  • the invention also aims to provide a fusible explosive material with reduced vulnerability, prefabricated and ready to use, therefore with simplified implementation.
  • the fusible explosive material according to the invention is thus remarkable in that it is fusable and is in the form of solid grains (23) composed of a mixture associating, on the one hand, a solid phase comprising at least one solid explosive with reduced vulnerability, and on the other hand a fusible phase which comprises at least one fusible explosive, at least one phlegmatizer and at least one emulsifier of the phlegmatizer in the fusible explosive, the solid grains of explosive material with reduced vulnerability having a smaller dimensions from 1 mm to 4 mm and having been manufactured beforehand during mixing, casting and then solidification and shaping steps, the grains of explosive material with reduced vulnerability having moreover dimensions greater than the largest particle size of the materials of the solid phase they contain.
  • the grains have the form of flakes or scales, therefore have a substantially planar shape having a thickness less than the dimensions of their planar shape, the thickness being greater than or equal to 1 mm.
  • the grains have a generally cylindrical or spherical shape whose smallest dimension is greater than or equal to 1 mm.
  • the fusable phase of the explosive material essentially comprises trinitrotoluene or 2,4,6-Trinitro-N-Methyl Aniline.
  • the solid phase essentially comprises oxinitrotriazole or triaminotrinitrobenzene or nitroguanidine.
  • the figure 1 shows a casting installation 1 which is intended to ensure the explosive loading of several ammunition bodies 2, here artillery shells arranged on a transportable pallet 3.
  • Each shell 2 carries a riser 2a which aims to facilitate the casting and which allows to leave a block of explosive outside the shell body, block on which occur the deformations and shrinkage related to cooling. This block is detached from the shell after cooling.
  • the installation 1 mainly comprises a pouring tank 4 which is arranged above one of the ammunition bodies 2. Concretely the tank 4 will be fixed on a support not shown and the ammunition body 2 will be positioned by moving the pallet 3.
  • the tank 4 is produced in a conventional manner from a corrosion-resistant material, for example stainless steel. It has a cover 4a which can be tilted to close the tank in a sealed manner. It contains an agitator means 5, which is shown very schematically here.
  • This means is a planetary type mixer and it comprises, in a well known manner, rotary blades driven by a motor (not shown). The blades will have dimensions allowing them to mix the whole mixture.
  • the tank 4 comprises a nozzle 4b closed by a pouring valve 6, the opening and closing of which are controlled by a control means 7, for example a programmable automaton.
  • the tank 4 is connected to a first heating means 8a, such as a boiler.
  • a heat transfer fluid is led from the boiler 8a to the tank by a pipe 9 on which a thermostatic valve 10 is placed.
  • the tank has a double wall inside which the heat transfer fluid can circulate.
  • the nozzle 4b is connected to a second boiler 8b by a thermostatic valve 11. This ensures uniformity of the temperature of the explosive material both inside the tank 4 and at the nozzle 4b.
  • the use of two separate boilers ensures independent heating for the tank 4 and the nozzle 4b.
  • the temperature will be chosen according to the melting characteristics of the material to be cast. Generally for fusible explosive materials, the temperature is between 75 ° C and 110 ° C.
  • thermostatic valves 10 and 11 can advantageously be controlled in temperature by the automaton 7 (the connections with the PLC are not shown for clarity of the figure). For this, temperature probes will be placed at the level of the various pipes as well as of the tank and the nozzle.
  • a pouring funnel 18 is fixed at a bottom of the tank, that is to say here at the nozzle 4b. It is intended to allow the explosive to be poured under vacuum into the munition body 2. In fact, fusible explosives with reduced vulnerability are generally quite viscous. Vacuum casting makes it easier (and faster) to load ammunition bodies 2.
  • This funnel 18 is the subject of the patent application FR2923005 filed October 29, 2007 which can be referred to for more details.
  • Vacuum means 17 (such as a vacuum pump) are provided. These means make it possible to create a vacuum at the level of the tank 4 and also at the level of the pouring funnel 18, of the nozzle 4b and of the ammunition body 2 on which the funnel 18 is positioned.
  • the vacuum pump 17 is thus connected to the tank 4 by a line 21 on which a first stop valve 22 is placed.
  • the vacuum pump 17 is also connected to the funnel 18 (more precisely to the nozzle 4b located above the funnel) by a line 19 on which a second stopcock 20 is placed.
  • each tap 20, 22 as well as the control of the pouring valve 6 are provided by the programmable controller 7.
  • this installation 1 is conventional. It can be used to charge ammunition with a conventional explosive, for example a composition B (combining hexogen and Trinitrotoluene in the respective mass proportions of 60% and 40%).
  • a conventional explosive for example a composition B (combining hexogen and Trinitrotoluene in the respective mass proportions of 60% and 40%).
  • vacuum casting means makes it possible to evacuate the bubbles in the loading carried out. These means also make it easier to load a viscous explosive.
  • This installation can also be used without other modifications to load ammunition bodies 2 with a reduced vulnerability explosive.
  • This material will combine, on the one hand a solid phase comprising at least one solid explosive with reduced vulnerability (for example oxinitrotriazole or ONTA), and on the other hand a fusable phase which comprises at least one fusible explosive (for example trinitrotoluene or TNT), at least one phlegmatizer (such as a wax) and at least one emulsifier of the phlegmatizer in the fusible explosive.
  • a solid phase comprising at least one solid explosive with reduced vulnerability (for example oxinitrotriazole or ONTA)
  • a fusable phase which comprises at least one fusible explosive (for example trinitrotoluene or TNT), at least one phlegmatizer (such as a wax) and at least one emulsifier of the phlegmatizer in the fusible explosive.
  • the fusable explosive is a nitrated aromatic such as 2,4,6 Trinitro-N-Methyl aniline (TNMA), 2,4,6-Trinitro-3-methylphenol, 3-amino-Trinitrotoluene , 2,4,6-Trinitro-aniline, 1,3,8-Trinitronaphthalene and its mixture of isomers fusible at 115 ° C.

  • 3-amino-Trinitrotoluene 2,4,6-Trinitro-aniline
  • 1,3,8-Trinitronaphthalene 1,3,8-Trinitronaphthalene
  • Dinitroanisole which is a fusible explosive with reduced toxicity.
  • This explosive is described in particular by the patent application US2005230019 . It is most often associated with processing additives chosen from the group of N-alkylnitroanilines and N-arylnitroanilines.
  • the explosive with reduced vulnerability can be chosen from: oxinitrotriazol (ONTA), triaminotrinitrobenzene (TATB), nitroguanidine (NGu).
  • ONTA oxinitrotriazol
  • TATB triaminotrinitrobenzene
  • NGu nitroguanidine
  • the phlegmatizer will be for example a polyolefin wax and the emulsifier a vinyl copolymer pyrrolidone.
  • the phlegmatizer will be chosen with a melting temperature substantially equal to that of the fusable explosive (within plus or minus 2 ° C).
  • the uniformly distributed phlegmatizer has a function contributing to the desensitization of the material by increasing its homogeneity which makes it less sensitive to heating.
  • the emulsifier is chosen so as to ensure the best interface between the molten explosive and the phlegmatizer.
  • the phlegmatizer makes it possible both to promote the dispersion of the pulverulent constituents and to stabilize the emulsion obtained.
  • the phlegmatizing rate is also generally less than 12% because too high a wax rate penalizes the detonating characteristics of the material.
  • the explosive material may also include aluminum powder (which makes it possible to increase the resistance of the material to heating while increasing the blast effect during detonation).
  • the grains of material according to the invention will have a substantially homogeneous chemical composition, and they will be manufactured beforehand during stages of mixing, casting, then solidification and shaping.
  • homogeneous chemical composition is understood to mean the fact that this composition is substantially identical from one grain to another.
  • composition B It suffices to put these grains of composition B in a tank brought to the appropriate temperature to obtain a new fusion allowing the loading of the ammunition.
  • composition B is a simple composition combining TNT (fusible) and hexogenic (solid) with sometimes a small part of wax (of the order of 1% by mass) to improve the mechanical strength of the explosive after cooling.
  • an explosive material incorporates a solidified emulsion of a fusible explosive and a phlegmatizer and it also incorporates granular materials having different particle sizes (ONTA and Aluminum in particular).
  • the casting was carried out in a conventional ammunition case.
  • Chips of the explosive material were then produced by machining the charge obtained.
  • thin plates of the explosive material were produced by roughly fragmenting the solidified bottom of the vessel.
  • the resistance over time of the material obtained as well as its viscosity are of the same order as those of the original material and are sufficient to allow filling a body of ammunition then cooling it to solidify the material while keeping its homogeneity (no phase separations).
  • a necessary condition for it to be possible to reuse such an already fused explosive material is therefore that the complete structure of the material is found unmodified inside each prefabricated grain.
  • the smallest dimension of each prefabricated grain is greater than the largest particle size of the materials of the solid phase that they contain.
  • the largest particle size is that of explosive material with reduced vulnerability (such as ONTA).
  • each solid explosive grain (ONTA for example) is coated with a solidified and homogeneous emulsion of the fusible explosive (TNT) with its phlegmatizer.
  • the figures 2a to 2d show different shapes which can be adopted for the grains 23 of the fusible explosive material: fine regular lamellae ( figure 2a ), spheres or balls ( figure 2b ), cylindrical granules ( figure 2c ), irregular thin scales ( figure 2d ).

  • This tank does not supply ammunition bodies here but it deposits the fusible explosive material 12 on a conveyor belt 13 driven by drums 14a, 14b.
  • the treadmill 13 has lateral cheeks 15a, 15b which may be made of rubber (therefore deformable) or else in the form of metal tongues integral with the carpet 13 and overlapping two by two to allow the passage of the drums 14a, 14b.
  • the cheeks 15a, 15b define the volume on which the explosive 12 is contained and prevent this material from overflowing outside the mat 13.
  • a scraper 16 makes it possible to give the explosive layer 12 a given thickness.
  • the vertical position of the scraper 16 is adjustable (by means not shown).
  • the conveyor belt 13 circulates in part in a thermostatically controlled box 24 which makes it possible to ensure controlled cooling of the material 12.

  • this material allows, after remelting, to make loadings with reduced vulnerability. It will be noted that it will also be possible to reuse the solidified tank bottoms as well as the ammunition enhancements during subsequent pourings. It will be enough to roughly break these explosive blocks to incorporate them into a new pour with the prefabricated grains.
