Definitions

  • the present invention relates to a device to enable the engagement of targets using a shaped charge function.
  • the use of a unit of ammunition in the form of a projectile, shell, missile, etc to engage a target by the application of a shaped charge function is already known.
  • the shaped charge is thus matched to the type of target, and there are thereby shaped charges arranged to operate at short standoff distances to the target or surface of the target, compared with a so-called jetting shaped charge function that operates at a very small standoff distance (e.g. 100 millimetres) from the surface of the target to achieve a hole in, or an impact on, the target.
  • EFP explosivesively formed projectile/penetrator
  • shaped charges with which one can begin to attack a target or surface of a target at considerably larger standoff distances (e.g.
  • the objective of the present invention is to resolve this problem, and to propose that modular charge components be used to enable one and the same ammunition unit to be matched to, or be re-configured for, the type of target in question, i.e. so that the ammunition unit can be assigned a shaped charge function at the deployment site (e.g. prior to firing, launch or weapon release) that is optimised for the target to be engaged on the occasion in question. It is thus necessary that re-configuration for the various engagement occasions can achieve optimisation for the target in question, and that it can be performed in a safe and, primarily, technically simple manner. There is even a desire that the new function with modular charges shall not unduly intrude upon the total costs in the system as such. The present invention is envisaged to resolve this problem too.
  • an ammunition unit in the form of a projectile, shell, missile, etc is arranged to operate with at least two modular charge configurations, in the first of which the ammunition unit incorporates a first modular charge or modular array that projects a first shaped charge function—such as a jetting shaped charge— while in the second configuration the first modular charge or modular array is conjoined with a second modular charge or modular array that projects a second shaped charge function such as an EFP function.
  • the ammunition unit is arranged to enable changeover from the first configuration to the second before firing, launch or release of the ammunition unit.
  • the second modular charge or modular array eliminates the shaped charge function effected by the first modular charge or modular array when the modules or arrays are arranged in conjoined mode.
  • the first modular charge incorporates a liner— forwards facing and in the form of a funnel or cone— that produces the first shaped charge function.
  • the second modular charge is thus designed with a rear section that exhibits a corresponding form to that of the said funnel or cone form.
  • the second modular charge is conjoined with the first modular charge via the said rear section which, in conjoined mode, is inserted in the funnel or cone form of the first modular charge.
  • the fit between the form of the rear section of the second modular charge and the funnel or cone form of the first modular charge is a salient feature, and exhibits an extremely precise fit in the preferred embodiment.
  • the liner that produces the second shaped charge function exhibits a lateral face that conjoins with the lateral face of the first modular charge, and the first mentioned lateral face can be considered to form a continuation or constituent part of the latter mentioned lateral face.
  • the said rear section preferably consists of or contains explosive material
  • the first modular charge preferably incorporates an essentially cylindrical container enclosing the explosive material of the first modular charge. Parts of the explosive material in the first and second modular charges conjoin with each other in the said conjoined mode.
  • the ammunition unit at delivery incorporates both modular charges or modular arrays in conjoined state. If the first charge configuration shall be used the second modular charge or modular array is thus removed.
  • the ammunition device in one embodiment is arranged with a casing or structural element that is removable when changing over between the first and second configuration modes. After the changeover it shall be possible to refit the said casing or structural element to enable the ammunition unit to be fired, launched or released. Additional variants of the present invention are disclosed in the subsequent Patent Claims and the detailed description.
  • the above proposals enable the new changeover function to be achieved without any significant financial burden to the system in its entirety.
  • the present invention exploits the insight that the explosive charge represents a relatively small value with regard to the total system, in which the functions for guidance, propulsion, actuation, etc represent the major costs.
  • the redundancy thereby achieved by the use of two different types of modular charges or modular arrays in which one modular charge or modular array is discarded in certain engagement situations is thus not a burden to the system as such.
  • Changeover can be arranged in an already known way, such as by means of screw joint(s), by means of which the casing or structural element can be removed and then refitted to achieve reliable closure.
  • the modular charges as such can also consist of conventional constructions and designs.
  • Figure 1 shows a longitudinal section of a modular charge configuration comprising first and second modular charges in conjoined mode
  • Figure 2 shows a longitudinal section of the modular charges illustrated in Figure 1, but with the second modular charge removed from the first modular charge.
  • the ammunition unit comprises, among other things, an explosive charge arrangement denoted 2.
  • the explosive charge arrangement incorporates an initiation function symbolised by 3.
  • the explosive charge arrangement comprises two modular charges, of which the first modular charge is designated 3 and the second modular charge is designated 4.
  • Modular charge 3 comprises explosive 3a and a trumpet formed, shaped charge effecting inner cone illustrated in Figure 1 by sections 3b and 3c. This inner cone 3b, 3c extends from the frontal part 3d of the modular charge 3 inwards towards the central part of the modular charge. Sections 3b, 3c show the curvature of the inner cone, and that it forms a funnel shaped space.
  • Sections 3b and 3c can exhibit other curvatures or extensions and, for example, may be essentially cone shaped.
  • the second modular charge 4 comprises a rear section 4a comprising or consisting of explosive.
  • the second modular charge also comprises a frontally concave frontal liner 4b that effects shaped charge function.
  • the rear section 4a thus exhibits a form that conjoins with walls of the space formed between 3b, 3c.
  • the fit between the outer surface 4a' of the rear section and the inner surfaces 3c' and 3b' is very precise.
  • Sections 3b, 3c are also arranged so that the first modular charge can effect a jetting shaped charge function when in a mode separated from the second modular charge.
  • the explosive charge arrangement operates with a shaped charge function effected by liner 4b.
  • the latter function in the embodiment example constitutes an EFP shaped charge function.
  • the explosive charge arrangement 2 can thus function for a large standoff A to a target 5 that is to be engaged using the shaped charge function in question, and the resultant explosively formed projectile 6 will attack the target in a concentrated zone 5a.
  • the standoff distance A may be, for example, 50 metres.
  • the second modular charge 4 has been separated from modular charge 3.
  • FIG. 1 The space in the funnel shaped part bounded by sections 3b, 3c is designated 3e.
  • Figure 2 shows the shape of the rear section 4a of modular charge 4 and its matching shape in relation to space 3e.
  • the shape of surfaces 3c' and 4a' is also illustrated.
  • modular charge 4 is not used and is discarded.
  • Modular charge 3 thus operates independently from modular charge 4, and can effect its shaped charge function which is of said jetting type. Consequently, the ammunition unit or explosive charge arrangement 2 can in this case be used to engage a target that is at standoff distance A' when ammunition unit 1 is triggered, standoff A' being relatively small— e.g. 100 millimetres— in relation to standoff A.
  • the shaped charge jet projected by modular charge 3 is designated 6'.
  • a screw joint on the casing of the device is symbolised by 7.
  • the screw joint can comprise an internal and external thread of already known type.
  • the casing or structural element la can thereby be temporarily separated from the casing or structural element lb.
  • the ammunition unit is supplied with the explosive charge arrangement in conjoined mode as illustrated in Figure 1.
  • the casing or structural element la is thus unscrewed to enable modular charge 4 to be removed, after which the casing or structural element la is screwed back onto casing or structural element lb.
  • modular charge 3 in principle can comprise a number of first modules, explosive compositions and other configurations, and that in such cases reference is made to a first modular array.
  • the second modular charge 4 can consist of more than one module, whereby such an arrangement can be envisaged as a second modular array.
  • the first modular charge can interact with a second modular array
  • the second modular charge can interact with a first modular array.
  • Figure 2 also shows that the rear section 4a exhibits a rear plane 4a" that is circular and extends at right angles to the plane of the figure illustrated. In the conjoined mode illustrated in Figure 1 this end plane 4a" butts against an inner surface 3a' in the explosive 3a of the first modular charge.
  • Liner 4b on the second modular charge 4 exhibits a lateral face 4b'.
  • This lateral face extends adjacent to an outer surface 3 f of the casing or structural element of the first modular charge.
  • Lateral face 4b' can be considered to constitute a continuation of outer surface 3f.
  • the first modular charge in principle comprises a casing that encases the explosive 3a, with the said initiating device 3' arranged at the rear of the said casing.
  • Rear section 4a consists of a self-supporting explosive charge.
