Definitions

  • the present invention relates to a tandem charge for a missile.
  • tandem charges contain a pre-charge and a main charge, which is used to combat hard target structures such as bunkers or the like.
  • the pre-charge which is usually provided as a pre-hollow charge, initially creates a deep crater in the target material, into which the main charge penetrates. This "pre-drilling" by means of the pre-hollow charge significantly increases the effective power of the main charge on the one hand and reduces the risk of slipping from the target at inclined angles of incidence ("ricochet" effect) on the other hand.
  • Such a pre-shaped charge is designed to be correspondingly large.
  • the DE 36 03 620 C1 describes a tandem shaped charge.
  • a fixed protective hood made of steel is proposed between a pre-hollow charge and a main hollow charge, which completely surrounds the main hollow charge and thus provides, on the one hand, a free space for spike formation and, on the other hand, protection from plumes and fragments as well as the shock wave in the event of detonation of the pre-hollow charge.
  • the DE 36 01 051 C1 describes a tandem charge with a pre-hollow charge and a main hollow charge, a vapor shield being provided between the pre-hollow charge and the main hollow charge.
  • a sleeve which can be displaced with respect to the main hollow charge is arranged on the vapor shield, the ignition device of the main hollow charge being triggered by the sleeve striking it.
  • the EP 2 327 952 A1 and the DE 41 26 793 C1 describe further tandem loads.
  • the present invention is based on the object of providing a tandem charge with improved shock properties.
  • this object is achieved by a tandem charge for a missile with the features of claim 1 or 8.
  • a tandem charge for a missile.
  • the tandem charge comprises a pre-charge, in particular a pre-shaped charge, and a main charge which has a shell with a tip aligned with the pre-charge.
  • a cap is provided which is placed on the tip and is designed to repel shock waves that arise when the subpoena detonates.
  • the idea on which the present invention is based consists in providing the tip of a shell of a main charge with an additional shock-repellent cap.
  • the properties of the tip can be freely modified without having to take into account the boundary conditions that apply to the design of the tip.
  • a shape or geometry and a material selection of the cap for shock repellency can be selected in an optimized manner.
  • coupling of the shock wave into the envelope is effectively reduced. This greatly reduces the load on components of the main charge that are arranged within the shell, in particular a safety device and / or an ignition system that is usually arranged on a rear side, as well as mechanical components such as threads and the like.
  • the main charge can have a wide variety of configurations.
  • the present invention is applicable to both main charged cargoes with a protective hood or shell as well as for penetrator main charges with a penetrator shell.
  • the cap is specially designed to accommodate the respective tip of a sheath, in particular with a recess which corresponds to the negative shape of the tip.
  • the solution according to the invention of a cap applied to the tip of the shell of the main charge advantageously requires only a small amount of space and does not require any change in the main charge per se.
  • the main charge is therefore not subject to any restrictions on the power side or in terms of functionality.
  • the cap according to the invention can also be retrofitted to existing tandem loads. In an existing system, this only needs to be placed on the tip of the shell of the main charge, which is made possible in a simple manner by the small installation space and without the need for other changes. Of course, a suitable fastening of the cap can be provided as required.
  • the main charge is designed as a penetrator charge and the shell is provided as a penetrator shell with a tip correspondingly shaped as a penetrator tip. Since the penetration performance of a penetrator depends essentially on the shape of the penetrator tip, this generally cannot be subjected to any geometric changes in order to repel shock. With the solution according to the invention, this can be counteracted in that the penetrator tip remains unchanged and yet an optimized one thanks to the cap Shock rejection in the event of detonation of the summons is enabled. This means that the shock wave can only get into the envelope to a greatly reduced extent.
  • the tip is bi-conical, the cap covering at least one front cone of the tip.
  • the cap is designed in two parts with an inner and an outer cap, the front cone being covered with the inner cap and the rear cone together with the inner cap being covered with the outer cap.
  • a cap that is specially designed for bi-conical penetrator tips and yet easy to manufacture and apply is advantageously provided.
  • different materials can be provided for the inner and the outer cap, in particular a plastic for the inner cap and copper or a heavy metal, for example tungsten heavy metal, for the outer cap, in order to achieve additional reflection of the shock wave at the material transition.
  • the cap has a pointed end with a shape that tapers at a more acute angle than an angle of the tip.
  • a significantly smaller part of an incident shock wave in particular corresponding to the product of the incident shock wave with the sine of the angle of incidence, is transmitted into the envelope than in the case of an obtuse angle, the sine of which would be significantly larger.
  • the remainder of the shock wave that is not transmitted into the shell then slides along the cap or shell without transmission.
  • the cap has a different material than the shell.
  • Different materials usually have different shock wave impedances. This is especially true for materials with different densities, because the shock wave impedance depends, among other things, on the density of a material. At material transitions, seams or the like, at which there is a density jump in the case of different materials, there are thus also impedance jumps. Such jumps in impedance lead to partial transmission and partial reflection of the shock wave.
  • Appropriate selection of the material for the cap, with the largest possible impedance difference between the cap and the shell, in particular with a higher density and shock wave impedance than the tip can therefore additionally reduce the shock wave transmission into the shell.
  • the cap contains a heavy metal.
  • it can be a tungsten heavy metal.
  • a high density and thus a shock wave impedance that is high compared to the usually metallic shell is provided, which advantageously creates an impedance jump at the material transition and thus contributes to reducing the transmission of a shock wave into the shell.
  • the cap has a multilayer structure made of materials of different shock wave impedance. In this way, the effect of only partial transmission and partial reflection at material transitions can already be used several times within the cap, so that an additional reduction in the transmission of a shock wave into the shell is made possible.
  • the multilayer structure contains at least one plastic layer and at least one metal layer, in particular a copper or heavy metal layer. Because of the very different densities, there is a high impedance difference between the plastic layer and the metal layer. Compared to plastic, copper already has a relatively high impedance (density of 8.9 g / cm 3 ). In the case of a heavy metal, however, this difference can be increased significantly, for example by using tungsten heavy metal (density of up to approx. 18 g / cm 3 ). This increases the impedance difference and thereby the degree of reflection.
  • the cap is designed in such a way that it breaks when a shock wave generated when the subpoena detonates is rejected, so that the tip of the casing is exposed.
  • This can be achieved, for example, by using a brittle material and / or one or more predetermined breaking points in the material.
  • the tip of the envelope is released.
  • this is particularly advantageous since the penetration performance, which is greatly increased per se by means of the precharge, is thus not impaired by the cap.
  • the cap contains a sintered material, in particular sintered heavy metal.
  • a sintered material in particular sintered heavy metal.
  • This can be provided both in the case of a solid cap and in the case of a multilayer structure of the cap.
  • This is preferably a tungsten heavy metal, which is designed to be so brittle that it is broken down in the event of a load occurring when the shock wave is rejected.
  • the material properties can be adjusted in the sintering process.
  • the material can be designed to be brittle in a targeted manner by setting the sinter matrix proportions and sintering times.
  • the proportion of tungsten material can be more than 90%, in particular in a range from 90% to 98%, and only the remainder can be provided as a matrix, for example containing nickel and / or iron.
  • suitable sintering times can range from 4 to 8 hours lie.
  • deviations are possible depending on the other conditions used, such as pressure and temperature, among others.
  • the recess is designed to taper conically in accordance with a shape of the tip, the tapering end of the second side tapering at an angle that is more acute than the recess.
  • the cap provides a geometry that tapers to a point compared to the tip of the shell, so that a portion of the shock wave transmitted into the shell is already reduced purely by the geometric configuration of the cap.
  • the cap contains a heavy metal.
  • it can be a tungsten heavy metal.
  • the cap has a multilayer structure made of materials of different shock wave impedance.
  • plastics come into consideration as the material of low shock wave impedance and, for example, copper or heavy metals, in particular tungsten heavy metal, as material of high shock wave impedance.
  • a multiplicity of impedance jumps is provided within the cap, the reflected portion of the shock wave increasing and the portion transmitted into the envelope advantageously further decreasing.
  • the cap is designed in such a way that it breaks when a shock wave generated when a subpoena detonates is rejected.
  • the tip of a sheath in particular in the case of a Penetrator sheath, to be released after rejection. In this way, an optimal penetrator performance is advantageously guaranteed.
  • the cap contains a sintered material which is designed to be so brittle that it is broken down in the event of a load occurring when the shock wave is rejected.
  • the material properties can advantageously be set in the sintering process.
  • it can be a sintered heavy metal, preferably a tungsten heavy metal.
  • the material can thus advantageously be designed to be brittle in a targeted manner by setting the sinter matrix proportions and sintering times. Furthermore, a high density and thus a high shock wave impedance are thus provided.
  • Fig. 1 shows a schematic representation of a tandem charge 1 according to the invention.
  • a missile 10 is shown here symbolized only in sections and can be implemented in a variety of ways. For example, it can be a guided missile of the most varied of types.
  • the tandem charge 1 has a pre-charge 2 and a main charge 3.
  • the only schematically shown pre-charge 2 is in particular a pre-hollow charge, but other types of pre-charge are also conceivable.
  • the main charge 3, shown only in sections and schematically, can be, for example, a main hollow charge or a penetrator main charge, but other types of main charge are also conceivable.
  • the main charge 3 has a casing 4 with a tip 5 aligned with the pre-charge 2.
  • a cap 6 is placed on the tip 5 and is designed to repel shock waves that occur when the summons 2 detonates.
  • Fig. 2 shows a schematic individual representation of a shock-repellent cap 6.
  • the cap 6 has a first side which is formed with a recess 8 for receiving a tip 5 of a casing 4 of a main charge 3. On a second side, the cap 6 has a tapered end 7 for repelling shock waves.
  • the cap 6 serves to reduce the transmission of shock waves into the shell 4 of the main charge 3, which occur when the precharge 2 detonates. In this way, a significantly smaller proportion of the shock waves are transmitted into the shell 4. Thus, a load on components arranged within the casing 4, in particular a safety device and / or an ignition system and mechanical components such as threads or the like of the main charge 3, is greatly reduced.
  • Different configurations of the cap 6 can be provided for shock wave repulsion, in particular different geometrical configurations and different material configurations, which in relation to FIG Figures 5 to 10 will be discussed in more detail.

  • a compression element 101 for compressing the explosive is provided between the closure 109 and the explosive of the penetrator charge 103.
  • the pre-shaped charge 102 in this example is designed in a conventional manner with a shaped charge cone 110 and an explosive and ignition system 108 arranged behind it, as is known per se to the person skilled in the art and does not require any further explanation.
  • Fig. 4 shows a schematic representation of the transmission of shock waves 107 into the envelope when the pre-hollow charge 102 detonates.
  • shock waves 107 are coupled into the penetrator casing 104 via the air. These shock waves 107 run further back in the penetrator sheath 104, are reflected there and hit the thread 106 and the closure 109 or the safety device SE and the ignition system ZS several times.
  • the nose shape of the sheath 4, which contains the tip 5, has a strong influence on the shock wave transmission into the sheath material.
  • the shape of the nose also significantly influences the penetration capacity of a main penetrator charge 103, so that the shape of the tip 5 can hardly be changed, at least for main penetrator charges.
  • Fig. 5 shows a schematic representation of a section of a main charge 3 according to an embodiment.
  • the conflict of objectives of the nose shape of the main charge 3 can be resolved.
  • the cap 6 enables measures for shock wave damping in a novel way, which can include both geometric measures and measures in the combination of materials.
  • a cap 6, which is applied to the tip 5 of the casing 4 of the main charge 3 and which repels the shock waves from the casing 4 to a large extent, is therefore provided.
  • This inventive solution of a tandem charge or a shock-repellent cap 6 is not limited to penetrator main charges, but can be used for various types of main charges 3, for example also for main hollow charges with a protective cover.
  • Fig. 6 shows a detailed representation of the geometric measures achieved by the cap 6 for shock rejection.

  • the tip 5 is also designed bi-conically.
  • the cap 6 is formed in two parts here and has an inner cap 6A and an outer cap 6B.

  • other forms of the tip 5 and other forms of the cap 6, in particular adapted to different types of tips of a penetrator or a different type of main charge 3, are conceivable.
  • shock wave transmission into the shell 4 can thus optionally or in addition to geometric measures be further reduced.
  • the cap 6 therefore preferably has a material that differs from the sheath 4.
  • the cap can be a material with a higher density and have a higher shock wave impedance.
  • the cap 6 can contain copper or a heavy metal for this purpose.
  • WSM tungsten heavy metal
  • tungsten heavy metal has proven to be even more advantageous.
  • tungsten heavy metals have a much higher density than copper (density of 8.9 g / cm 3 ) of up to approx. 18 g / cm 3 .
  • they have another advantage that consists in the fact that tungsten heavy metal is produced by sintering. The sintering process can be used to set material properties that can be adapted to a large extent to the required conditions.
