Definitions

  • the invention relates to an explosive charge, which has an explosive material consisting of three-dimensional form and which unfolds by way of explosion a spatially anisotropic pressure effect in at least one main direction of action, in which the pressure effect is greater than in other directions.
  • a detonation of explosive produces a strong pressure effect in the air, depending on the quantity, arrangement and composition of the explosive Surroundings of the place where the detonation occurs.
  • the pressure effect is usually based on a chemical reaction of the explosive to gaseous reaction products, the so-called windrows, which spread with high temperatures and densities due to the large pressure difference to the environment at high speeds.
  • the expanding swaths also create a propagating shock wave in the surrounding air that typically precedes the reaction products.
  • the occurrence of the pressure effect can be illustrated by the example of the detonation of a spherical explosive, a so-called ball charge.
  • a spherical explosive a so-called ball charge.
  • an air blast wave as well as the swaths, starting from the center of the detonation, spread evenly in all spatial directions, i. isotropic, wherein the temperature of the reaction products, i. the windrow decreases with increasing distance from the center.
  • the pressure effect of the swaths decreases sharply with increasing distance from the location of the detonation.
  • FIG. 2 a and b show a diagrammatic representation of two snapshots relating to the pressure propagation during the explosion of a ball charge.
  • the diagrams each show the spatial pressure profile at the time of the snapshot.
  • FIG. 2a shows the pressure effect in the so-called near field, ie in a distance range from the explosion of only a few charge radii at an early stage, where a large contribution of the swath flow is given to the pressure effect.
  • the total pressure effect in the in Fig. 2a The discussed distances of 1-2 charge radii are very predominantly caused by the high flow pressure of the explosion swaths at the beginning of the swath expansion.
  • the pressure effect thus decreases rapidly with unformed charges with the distance. If one endeavors to make an increase in the range of the pressure effect, an increase in the quantity of explosive is not a suitable measure. In order, for example, to achieve the same maximum pressure 10 times over, an increase in the explosive mass by a factor of 1000 is necessary according to the scaling laws.
  • So-called shaped charges provide a one-sided sheathing of a rotationally symmetric metal insert with an explosive, which collapses in detonation the metal insert, which is usually in the form of a conical or hemispherical formed, thin-walled metal layer, along the charge axis corresponding to the axis of symmetry of the metal insert can.
  • the Metal insert is subsequently ejected in a jet-like manner along the charge axis from the shaped charge. The jet expands along the axis until eventually particleisation occurs.
  • shaped charges which are used for example in weapons for fighting armored vehicles, is therefore given at short distances of some charge diameters distance, so that a shaped charge is generally brought as a warhead on a missile to the target and triggered shortly before the target.
  • a shaped charge is for example in the DE 31 17 091 C2 .
  • DE 33 36 516 A1 or the DE 29 13 103 C2 explained.
  • the explosive amount at least partially enclosing encapsulations for example made of metal, known by the detonation in any or predefined fragments are broken up.
  • the energy released in the near field, ie in the immediate vicinity of the explosive is used in part to accelerate these fragments, for example in the form of splinters, which subsequently propagate over relatively large distances, limited by the delay due to aerodynamic forces and thus can cause a destructive effect at a greater distance.
  • the range of the splinters and the solid angle range covered thereby is greater than desired.
  • the propagation direction of the pressure effect in the near field is limited in an idealizing approximation to a two-dimensional disk.
  • the anisotropy of the pressure effect decreases rapidly with increasing distance from the charge, see for example: M. Held's "Impulse Method for the Blast Contour of Cylindrical High Explosive Charges", Propellants, Explosives, Pyrotechnics 24, 17-26 (1999 ).
  • the invention is based on the object, an explosive charge having a explosive material consisting of three-dimensional form and by means of the explosion, a spatial anisotropic pressure effect in at least one main direction of action, in which the pressure effect is greater than in other directions of action, as for example in the above Cylinder charge explained is the case in such a way that a significant improvement in the range of the pressure effect as well as the spatial focusability of the pressure effect in the detonation should be achieved. In particular, a controlled spread of the pressure effect in a sharply defined spatial direction should be possible. Expressly applies to avoid beam or projectile-like propagating body or splinters, especially since their range is not or very difficult to limit.
  • an explosive charge which has a three-dimensional form consisting of explosive material and unfolds by way of explosion a spatial anisotropic pressure effect in at least one main direction of action, is greater in the pressure effect than in other effective directions, formed by the explosive material existing spatial form one of Main effect direction facing, extending in the main direction of action surface area, are applied to the particles and / or on which a decomposing in the explosion of particles material layer is applied.
  • the particles are preferably made of non-metallic material and have a total mass that can be assigned to the particles, which is smaller than a mass that can be assigned to the explosive material.
  • a very marked increase in the pressure effect with simultaneously improved spatial focusing properties - i. a maximum pressure effect can be achieved in a very narrow spatial area - can be achieved by the spatial geometric design of the spatial shape of the explosive material, without using known per se, the pressure effect enhancing and the anisotropy of the pressure effect influencing, mostly consisting of solid materials Eindämmungen ,
  • the desired objectives can be achieved without any metal inserts, which unfold the effects known in this context in the hollow charges explained above.
  • the explosive material is suitable for the formation of a stable spatial form and has an intrinsically stable mechanical load-bearing capacity.
  • the spatial form of the explosive material predetermining envelopes or encapsulations are provided, which in turn are as detonation neutral, i. as far as possible have no effects negatively affecting the development of the pressure effect during the detonation of the explosive material.
  • the explosive material has a three-dimensional shape, which is plate-shaped or cup-shaped, wherein the hereinafter referred to as plate shape spatial form is rotationally symmetric and thin-walled and in particular provides a concave curved surface. It is further assumed that such an explosive charge in the region of the disk center point, which is to be regarded as the piercing point of the symmetry axis of the dish form, provides for initiating the detonation an ignition point.
  • the swath propagation and associated swath flow is primarily along the axis of rotation dictated by the dish shape, which extends virtually from the concave surface area of the plate shape to a spatial direction, referred to in further terminology as the main direction of action which results in a focusing of the associated with the formation of steam pressure effect.
  • the rate of vapor propagation along the main velocity of propagation in the atmosphere is related to the velocity of detonation in the explosive, ie the velocity at which the chemical vapor propagates Substance transformation within the explosive propagates to adapt.
  • the inclination or opening angle at which the concave surface area extends longitudinally to the main direction of action seems to be the inclination or opening angle at which the concave surface area extends longitudinally to the main direction of action. If the concave surface shape has a very large opening angle, ie the dish shape is very flat, the velocity component with which the chemical conversion propagates in the direction of the main action direction predetermined by the concave shape is smaller than in the case of a very strongly curved dish shape.
  • the steam propagation speed by suitable choice of the explosive material.
  • the opening angle of the concave surface form of a solution formed spatial form, which consists of explosive material, and the explosive material are chosen such that the initial Swath propagation velocity in the main direction of action and the rate at which the material transformation of the explosive spatially propagates in this direction are identical or substantially identical.
  • the above spatial forms are typically only provided with a single ignition point, at which the initial ignition triggering takes place, which is arranged in the symmetry point of the respective spatial form.
  • a made of explosive material spatial form which is not necessarily rotationally symmetrical about an axis of rotation, equipped with a plurality of spatially separated ignition points, which are arranged, for example, arrayed on a surface region of the spatial form and individually on a corresponding Ignition tripping unit can be triggered.
  • ignition points distributed around the axis of symmetry of the plate-shaped spatial form arranged ignition points can be ignited under specification of a specific time sequence and under specification of a certain Zündauslettesmusters, for example, does not necessarily provide the triggering of all existing ignition points, but rather only a selective selection of existing ignition points. In this way, it is possible, the main spatial direction along which a focusing of the detonation-related pressure waves takes place, predeterminable to pivot without changing the orientation of the spatial shape of the explosive charge.
  • the particles do not necessarily consist of metal, but preferably of vitreous or ceramic materials.
  • the particles should therefore as far as possible not be metallic, for example consist of ceramic materials. Due to this requirement, the explosive charge according to the invention differs in particular from those explosives to which heavy metal particles are added in order to increase the effect, the so-called dense inert metal explosive (DIME).
  • DIME dense inert metal explosive
  • the application of the particles or a material layer which disintegrates into particles by detonation onto the concave surface area of the spatial form is preferably carried out with adhesive substances for producing an intimate connection between particles and spatial form, which in turn are suitably selected and thus make a positive contribution to the overall effect can.
  • the explosive charge according to the solution enables a spatially extremely directed pressure effect whose range of action can be predefined.
  • the pressure effect at a great distance from the location of the explosive charge can be comparable to the effect of a ball charge, which is directly in contact with a target structure. It is essential that the extremely high pressure effect of the explosive charge formed in accordance with the solution unfolds at a large distance from the charge only in a defined solid angle range, the direction of which can be predetermined essentially by the geometric configuration of the spatial form and the method of ignition.
  • the range of the particle cloud can be influenced for a given total particle mass and quantity of explosive by selecting the size, mass and shape of the individual particles.
  • a rotationally symmetrical spatial form directed at a spatial point for example, the one in the Fig. 1 in perspective flat cone charge.
  • the trained as a flat cone explosive charge 1 has a concave surface area 2, which tapers in the figure representation in the plane of the cone in the region of the apex 3 converge.
  • the spatial form is thin-walled with a wall thickness of a few millimeters to a few centimeters, depending on the choice of the flat cone diameter formed. It is expressly noted that both at the in the FIG. 1 visible concave surface 2 as well as on the invisible back no Däfflemmungstechnik mandatory are provided, which affects the detonation effect of the explosive material of which the flachgegelige space shape of the explosive charge 1.
  • the flat cone shape provides an opening angle of about 130 °, wherein as explosive material Nitropenta (PETN) is selected and the ignition takes place in the center 3 of the flat cone charge, since in this case mitbestimmte by the spatial shape of the explosive material on the detonation speed of the explosive charge is tuned.
  • PETN explosive material Nitropenta
  • Focusing the pressure effect formed by the detonation of the explosive charge 1 can be observed along the cone symmetry axis A, along which the concave surface region 2 of the explosive charge extends in a conically widening manner.
  • the spatial shape of the explosive charge 1 carries a not shown occupancy of the concave surface 2 with non-metallic particles, for example in the form of glass beads or other non-metallic, preferably of ceramic materials particles, with a particle size down to micro or Nanometers to drastically increase the range of the near-field pressure effect due to a directed swath flow along the main direction of action A.
  • non-metallic particles for example in the form of glass beads or other non-metallic, preferably of ceramic materials particles, with a particle size down to micro or Nanometers to drastically increase the range of the near-field pressure effect due to a directed swath flow along the main direction of action A.
  • the concave surface portion 2 Particles P or a corresponding material layer which disintegrates by means of a detonation in a plurality of particles, a drastic increase in the range of the pressure effect can be achieved.
  • the particles contribute to a certain local penetration effect when hitting a target structure, the drastic increase in the range of the pressure effect is determined by the
  • Fig. 3 On the basis of in Fig. 3 shown image representations can be seen how large the pressure difference between a known cylinder charge, according to Fig. 3 (Above) and a solution formed flat cone charge with particle feed, acc. Fig. 3 (below), can be. So, suppose that in Fig. 3 (top), left view in the center, the cylinder charge is arranged with horizontally extending cylinder axis, which is ignited on the left side along the cylinder axis. To detect the pressure effect, a pressure sensor no. 1 along the cylinder axis and two pressure sensors no. 2 are arranged on both sides perpendicular to the cylinder axis.
  • FIGS. 4 a to e an alternative spatial form for the design of an explosive charge 1 is shown in perspective from different angles.
  • FIG. 4a has a spherically shaped surface area 2.
  • FIG. 4b which shows a side view of the explosive charge, it can be seen that neither the concave front nor the rear side is provided with denutment layers.
  • the drawn axis indicates the main direction of action A, in the case of ignition of the explosive charge at the ignition point Z1, which is interspersed by the axis of symmetry, equivalent to the main direction of action A.
  • FIGS. 4 c and d in each case the same dome-shaped explosive charge 1 is shown but now with two ignition points Z1 and Z2.
  • ignition of the explosive charge 1 at the ignition point Z1 would cause a pressure effecting the pressure to form along the axis A1.
  • the same explosive charge is ignited spatially at the point Z2, the result is a second main direction of action A2, which is pivoted about the main direction of action A1 and along which the pressure effect propagates focusing. It can thus be shown that by certain displacement of the ignition point to the spatial form of the explosive charge, the spatial direction along which the pressure effect propagates focusing, can be pivoted.
  • Fig. 4e shows an array-shaped arrangement of five ignition points Z1 to Z5, which are applied distributed on the back of the cup-shaped spatial shape of the explosive charge 1.
  • the individual ignition points Z1 to Z5 can be triggered individually, separately or in combination with a corresponding ignition trip unit.
  • the near-field-like pressure effect of the swath flow could be demonstrably transmitted over very large distances, compared with the dimensions of the near field of a conventional mass-like ball charge.
  • the measures required for this purpose take into account in particular the aspect of a technically simple and cost-effective implementation and can also be realized with a lower weight.
  • the increase in the pressure effect is not based on projectile-like properties or splinter effects, as in previous comparable known solutions, since projectiles or splinters fly along their trajectory over long distances, while the pressure effect of charges, which are designed according to the above principle, in the Range of pressure effect is effectively adjustable and thus limited. Threats caused by splinter flight can thus be effectively ruled out.
  • the explosive charge according to the invention can be used for a variety of scientific purposes, in technical processes and apparatus, for example by accelerating objects or for forming materials.
