Definitions

  • the present invention relates to a pyrotechnic protection, and more particularly to a shatterproof reactive protection device against shaped charge threats.
  • the protection of light and medium armored vehicles against such antitank handguns is only very limited or no longer possible with conventional reactive and especially passive protection systems, because the payload of the vehicles is limited and necessary for the protection of the surface weight of the armor is too high.
  • the lighter vehicles have only thin wall thicknesses, as the basic vehicle protection is usually designed only for small-caliber armor-piercing ammunition in caliber to 14.5 mm. Therefore, various reactive, i. explosive protection systems have been developed to reduce the basis weight required for protection.
  • the HL-protection of medium armored vehicles with a basic protection of about 30-50 mm armor steel equivalent with passive protection systems requires an additional basis weight of the order of 500 kg / m 2 and with previously known, already powerful reactive protection systems still an additional basis weight in of the order of magnitude of 300 kg / m 2 against the threats of PzAbwHWa.
  • the accelerated plates are preferably made of steel, such as in the EP 0 379 080 A2 described. According to this disclosure, the reactive protection is combined with additional passive protection to compensate for the portion of the shaped charge jet which is not sufficiently dissipated by the reactive protection.
  • At least one interference layer is formed from a high-strength fiber composite material in the form of a textile fabric of artificial or renewable raw materials or their combination.
  • the DE 199 56 197 A describes a classic reactive armor, in which only the usual metallic component to avoid structural and environmental damage by a non-metallic plate (preferably made of fiber composite material) is replaced.
  • the protective effect against HL and KE threats is protected by the Achieving acceleration of one or more such plates, wherein the reactive assembly is disposed in a non-metallic housing.
  • the described function of an additional, called Beulblech plate is incomprehensible.
  • the front damming is formed only by a non-metallic protective layer, which then requires an increased explosive thickness to produce the internal pressure required for a dynamic effect.
  • the structure again represents a conventional reactive armor with an occupied on both sides explosive layer.
  • both the environment and in particular the structure are charged.
  • the in the DE 33 13 208 C The aim of the described arrangement is therefore to effect a jet disturbance comparable to that of the so-called crater breakdown by means of a porous or foamed layer with incorporated explosive component used in a conventional reactive armor. This layer is covered in particular on both sides with metal plates for protection against KE threats and thus represents again a reactive sandwich of conventional design.
  • DE 102 50 132 A concerns protective arrangements against blast-producing and projectile-forming mines, but not against shaped charges.
  • the protective effect is carried out via containers with a filler of a liquid or a flowable medium. Basically, this is a dynamic protective structure, but not a reactive device to ward off HL threats.
  • EP 0 689 028 A1 a protection device on which the preamble of claim 1 is based.
  • this object is achieved in that at least two layers of a pyrotechnic material of the same or different proportions and / or thicknesses are arranged at a distance from each other freely or in a housing made of a non-metallic material such as rubber at an angle to the direction of bombardment ,
  • Advantageous embodiments and modifications of the invention are the subject of the dependent claims.
  • this pyrotechnic protective structure consists of a carrier of any shape inclined in the area of impact or impact of the threat onto which pyrotechnic layers are applied on both sides.
  • shock waves and reaction gases are formed and accelerated both against and in the direction of the penetrating threat.
  • both the front, high-performance radiation elements and a crucial part of the total beam length are disturbed in shaped charges and thus lose their breakdown power.
  • the pyrotechnic structure is at least approximately in a dynamic equilibrium over the entire action time and exercises no end ballistisch relevant or destructive influences on its environment, i. neither on the outside nor on the structure to be protected itself.
  • the size of the required salaried area results from simple kinematic considerations of the penetration process.
  • the proposed pyrotechnic protection surface is suitable for effecting a large increase in the level of protection in a number of known armor both by an upstream circuit as well as by integration.
  • pyrotechnic protective surfaces can be easily combined with arrangements against KE threats. In any case, protective optimizations against several types of threats require little or no dead mass.
  • the amount of explosive per unit area to be used compared to previously known reactive armor be significantly lower, taking into account the above limitations up to 50%.
  • the thickness of the explosive coverings can be about 50% of the mean beam diameter at an angle between the defense area and the threat above 30 °.
  • the explosive films or the assignments may have varying thicknesses.
  • the effectiveness of a sub-area such as to compensate for different depths of protection or employment, are influenced.
  • a thicker supporting layer or a separating layer between the explosive films with additional physical properties, for example with respect to the dynamic behavior or specific properties with respect to shock waves, may be advantageous because the engagement depth is increased, ie several jet particles or a larger beam length remains engaged there .
  • Known explosive dynamically compacted glass body work on this basis. However, these are relatively difficult not least because of the required thicknesses in the mass balance of an armor.
  • this can also serve as a control element for the energy and signal transfer between the explosive films.
  • One design criterion for this is the acoustic impedance of the materials used.
  • a further improvement results from the basically known method of coating the surfaces of the pyrotechnic layers with materials of different densities.
  • brittle, decomposing or delaminating materials such as glass, composites, ceramics or shock-resistant, but at relatively low deformation velocities soft materials such as rubber is used, which with its high inertia after a relatively long response over a longer period of time dissipate or erode the middle and back portions of the shaped charge jet.
  • Suitable materials of low density are, for example, metallic or non-metallic Foams.
  • air as a surrounding medium achieves a short response time and very high acceleration for dispersing the fast parts from the front region of the shaped charge jet because of its low inertia.
  • Containers, housings or covers are used primarily for fixing or protecting the active layers, also in conjunction with protective components to be combined and against external influences.
  • the layers of explosive and inert materials are placed in prefabricated pockets of the protection module, whereby a simple and production-appropriate adaptation of the reactive protection to the vehicle to be protected can be made.
  • FIG. 1 the basic structure of a pyrotechnic protective surface according to the invention with the impinging shaped charge jet or the impending threat 1, the pyrotechnic assignments 2 and 3 and the carrier 4 therebetween.
  • Fig. 2 shows the condition of the pyrotechnic protective surface Fig. 1 at a relatively early stage of the intrusion and penetration process.
  • the initiation of the front (threat facing) pyrotechnic occupancy 2 takes place at the point of impact from 1 to 2 (small circle 5).
  • the detonation front propagates in FIG. 2 at a speed which is on the order of magnitude of the average beam penetration speed in the part of the shaped charge jet to be defended (symbolized by the arrows 6).
  • initiation takes place in the rear pyrotechnic coating 3, both by the shock waves propagating from 5 in a hemispherical manner and by the penetrating beam tip at the impingement point of 1 to 3 (small circle 5A).
  • the foremost beam parts still pass through the front pyrotechnic layer 2. They are intercepted in the rear pyrotechnic covering 3. Because of the prevailing physical conditions, the geometric conditions and the occurring velocities in connection with the short response times, the foremost beam peak is reached in the rear zone, so that a total of full load, deflection and thus destruction of a large part of the shaped charge jet including the foremost particles takes place.
  • Fig. 4 shows examples of symmetrical or asymmetric pyrotechnic protective surfaces with carriers positioned therebetween. These can be both protection-relevant (eg as KE protection or protection against flat cone charges) or extremely lightweight. Corresponding reactive arrangements may be formed from a single (planar or curved or arbitrarily shaped) element or may be combined to form a surface by the combination of two or more elements. This makes it possible to adapt the reactive protection according to the invention to the threat.

  • 4A, 4B, 4C extended carriers
  • one and / or two-sided occupancies of the explosive surfaces in the interior and / or exterior in particular for the overall efficiency of armor of great importance and also for the distribution of the still required Protection against the remnant penetration depth of the threat.
  • the one- or two-sided entrainment of one of the explosive layers can be advantageous for the overall balance of the protective effect or in conjunction with design specifications.
  • Such a containment of the explosive to increase the overall protective effect advantageously takes place with disintegrating masses such as e.g. Surfaces of metallic or non-metallic foils, GRP, ceramic or glass or liquids and gels.
  • the materials of the densities in density and density are advantageously to be chosen so that in combination with the pyrotechnic layers, one or more of the Däfflemmungs slaughteren are set in motion as early as possible to disturb the front fast parts of the shaped charge jet and that one or several damming materials are set in motion more slowly so that they can interfere with the slower middle and rear regions of the shaped charge jet.
  • the explosive layers may be embedded in one or more metallic or non-metallic low density materials (15-30 kg / m 3 ) and high compressibility as matrix (cf. Fig. 6 ).
  • the design of the carrier 4 is completely free. He is therefore in Fig. 1 shown as a curved surface. What is needed is a sufficient bias towards the threat in the area of impact. Due to the high efficiency of the pyrotechnic coating, in the arrangement proposed here, the minimum angles are lower by 10 ° to 15 ° compared to known reactive structures. Since a minimum inclination angle of 45 ° is assumed for sandwiches of conventional construction, with the present arrangement a mean angle between threat and defense of 30 ° to 40 ° is sufficient. The angle between the defense surface and the threat can be formed by the employment of the entire surface or by geometric modifications by technical or constructive measures.
  • the required inclination can be achieved for example by corrugation, bending or lamination.
  • the different embodiments of the pyrotechnic protective surface can be a form a continuous surface or consist of individual modules with gaps or other separations (eg area segments, blinds, separate or interlocking modules).
  • the technical design of the carrier is in principle not subject to any restrictions (for example metallic, non-metallic, structured, single-layer or multi-layered).
  • the carrier may be rigid or deformable / movable and its thickness may range from film thickness to a solid plate or thicker structure. Furthermore, it may consist of an inert material or of a chemically / pyrotechnically reactive substance. This can be built in this carrier by the detonation of the pyrotechnic assignments and an inner high-pressure field.
  • the Em-factor serves as a criterion for assessing the quality of a total protection.
  • the evaluation of the individual protection arrangements is usefully carried out via the Fm factor, in order to be able to evaluate their quality comparatively.
  • the achievable Fm values in the current state of the art are in the range of 5 for passive protection arrangements and in the range of 8 to 10 for reactive arrangements.
  • An arrangement according to the invention fundamentally requires the use of pyrotechnic substances with a dynamic corresponding to the application, ie, reactivity.
  • the handling of the pyrotechnic required here Elements and the associated safety precautions and other operational requirements are significantly improved by the fact that the necessary technical requirements for the support structure or the vehicle due to the described advantages can be conceived very low.
  • the duration of use of an effective pyrotechnic coating can be minimized by appropriate precautions.
  • Fig. 6 shows a basic structure accordingly Fig. 5A ,
  • the shaped charge is positioned at a distance 15 in front of the reactive protection arrangement.
  • this consists of the explosive layers 16 and 17 inclined to the beam axis 1.
  • the layers 18, 19 and 20 are used to fix the explosive layers 16 and 17 in a pure state.
  • These layers 18, 19 and 20 can also serve as very lightweight insulation.
  • the required propagation speed of the surface must not be significantly restricted.
  • Fig. 6 was tested experimentally at 45 ° with an experimental charge of type PG 7 at a distance (15) of about 2.5 calibers.
  • the protective structure consisted of foam / explosive / foam / explosive / foam, the basis weight was at a density of the foam of about 15 kg / m 3 less than 30 kg / m 2 in LoS (Line of Sight).
  • the experimentally determined residual power was about 30% of the power of the shaped charge in armored steel. This results in an extraordinarily high Fm value of over 70.
  • end-ballistic relevant parts are not generated either in the direction of the threat or in the direction of the object to be protected.
  • the front explosive layer 16 was dammed with a relatively thin layer of medium density material.
  • the residual power was only about 10%. This gives an Fm value of over 25.
  • the difference with the protective arrangement according to the invention becomes clear both with respect to residual power (10% compared to about 30%) and basis weight ( ⁇ 100 kg / m 2 compared to 300 kg / m 2 ).
  • both the front explosive layer 16 and the rear explosive layer 17 on the side of the carrier with a medium density brittle material (20, 20A) was dammed ( Fig. 7 ). Due to the relatively thin inner layer of foam 19, this is a particularly flat protective structure after FIG. 5B , At a basis weight of the reactive protection arrangement of less than 90 kg / m 2 , the residual power was less than 10%. This gives an Fm value of over 30.
  • the residual power of the shaped charge must be compensated by ballistically effective materials. Since even materials such as armored steel, high-strength duralumin or titanium only achieve efficiencies of up to 1.5, the special performance of this protection arrangement according to the invention becomes clear, in particular with regard to its use in light systems. The extremely low residual power achieved confirms that the use of such a reactive protection arrangement according to the invention for medium and even light armored vehicles is made possible.
  • the area of an object to be protected is, for example, 6 m 2 (eg side protection)
  • a total protective weight of 4680 kg is required.
  • the residual power of the reactive protection arrangement according to the invention is only at a maximum of 10 mm armor steel equivalent, corresponding to a basis weight of 80 kg / m 2 .
  • a reactive protection arrangement according to the invention only about 32% of the protective mass of conventional reactive protection arrangements is needed.
  • the pyrotechnic coating of the protective surface may consist of a coating, a fixed or applied explosive film, an applied reactive mixture (for example metallic admixtures to increase the efficiency of interference) or else a rigid or deformable container (bag) containing a pyrotechnic active agent.
  • a rigid or deformable container bag
  • its walls must be designed in such a way that the described mode of action of the pyrotechnic protective surface is not impaired. However, this is ensured with thicknesses of the components in the order of tenths of a millimeter.
  • the metallic or non-metallic shell of such a container or the surface of the explosive film may also result from the manufacturing process.
  • casings or surfaces may also be required for protection against handling and application stresses as well as environmental influences.
  • Pyrotechnic protective surfaces can be easily combined to achieve the necessary deflection effect, for example, against relatively severe threats. For example, formed by the interconnection of two relatively thin pyrotechnic protection surfaces a new, highly effective protective surface whose total explosive thickness is still lower than that of the known reactive armor. Thus, even with the use of two pyrotechnic protective surfaces due to the further reduced residual power nor these high efficiency values are achieved or even larger shaped charges are very effectively intercepted. This is especially true for tandem arrangements.
  • Known reactive protective devices must be used to derive or transmit all the possibilities relating to the ignition of the pyrotechnic surface. This includes the triggering by a direct admission or over Zünd Anlagenn up to a controlled spark ignition. Likewise, all the possibilities of covering or cladding of the pyrotechnic surface shall be deduced or transferred. This includes the incorporation (or packaging) in a pure protective film (for example, against weathering, for shock or Abriebêt during transport or to color the surface).
  • the highly efficient reactive protection devices or protective surfaces according to the invention also largely eliminate the use of highly complex and highly failure-prone active protection techniques. Such systems should provide a further increase in protection against classic reactive protection systems, especially where the threat of the object itself with powerful known reactive devices is no longer fending off or the object to be protected itself would be too much burdened or even destroyed by the reactive armor ,
  • the reactive surfaces according to the invention can provide a decisive advantage in that such modules with the lowest surface masses and even with arbitrarily shaped or very small element size provide high protection performances. This is particularly useful in actively accelerated protective elements to bear, since they require only relatively low energies according to the very low masses for their acceleration.
