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.
- HL threat shaped charges
- KE threat anti-aircraft missiles
- reactive protection with controlled ignition as active armor.
- reactive arrangements are a single-layer or multi-layer, one-sided or two-sided coating of the explosive with mostly metallic plates.
- Such arrangements are effective with appropriate dimensioning both against shaped charges and against KE projectiles and as protection modules worldwide in many armored vehicles in use.
- High-performance reactive protection systems known hitherto can not completely prevent the HL threat even through the use of considerable surface masses, since only a certain proportion of the shaped charge jet can be influenced by the disruptive measures. Therefore, usually about 20 to 30 percent of the power of the shaped charge ammunition must be compensated as a residual power from the base armor of the vehicle.
- the accelerated plates preferably consist of steel, as described for example in EP 0 379 080 A2.
- 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.
- US-A-5,824,951 a reactive armor is described in which the inert plates surrounding the explosive consist of different materials.
- the accelerated against the shaped charge jet plate is made of glass, which with the beam zufichten on the vehicle to be protected plate of steel. Behind the jet flying disk there is a cavity to not interfere with its movement for the period of interaction with the shaped charge jet.
- a reactive protection against shaped charges in which layers arranged obliquely to the direction of the bombardment explosive bombardment surface is occupied with interference layers made of fiber composite material to avoid hard splinters. 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.
- US-A-5,637,824 is a classical reactive composite armor having an explosive layer and a metallic plate accelerated in the direction of the threat. Due to the detonation, the HL beam is reduced in its performance in a layer of the explosive layer following, relatively thick, dynamically acting and dammed back by means of a metallic plate layer by jet disturbance. The dynamic effect of the intermediate layer can be enhanced by a layer introduced into the active zone and by a further explosive layer in front of the rear metallic plate.
- WO-A-94/2081 1 is a conventional reactive arrangement with two mutually inclined, bilaterally occupied explosive layers in a solid metallic housing.
- the subject matter of the invention was not the classical reactive sandwich arrangement with metallically accelerated plates, which was assumed to be known, but the nature of its arrangement in a solid housing. This setup has provided protection against both HL and KE threats. Such structures are used in a number of armored vehicles of Soviet origin.
- the arrangement described in DE 33 13 208 C therefore has the aim of effecting 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 1 32 A relates to 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.
- the problem underlying the invention is to protect medium-weight and even only slightly armored vehicles with correspondingly low basic protection against shaped charges, in particular against medium-sized shaped charge projectiles such as PG-7 without causing additional ballistic effective
- Such HL protection for light armored vehicles requires: a very high effectiveness of the protection arrangement, a low basis weight while minimizing residual power; the vehicle wall must not be subjected to undue force or penetration by the threat or parts of the protection system; there must be no fragmentation of the vehicle environment due to the protection system; the mobility of the vehicle must not be restricted; parts of the protection system may need to be installed or removed during the mission; the respective road traffic licensing regulations (for example in Germany: StVZO) must be met; there must be no danger beyond the protection system due to the explosive on the vehicle, i. in Germany e.g. Classification 1 .4 according to the Dangerous Goods Ordinance (GGVS); with mounted protection, fast access to flaps and storage spaces must be possible.
- GGVS Dangerous Goods Ordinance
- 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 ,
- a 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.
- the pyrotechnic structure is at least approximately in a dynamic equilibrium over the entire time of action and exerts no end ballistisch relevant or destructive influences on its environment, ie 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 °.
- M / C ratio of the mass of wall and explosive
- Index 1 front surface
- index 2 back surface
- V2 A V1.
- Fig. 4A Symmetrical assignment by means of pure explosive films. Of course, this also includes films with surface treatment or surface protection. This results in a first approximation simultaneous detonation.
- the "dynamic dam" by the detonation gases increases the effective damming mass and results in a maximum surface velocity of the order of the swath velocity
- the wall itself does not experience acceleration
- the velocity of the reaction gases can be significantly affected by the film design and the selected explosive In the case of an occupancy of the explosive layer with a massive layer, as is predominantly the case with classic sandwich structures, this possibility of influence is severely restricted.
- FIGS. 5B and 5C The explosive films in the structure corresponding to FIG. 5A are coated with a very thin layer either on the wall side (support side) or on the outside (threat side and object side).
- a very thin layer either on the wall side (support side) or on the outside (threat side and object side).
- 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 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.
- these are relatively difficult not least because of the required thicknesses in the mass balance of an armor.
- reactive armor the influence of element size on the dam, and thus on the speeds achievable by the accelerated components, is of great importance. It is easy to see that small element sizes and larger explosive thicknesses as well as higher element masses reduce the speed. The speed of a small-area element is reduced all the more, the thicker (more massive) the coverage and the thicker the explosive layer is.
- this can also serve as a control element for the energy and signal transfer between the explosive films.
- a design criterion for this is the acoustic impedance of the 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 metallic foams.
- air as ambient 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. 9 example of a pyrotechnic arrangement with container / housing.
- FIG. 10 shows another example of a pyrotechnic arrangement with container /
- FIG. 1 1 further example of a pyrotechnic arrangement with container /
- Fig. 1 shows the basic structure of a pyrotechnic protective surface according to the invention with the incident shaped charge jet or the impending threat 1, the pyrotechnic assignments 2 and 3 and the carrier therebetween. 4
- FIG. 2 shows the state or mode of operation of the pyrotechnic protective surface according to FIG. 1 at a relatively early point in time of the penetration 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).
- 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 (for example as KE protection or protection against flat-cone charges) or extremely light in design. 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.
- FIG. 5 shows some examples of pyrotechnic protective surfaces (here symmetrically arranged) with extended carriers or inner surfaces (FIGS. 4A, 4B, 4C). As described, these may consist of extremely lightweight materials or, at the same time, serve as internal volumes (e.g., containers) for other purposes. Of course, the design of these inner regions have no limits, as far as the mode of action of the reactive components is not unduly limited.
- one and / or two-sided assignments of the explosive surfaces in the inner and / or outer region are in particular for the overall efficiency An armor of great importance and also for the distribution of the still necessary protection against the remnant penetration depth of the threat.
- the one- or two-sided dam 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 dam of the explosive to increase the overall protective effect is advantageously carried out with disintegrating materials such as surfaces of metallic or non-metallic films, GRP, ceramic or glass or liquids and gels.
- the materials of the dams in quantity and density are advantageously to be selected such that in combination with the pyrotechnical layers one or more of the Däfflemmungs slaughteren are set in motion as early as possible in order to disturb the front fast parts of the shaped charge jet and one or more damming materials are set in motion more slowly so that they can interfere with the slower central and rear portions of the shaped charge jet.
- the explosive layers may be embedded in one or more low density metallic or non-metallic materials (1- 5-30 kg / m 3 ) and high compressibility as a matrix (see Figure 6).
- the design of the carrier 4 is completely free. It is therefore shown in Fig. 1 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, the minimum angle is 10 ° to 1 5 ° lower in the arrangement proposed here 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 performance of a protection arrangement is generally judged as the ratio of the reference mass (performance of the ammunition in armor steel equivalent) to the mass of the protection arrangement itself by two factors:
- the Em-factor serves as a criterion for assessing the quality of a total protection.
- a partial protection measure i. in the case of residual power still remaining, the assessment 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 according to Fig. 5A.
- the hollow charge is positioned at a distance of 1 5 before the reactive protection arrangement. This consists in the simplest form of the inclined to the beam axis 1 explosive layers 1 6 and
- the protection arrangement according to FIG. 6 was tested experimentally at 45 ° with a PG 7 type experimental charge 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 1 5 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 weight per unit area (-100 kg / m 2 compared to 300 kg / m 2 ).
- both the front explosive layer 16 and the rear explosive layer 1 7 on the side of the carrier were dammed with a medium density brittle material (20, 20A) (Figure 7). Because of the relatively thin inner layer of foam 19, this is a particularly flat protective structure according to 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 up to 1, 5, the special performance of this protection arrangement according to the invention is particularly evident in terms of 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.
- the interconnection of two relatively thin pyro-technical protective surfaces creates a new, highly effective protective surface whose total explosive thickness is still lower than that of the known reactive armor.
- 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 possibilities relating to the ignition of the pyro-technical surface. This includes the triggering by a direct admission or over Zünd Anlagenn up to a controlled spark ignition. Likewise, all options concerning the cladding or sheathing 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).
- any layers or structures may be occupied on one or both sides with a pyrotechnic protective 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.
- the pyrotechnic protection device or protective surface has a minimum basis weight.
- the pyrotechnic protection device or protective surface requires a minimum depth.
- the pyrotechnic protective surface is basically a free element and therefore not bound to any other technical equipment.
- the pyrotechnic protection device has an optimal overall efficiency in terms of mass and depth of protection.

- the pyrotechnic protective surface may be rigid or deformable / movable.
- the pyrotechnic protective surface can be attached to existing surfaces in any manner fixed or detachable.

- Pyrotechnic protective surfaces can occupy any layers or structures on one or both sides.
- pyrotechnic surface can be used as a standalone device or combined with other armor (for example, against KE and FK threats).
- the pyrotechnic protection device can be effectively combined with bellows arrangements because it can withstand the high jet speeds degrades and thus increases the effectiveness of Beulblechanodnitch (Beulsandwichs).
- Pyrotechnic surfaces can be used as the most efficient multi-layered sheet modulus, e.g. be used against threats relatively large caliber mono-shaped charges or HL-tandem threats.
- the pyrotechnic protective surface does not require any sophisticated technical requirements (for example with regard to manufacturing processes, manufacturing tolerances and homogeneity of the explosive).
- Pyrotechnic protective surfaces can be adapted to the state of the art without much effort.
- the carrier of a pyrotechnic protection device may consist of an inert material or of a hollow or filled structure.
- the support of the pyrotechnic protective surface can be minimized as a mere mounting or mounting surface or, depending on the design (for example multi-layered or as a technical structure), meet ballistic or technical additional requirements within wide limits. And this without reduction or disturbance of the basic performance of the arrangement.
- pyrotechnic protection surfaces can be covered with pyrotechnic protection surfaces.
- pyrotechnic protective surfaces By means of pyrotechnic protective surfaces according to the invention, a highly effective protection against HL threats in light vehicles or unarmored facilities is also possible for the first time.
- Pyrotechnic protective surfaces can be used as a supplement and / or as an active component in active armor. Pyrotechnic protective surfaces can be used for active armor both signal transmission (detonation transmission) and as active surfaces.
- the respective explosive layers may optionally be enclosed by one or more chambers provided with fillers or air. Further embodiments of the invention, in particular with regard to their use and operational capability in light vehicles or means of transport will be briefly listed below.
- the housing (see Fig. 9 to 1 1) may consist of an elastic, metal-free, no splinter-forming material such as elastomers, thermoplastics or thermosets. Furthermore, from resilient materials such as foams or sintered materials, fiber composite materials, a material of renewable resources, wood or synthetic wood, an organic material (paper, leather), a textile material or a combination of these materials.
