Definitions
- the present invention relates to a process for the production of a protective layer with matrix-like rods protruding from a surface, anti-unguided and / or flying in the lower scarf medium caliber projectiles with electric impact detonators.
- a process for the particularly economical production of a protective layer is to be created.
- This method is inventively achieved in that are cut out of a metal strip at equal intervals surfaces with a U-shaped contour, so that rods remain with a web.
- punching tools can be used.
- the rod-shaped metal strips are protective; the webs are only the support and take over the task of a plate.
- the cut sheet metal strips are placed with their web on support and connected to these non-positively.
- FIG. 1 1 is a protective layer.
- rods 3 are used in a matrix-like manner and are fixed on the back side with flanges 4 on the base plate 2.
- the rods 3 project beyond an inner surface 2 'by a length l 1 .
- a bullet 100 in the direction of flight F impinging on an object O to be protected penetrates with its impact fuze 102 between the bars 3 a.
- a thin-walled double hood 101 of the projectile 100 is thereby perforated and electrically short-circuited by the end portions 3b of the rods 3, so that the front-side impact fuse 102 with its piezo sensor can no longer be effective.
- the double hood 101 is, physically considered, a two-wire planar line for the ignition energy.
- the diagonal distance a between the bars 3, 3a, 3b of a matrix of a plurality of bars 3 is at a maximum smaller than the caliber K of the active projectile.
- the double hood 101 is thereby "impaled” and short-circuited, but at least compressed; see partial section illustration in Fig. 1 ,
- the entire length l 0 of the hood 101, measured from the tip of the Auftschzünders 102 to the largest diameter of a lining 104 of a shaped charge 103 is shorter than the free length l 1 of the rods 3.
- the tips 3 'of the rods 3 are sharp-edged and made of hardened steel and / or have a galvanically conductive coating.
- Fig. 2 shows the unfavorable case of an obliquely striking the bars 3 projectile, with only the hood 101 and the impact fuze 102 are drawn.
- the piezo-generator can be activated before the hood 101 is pierced, so that further protective measures in the protective layer 1 are imposed.
- Fig. 3 shows a similar situation, but here the probability of ignition of the shaped charge is already much smaller, since a rod 3 has already pierced the hood 101 before touching the Auftschzünders 102 with another rod and shorted.
- Fig. 4a and 4b show measures to improve the protective effect. It has been shown that piezoelectric impact detonators directly striking the tips 3 'of the bars 3 directly on the front are often completely destroyed before they generate a sufficiently high ignition voltage. The prerequisite for such a destruction are extremely high surface pressures, ie pulses such as those caused by a blunt cone 5 with a sharp-edged tip 6 (FIG. Fig. 4a ) or by a sharp-edged pin 7 of 1 to 2 mm in diameter ( Fig. 4b ) be achieved.
- ie pulses such as those caused by a blunt cone 5 with a sharp-edged tip 6 (FIG. Fig. 4a ) or by a sharp-edged pin 7 of 1 to 2 mm in diameter ( Fig. 4b ) be achieved.
- Fig. 5 Based on the knowledge from the FIGS. 2 and 3 are according to Fig. 5 the rods 3 at an inclination angle ⁇ inserted into the base plate 2, in which case a fictitious flight direction F f was assumed, which corresponds to the threat situation.
- the inner surface of the base plate 2 is in turn denoted by 2 '. This allows, like Fig. 5 shows, also optimally protect inclined surfaces.
- Fig. 6 shows a protective layer 1 with an inner crush layer 8 made of a corrugated perforated steel sheet, which can absorb kinetic energy if the projectile obliquely penetrates and / or its charge is ignited.
- the effect of a shaped charge jet is reduced even then, because the optimal distance to the target, ie the object to be protected O, is exceeded by 2 to 3 times the caliber (stand off). So that the effective length l 1 (see. Fig. 1 ) of the bars 3 is not exceeded, the highest position of the surface 2 ', ie the "wave peaks" of the layer 8 is selected as a measurement basis.
- the bars 3 are covered by a lightweight foam 9 (commercially available polymer). Covers 10 are made of thin-walled aluminum plates on the side.
- the object is after Fig. 7 constructed, here the crush layer 8 consists of a composite plate of metal and plastics.
- the measuring base, the surface 2 ', for the length l 1 of the rods 3 is marked here.
- Fig. 6 is an all-round coverage of the modular protective layer 1 with UV-resistant plastic plates.
- Fig. 8 are on an armored vehicle 110, the windscreens with a protective layer 1, which is transparent and adjustable.
- the in rows R1 to Rn, in side bearings 13 'tiltably arranged rods 3 leave be adjusted by a drive 13 with articulated joints 12 to the current threat situation.
- the drive 13 is installed in a known roof protection 16 and therefore shown in dashed lines.
- FIG. 1 is a particularly, weight-saving development drawn.
- a rod 3a is made of a rigid composite with carbon fibers. To improve the conductivity of this is metallized at its threat facing surface 3a to one third of the total l 1 length and wear metallic tips 3 '.
- the most hardcoat possible is a galvanically conductive layer m, which optionally consists of titanium carbonitride (TiCN) or titanium nitride (TiN) in the present case.
- TiCN titanium carbonitride
- TiN titanium nitride
- the color of the coating is chosen according to the camouflage color of the object.
- Another advantage of this embodiment is the small “Radarquerexcellent", ie it contributes little to the radar detection and does not affect the other means for "camouflage".
- Rods in this embodiment are mainly for movable protective layers, analog Fig. 8 intended.
- An armed tracked vehicle Fig. 9
- an armored infantry fighting vehicle 111 for a protected troop transport is provided with modular protective layers 1 according to FIG Fig. 7 equipped.
- the two movable optical sensors 112 are protected against direct bombardment by adapted side covers 10 (protective layers), with integrated rods 3.
- Out of drawing Reasons here is the also existing lightweight foam layer, cf. Fig. 6 and 7 not shown.
- Such protective layers 10 are recommended for all inputs and outputs, such as for air inlets and exhaust openings on vehicles or stationary systems.
- side air intakes 17 are provided with rods 3 and thus protected.
- a variant of a protective layer 1 ' which does not form part of the invention consists of a steel net known per se Fig. 10 , in whose node 14 rods 3 are used.
- the rods 3 are protected by means of a respective gusset plate 15 from twisting. Again, here is the measurement base for the length of the bars 3, the surface 2 ', which corresponds to the maximum height of the gusset plates 15. Welding points are not shown on the gusset plates 15, which give the rods 3 the necessary stability.
- the node lobes 15 take over together with the mesh of the network 2a, the function of a plate 2, 2 '; see. Fig. 1 to Fig. 7 , In contrast to a plate, however, a net 2a can easily be adapted to the spatial forms of an object to be protected.
- the bars 3 are made of a protective layer of individual sheet-metal strips 50 which have been cut out by means of blasting (laser) the length l 1 plus a design adapted web width 51, which is determined depending on the base plate or support R1-Rn. To reduce weight recesses A were cut out.
- the matingly fitted parts are - in FIG. 11 not shown - non-positively welded together.
- the sheet metal used for the rods 3 " is steel sheet of a few millimeters in thickness, also high-strength aluminum sheets can be used.For this purpose, a well-known beam processing by means of high-pressure water jet application.
- the webs take over the function of the plate ( Fig. 1 to Fig. 7 ).
- This variant allows you to equip a property protection at very short notice.
- With appropriate dimensioning of the webs (bendable Quetene) and curved surfaces can be occupied by a protective layer without gaps.
- the after Fig. 11 realized protective coatings are characterized - compared to conventional protective measures - by a relatively low basis weight of 40 kg / m 2 (average).
- the subject invention can be adapted within wide limits to the threat situation.
- the materials and technologies used are conventional and can be substituted by new and better materials, including composites.
- the article can be adapted in an analogous manner to the object to be protected already existing means against the detection by means of electromagnetic radiation or it can be integrated.
- rods and metal parts 3,3b, 3 ", R1-Rn to ground (ground) to connect, so that all in the activation of the ignition device existing potentials are safely dissipated before they can reach the ignition chain.
- the subject invention is not limited to projectiles with shaped charges. It can be used against all Geschose whose ignition process is disturbed by an electrically short-circuited or connected to ground, flat connection line. It can be assumed that the nominal ignition energy of an impact fuze is necessary for the initiation of an active charge and that any still present partial flows are not sufficient for this purpose.

Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Schutzschicht mit matrixförmig angeordneten, aus einer Fläche herausragenden Stäben, gegen ungelenkte und/oder im Unterschalbereich fliegende Mittelkalibergeschosse mit elektrischen Aufschlagzündern.The present invention relates to a process for the production of a protective layer with matrix-like rods protruding from a surface, anti-unguided and / or flying in the lower scarf medium caliber projectiles with electric impact detonators.
Im zweiten Welkrieg wurden erstmals gegen gepanzerte Ziele Geschosse mit Hohlladungen abgefeuert. Dies einerseits von den US-Streitkräften (Bazooka genannte Waffe) und anderseits von Deutschland (Panzerfaust und Panzerschreck genannt). Zur Beschleunigung der Geschosse dienten Treibmittel wie Ladungen und Treibpatronen. Danach entwickelte Russland eine weitverbreitete Waffe, die als RPG (Rocket-Propelled Granade) bezeichnet wird. Diese wird in einer seit 1961 hergestellten Version noch heute, vor allem im Bereich der asymmetrischen Kriegsführung als Typ RPG-7, mit verschiedensten Hohlladungen, eingesetzt. Während die frühen Systeme mechanische Aufschlagzünder besassen, sind die neueren mit frontseitigen piezoelektrischen Zündvorrichtungen ausgerüstet und weisen zwischen dem Zündgenerator und der Zündkette flächige, galvanisch leitende Verbindungsleitungen auf. Diese relativ einfachen, meist raketengetriebenen Mittelkalibergeschosse sind weltweit verbreitet und stellen ein gewaltiges Gefahrenpotential dar; sie sind billig zu erstehen, leicht handhabbar und werden in verschiedensten Ausführungsarten gegen stationäre und mobile Objekte, insbesondere gegen leicht gepanzerte Fahrzeuge eingesetzt.In the second world war, projectiles with shaped charges were fired for the first time against armored targets. This on the one hand by the US armed forces (Bazooka called weapon) and on the other hand of Germany (Panzerfaust and Panzerschreck called). Propellants such as cargoes and propellant cartridges were used to accelerate the projectiles. After that, Russia developed a widespread weapon called the RPG (Rocket-Propelled Granade). This is used in a version produced since 1961 still today, especially in the field of asymmetric warfare as a type RPG-7, with a variety of shaped charges. While the early systems had mechanical impact igniters, the newer ones are equipped with front piezoelectric igniters and have planar, electrically conductive interconnections between the igniter and the igniter. These relatively simple, mostly rocket-propelled medium caliber projectiles are distributed worldwide and represent a huge potential for danger; They are cheap to buy, easy to handle and are used in various embodiments against stationary and mobile objects, especially against lightly armored vehicles.

Erfindungsgemäss soll ein Verfahren zur besonders wirtschaftlichen Herstellung einer Schutzschicht geschaffen werden.According to the invention, a process for the particularly economical production of a protective layer is to be created.
Dieses Verfahren wird erfindungsgemäss dadurch gelöst, dass aus einem Blechstreifen in gleichen Abständen Flächen mit U-förmiger Kontur herausgeschnitten werden, derart dass Stäbe mit einem Steg verbleiben. Hierzu lassen sich auch Stanzwerkzeuge verwenden. Dabei sind die stabförmigen Blechstreifen schutzwirksam; die Stege dienen lediglich der Halterung und übernehmen die Aufgabe einer Platte.This method is inventively achieved in that are cut out of a metal strip at equal intervals surfaces with a U-shaped contour, so that rods remain with a web. For this purpose, punching tools can be used. The rod-shaped metal strips are protective; the webs are only the support and take over the task of a plate.
Mittels Strahlbearbeitung (Laser, Wasserstrahl etc.) lassen sich sehr leichte und kostengünstige Schutzschichten aus Flachmaterial (Blech) herstellen, die auch integrierbar in verschiedenste System sind.By means of jet processing (laser, water jet, etc.), very light and cost-effective protective layers can be left out Produce flat material (sheet), which can also be integrated into a variety of systems.
In einer weiteren bevorzugten Ausführung werden die ausgeschnittenen Blechstreifen mit ihrem Steg auf Träger aufgesetzt und mit diesen kraftschlüssig verbunden.In a further preferred embodiment, the cut sheet metal strips are placed with their web on support and connected to these non-positively.
Zur Gewichtsreduktion in mechanisch schwach belasteten Stegen und Trägern werden zudem in gleichen Abständen Aussparungen ausgeschnitten.To reduce weight in mechanically weakly loaded webs and straps cutouts are also cut at equal intervals.
