The invention relates to an explosive device for missiles for combating armored targets.

To combat armored targets, it is known to use shaped charges that consist of an explosive body conical recess exist. In the recess there is a conical metal insert, which is used in the Ignition of the shaped charge creates a sharply focused beam of shaped charge, which is made up of very fast but small Particles. The high penetration efficiency of shaped charge projectiles goes back to the strong concentration of the shaped charge beam. This bundling can be done with modern Armoring are disrupted, so that shaped charge projectiles are rendered harmless with appropriate measures can.

For combating armored targets, balancing projectiles are also known, the penetration capacity of which is lower, but which act with a greater mass on the goal.

The object of the invention is to provide an explosive device of the initially mentioned to create mentioned type, which combines the advantages of shaped charges and balancing projectiles in equal measure and the effects of which cannot be eliminated with the usual defense measures.

To solve this problem, the invention provides that at least two on their back have a layer of explosives load-bearing plates can be fixed in a functional point in which they are adjacent to one another Form angles of less than 180 and that one detonates the explosives of the two plates at the same time Ignition device is provided.

Flat metal plates can be accelerated to speeds of approx. 2000 m / s by covering one of the flat sides with explosives. The direction of flight, however, runs almost in the direction of the surface normal of the plate, that is, in a direction in which the plate cannot develop any penetrating force. The difficulty, which consists in the fact that the flight direction of a plate accelerated in this way does not run parallel to the plate surface, but almost perpendicular to it, is eliminated according to the invention in that two plates are verv / ends, which are symmetrical to the intended flight direction, under one Angle of slightly less than 90 inclined towards this, are arranged. Upon detonation of the Sprengstof a welding of the two plates into a single plate for layers on the plate back sides occurs, similar to the projectile formation of flat cone shaped charges, which 'moves like an excess length projectile at high speed in the direction of the symmetry axis of the plate arrangement. The plates can expediently be designed as flat rods which, when the layers of explosives detonate, fold against each other and move towards the target like an extra-long bullet fired from a cannon.

The plates or flat bars can in an advantageous development of the invention be connected to one another by a hinge device that allows the panels to be opened from a position in which the plates are arranged essentially parallel to one another into the functional position enables. This makes it easier to attach the explosive device to a warhead of the usual caliber. The plates e.n the warhead can be unfolded like an umbrella before they detonate will. In this case, a device can be provided which allows the panels to be opened at a predetermined distance from the target surface automatically.

An explosive device can also contain several pairs of plates, the individual plates of which are opposite one another and are arranged in the manner of the struts of an umbrella. With simultaneous detonation of the explosive layers of all Plates create a sharply bundled structure with a large mass in the direction of the axis of symmetry. Preferably elongated, rod-shaped plates are used.

The explosive device can either be in front of the engine compartment or along the outside of the engine compartment. For existing engines that require the attachment allow the explosive device, the plates or flat bars can have a length of about 75 cm to 1 m.

The plates or flat bars are particularly advantageous in terms of the acceleration during welding Shape when they are slightly curved towards each other. The curvature can be cylindrical, for example. Furthermore is it is advisable to differentiate the thickness of the plates from

facing edges to be removed towards the outside.

In order to promote the perfect welding of the plates, they can be turned away from the explosive layer Side wear a layer of compressible material. This layer hinders that which takes place with great force The panels do not hit against each other, but prevent one panel from sliding off the other.

For the same purpose, the panels can be attached to the explosive layer facing away from the side profile structures, for example in the form of teeth.

The outer surface of the explosive layer can with regard to both on the mechanical protection and on a flawless sequence of the detonation with a dam be provided with a thin sheet. In order to avoid losses at the edge of the plate, it is also useful if the spring material layers overlap the edges of the panels.

It may be useful to use two explosives with different detonation rates to make the acceleration process more economical, e.g. by generating a so-called "pulling wave" will.

In order to prevent the possibility that the extra-long projectile produced by explosive physics is disturbed by allowing it to penetrate a change of direction is imposed, it is also proposed that the plates or flat bars loosely side by side to subdivide set sections and to reunite them by means of a relatively loose connection.

then holds a series of short impact projectiles instead of a single continuous stick projectile in which a fault triggered on a single balancing projectile is not transferred to the other balancing projectiles.

A suitable choice of explosives occupancy can also be used achieve that in this sequence of small bullets the following is a little slower than the previous one when the explosive layer on the sections each plate decreases by a small amount from section to section.

In the following, some exemplary embodiments of the invention are explained in more detail with reference to the figures.

The explosive device shown in Figure 1 consists of two plates in the form of flat bars 10, 11 made of metal and push against each other with their front sides. The backs of the plates 10, 11 are each covered with an explosive layer 12, 13 occupied. Grab the layers of explosives the plate edges.

The plates 10, 11 close an angle of somewhat less than 180 °. During the detonation, the explosive layers 12, 13 are detonated at the point 14 at which the neighboring Front sides of the panels butt against each other.

By 'ie outward progressive explosion of explosives layers 12, 13, the plates 10, 11 are each accelerated almost perpendicular to the plane of the plate. You come across it against each other and are along the central plane 15 with each other welded. This creates an extra-long storey that moves at high speed along the axis of symmetry 15 moves.

In the embodiment shown in Figure 2, the rod-shaped plates 101, 111 are slightly curved cylindrically and their strength decreases towards the edge. The rods 101 and 111 also have an explosive on their back layer 12, 13. The behavior of this explosive device when detonated is similar to that of the explosive device according to Figure 1.

In the embodiment shown in Figure 3, the plates 102 and 112 have on the forward facing surfaces Profiles 16, 17, for example in the form of teeth, corrugations, Waves or the like. These profiles mean that the welding of the detonation is continuously gec; en-

plates pressed together is favored.

In FIG. 4, an embodiment is shown in which the plates 103 and 104 also consist of flat rods which, however, are divided into individual length sections 18, 19, 20. These length sections 18, 19, 20 are loosely attached to one another. When the explosive layer is detonated, the inner length sections 18 are continuously pressed against one another and welded to one another. Independently of this, the middle longitudinal sections 19 are also welded to one another and, in turn, independently of this, finally the outer longitudinal sections 20. In the present exemplary embodiment, this results in 3 mutually independent balancing projectiles which hit the same point on the target shortly after one another. The subdivision of the plates has the advantage that irregularities in the detonation do not affect the function of the entire explosive device, but only the relevant pair of length sections. So that the individual pairs of length sections unite separately from one another, the explosive layers 12, 13, which are also ^{subdivided according to the length sections 1} S, 19, 20, continuously decrease, so that the following is always a little slower in the sequence of the individual balancing projectiles is than the previous one.

In Figure 5, the attachment of the explosive device, generally designated 21, to the front end of a Engine chamber 22 is shown. The two plates 10, 11 of the explosive device 21 are connected via a hinge device 23 connected to each other so that they lie flat against each other

can be laid. Shortly before the goal, the joint device works 23 automatically, the plates 10, 11 spreading apart according to FIG. 1 and the functional position take in.
