Abstract

The invention relates to a warhead with an ignition device (5) and a projectile-forming charge. DOLLAR A In order to achieve that in the projectile-forming charge a projectile is formed by explosive deformation, which has a high secondary performance in the target, the invention proposes to produce the projectile by the action of a detonation wave on a metal tube (7) whose axis of symmetry (9 ) is arranged in the main direction of the projectile. In this case, the metal tube (7) on the outside at least partially surrounded by a dammed explosive charge (10), so that the Detonationswellenfront (12) after ignition of the explosive charge (10) acts on the metal tube (7), that this with respect to the Hauptwirkrichtung compacted from back to front into a projectile and accelerated in the said direction.

Description

The The invention relates to a warhead with an ignition device and a projectile-forming charge.

such warheads have long been known and are in artillery ammunition, for example, Rockets, but also in mines. There is the projectile-forming Charge usually from a flat cone charge, i. a usually dammed explosive charge with frontal cavity seen in main direction of action, in the one cone-shaped Insert of e.g. Copper or soft iron is inserted. After ignition of the Explosive causes the detonation wave deformation of the insert, so that yourself a projectile results, which by a corresponding rear widening stabilized during his flight.

When disadvantageous it has resulted in the known warheads, that the projectile-forming charges although a high armor-piercing effect in terms of their permeability own that but unlike traditional KE bullets the generation of secondary fragments, which should make the tank crew incapacitated, relatively low and therefore is insufficient.

Of the Invention is based on the object, a warhead of the above mentioned Specify type, in which with the projectile-forming charge a projectile is formed by explosive deformation, which in the target a secondary performance which is not only bigger as that of comparable projectile-forming charges, but also comparable KE ammunition.

These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.

The Invention is based essentially on the idea of the projectile not by the action of the detonation wave on a flat cone insert, but on a metal tube, preferably made of steel, tungsten, tantalum or copper, whose axis of symmetry in the main direction of the is arranged to be generated projectile.

The Metal tube is at least in some areas of a dammed explosive charge surrounded so that the Detonation wave after ignition of Explosive charge acts on the metal tube such that this with respect to the main direction of action from back to front to a Projectile compacted and accelerated in the said direction.

While the Compaction of the metal tube essentially by the orthogonal Component of the detonation wave is caused, the acceleration takes place of the resulting projectile to a high speed substantially by the axial component of the detonation wave, which mainly on the transition area between the already compacted and the not yet compacted Pipe section works.

When It has proven advantageous if the metal tube inside with a lower density liner tube, preferably of aluminum or magnesium, is lined. By using a substance lower density within the tube is achieved that to penetrating obstacle is virtually "punched out", so that in total less energy for the drilling work is needed and more energy for the acceleration the resulting particles are available (larger secondary effect).

at a further advantageous embodiment of the invention provided that the cavity of the metal tube with a powder, e.g. made of aluminum particles, filled in, being the grain of the powder should be between 0.3 mm and 5 mm. By using of such a powder is achieved that by the variation of the bulk density the Kompaktierungsgrad is adjustable.

Of the Warhead according to the invention can preferably be used in multi-purpose projectiles. For this just needs the damming of Explosive charge as splinter shell be educated. The arranged between the metal tube and the splinter shell Explosives then causes a much greater explosive effect than at the comparable, provided with a flat cone insert multi-purpose projectiles.

Around a hindrance to the projectile produced by explosive deformation through the warhead casing to avoid, this points, in the main direction of the projectile seen, a smaller wall thickness on as in its remaining area or alternatively has an opening, the diameter of which is at least the diameter of the after explosive deformation corresponds to the resulting projectile.

Further Details and advantages of the invention will become apparent from the following explained with reference to figures Embodiments. Show it:

1 the longitudinal section of one as More projectile trained warhead according to the invention with a projectile-forming insert, the metal tube enclosing an additional liner tube;

2 an enlarged section of the in 1 shown warhead, in which only the projectile-forming charge is shown shortly after ignition;

3 a 2 corresponding view in which the projectile-forming charge includes a metal tube without liner tube and

4 a 3 corresponding view, in which there is a granular substance in the cavity of the metal tube.

In 1 is with 1 a stabilized stabilized multi-purpose projectile, which at the rear a folding tail 2 and on the front side a projectile body 3 having. The projectile body 3 comprises a projectile envelope designed as a projectile shell 4 ,

In the projectile shell 4 located at the rear of an ignition device 5 , in the direction of the axis of symmetry 6 of the projectile 1 on the front a metal tube 7 made of steel with a liner tube 8th made of aluminum. In this case, the axis of symmetry fall 6 of the projectile 1 and the axis of symmetry 9 of the metal pipe 7 together. The ignition device 5 and the metal tube 7 are rotationally symmetric of an explosive charge 10 , consisting of a plastic-bound explosive, surrounded. In addition, between the ignition device 5 and the metal tube 7 a detonation shaft link 18 arranged ( 2 ).

Subsequently, the process that leads to the formation of a projectile in the explosive deformation, using the 1 and 2 explained.

Is the multi-purpose projectile 1 in the immediate vicinity of an armored target to be combated, the ignition device, for example, by means of a distance fuze, not shown 5 activated, which in turn the explosive charge 10 ignites. This creates high-tension gases 11 which the metal pipe 7 and the deposit tube therein 8th compacting progressively from back to front. This ensures the detonation shaft 18 by deflection of the detonation wavefront for a symmetrical compaction.

With 12 characterized Detonationswellenfront acts axially on the stepped transition region 13 between the already compacted tube area 14 and the not yet compacted tube area 15 , so that the projectile forming at the same time in the direction of the axes of symmetry 6 and 9 is accelerated. This results in a relatively long projectile of high velocity and thus high kinetic energy, which breaks through the armored target and has an extraordinarily high secondary performance.

The also compacted liner tube causes above all a density gradient in the penetrator and leads to an increase the secondary effect.

Along with the formation of the projectile is also the splinter shell 4 of the projectile 1 destroys and causes a splinter rain in the vicinity of the target to be combated.

As 3 can be removed, can also be dispensed with the deposit tube. This has the consequence that a homogeneous penetrator arises.

When using a metal tube, in which the cavity 16 with a granular material 17 is filled ( 4 ), z. B. with aluminum particles of grain size 0.3 to 5 mm, it is achieved that by varying the bulk density of Kompaktierungsgrad is adjustable.

The Invention is self-evident not limited to the embodiments described above. So the projectile shell can thin-walled front be formed as in the remaining area of the projectile body or stay open there so that the accelerated projectile is as unhindered as possible exits through the projectile shell.

The Metal tube can be both open and closed at its ends be educated. Obviously, it is trained, especially if a grainy Substance is used so that these not "blown away." Closed On the other hand, it is mainly formed when a pipe as an insert is used.
