Definitions
- the invention relates to a warhead with an ignition device and a projectile-forming Charge.
- Such warheads have long been known and are for example in artillery ammunition, Rockets, but also in mines.
- This is the projectile-forming charge usually from a flat cone charge, i. a usually dammed explosive charge with frontal cavity seen in the main direction of action, in which a 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 a projectile results, which stabilized by a corresponding rear widening in his flight becomes.
- the invention is based on the object, a warhead of the type mentioned specify, with the projectile-forming charge, a projectile by explosive deformation is formed, which has a secondary performance in the target, not only larger is comparable to that of comparable projectile-forming charges KE ammunition.
- the invention is based essentially on the idea that the projectile not by the Effect of the detonation wave on a flat cone insert, but on a metal tube, preferably of steel, tungsten, tantalum or copper, to produce its axis of symmetry is arranged in the main direction of action of the projectile to be generated.
- the metal tube is at least in some areas of a dammed explosive charge surrounded so that the detonation wave after ignition of the explosive charge on the Metal tube acts that this with respect to the main direction of action from back to front compacted into a projectile and accelerated in the said direction.
- the metal tube inside with a liner tube lesser density preferably of aluminum or magnesium, is lined.
- a lower density substance within the tube is achieved that the obstacle to be penetrated is quasi “punched out” so that less total Energy is required for the drilling work and more energy for the acceleration the resulting particles are available (larger secondary effect).
- the Cavity of the metal tube with a powder, e.g. made of aluminum particles, filled in, the grain size of the powder should be between 0.3 mm and 5 mm.
- the warhead according to the invention can preferably be used in multi-purpose projectiles become. All you need to do this is to block the explosive charge as a splinter shell be educated. The explosive placed between the metal tube and the splinter shell then causes a much greater explosive effect than the comparable, with a flat cone insert provided multi-purpose projectiles.
- Fig. 1 denotes a stabilizer stabilized multi-purpose projectile, which rear side a hinged tail 2 and the front has a projectile body 3.
- Projectile body 3 comprises a projectile envelope 4 designed as a fragment envelope.
- the projectile casing 4 is located at the rear of an ignition device 5, to which in Direction of the axis of symmetry 6 of the projectile 1 on the front side a metal tube 7 made of steel with a deposit tube 8 made of aluminum connects. In this case, the axis of symmetry fall 6 of the projectile 1 and the symmetry axis 9 of the metal tube 7 together.
- the ignition device 5 and the metal tube 7 are rotationally symmetrical of an explosive charge 10, consisting of a plastic-bound explosive, surrounded. Besides that is between the ignition device 5 and the metal tube 7 a detonation shaft 18 is arranged (Fig.2).
- the multi-purpose projectile 1 is in the immediate vicinity of a to be combated armored target, e.g. by means of a spacer igniter, not shown, the Igniter 5 is activated, which in turn ignites the explosive charge 10. This creates highly stressed gases 11, which the metal tube 7 and the deposit tube therein 8 compact progressively from back to front. This ensures the detonation shaft 18 by deflection of the detonation wavefront for a symmetrical Compaction.
- the Detonationswellenfront marked 12 acts axially on the stepped Transition region 13 between the already compacted tube portion 14 and the still not compacted tube portion 15, so that the forming projectile simultaneously in Direction of the symmetry axes 6 and 9 is accelerated. This creates a relative long projectile of high speed and thus high kinetic energy, which the armored target and has an extremely large secondary performance.
- the likewise compacted liner tube causes above all a density gradient in the Penetrator and leads to an increase in the secondary effect.
- Figure 3 is removable, can be dispensed with the liner tube. This one has The result is that a homogeneous penetrator is formed.
- the invention is not limited to the embodiments described above limited.
- the projectile casing front thin-walled than the rest Be formed area of the projectile body or remain open there, so that the accelerated projectile exits through the projectile shell as unhindered as possible.
- the metal tube may be formed at its ends both open and closed. Open, it is especially formed when a granular substance is used, so that this is not “blown away”. Closed, however, it is especially trained, when a pipe is used as an insert.
