Abstract

It is proposed to make a cartridge or ammunition (1, 10) modular, d. That is, to equip the drive (3) with a defined interface (5) and to use this both for a base projectile head and for special novel projectile heads (9). The basic head can be used, for example, to practice on the existing exercise areas. If, on the other hand, the drive (3) is combined with a new projectile head (9), the requirements for growth potential or for use in various areas can be taken into account.

Description

The invention is concerned with a full-caliber practice cartridge or ammunition, especially in the caliber range of 120 mm, which is characterized in that it is to meet the different requirements, modular and thus in addition to their use as Üb-cartridge also for use in real operations - such as Mout missions - can be used.

Various training munitions, for example American full-caliber practice munitions - M831A1, the German - DM 18, the Israeli - M326 etc. are known from the prior art.

Due to different, sometimes conflicting requirements of the user, etc., the invention has the object to provide a new, inexpensive full-caliber (VK) practice cartridge, which makes it possible to respond to the different needs or uses can.

The object is achieved by the features of claim 1. Advantageous embodiments are the dependent claims.

The invention is based on the idea of modular execution of the cartridge or ammunition, d. h. to equip the drive with a defined interface, to use this for both a basement head and for special novel projectile heads. With the base head can be practiced for example on the existing practice sites. If, on the other hand, the drive is combined with a new projectile head, the demands for growth potential or for use in various areas can be taken into account. In Mout missions there is also the demand for avoiding collateral damage. For this scenario, the novel projectile head should therefore, for example, work according to the well-known PE-LE principle, in which the decomposition of the projectile is done within or just behind the first target, such as a wall.

In addition to the use of the drive for other and other projectile heads, the appearance of the various full-caliber tank ammunition can be simulated by means of hoods detaching at the mouth. The replacement takes place z. B. by the dynamic pressure. Through the detachment process, the aerodynamically effective geometry of the multi-purpose ammunition comes into effect (same track properties). This allows the use of the existing MZ (multi-purpose ammunition) computer cards in the tanks.

The base floor is preferably made of an aluminum center pipe with a plastic seal. This can consist of a sprayed guide tape of a tried bullet. This offers the advantage of using the existing tool. Alternatively, however, this seal can also be pressed on as a ring or executed as a snap-on solution. On the center tube, a steel tip is screwed with the outer contour similar to a HE tip with a Teilogive, for example, which meets the demand for the appearance of the new HE-combat ammunition.

The rear part is connected by means of adapter elements - for example sleeve cap, threaded ring - with the drive components. Alternatively, plastic sleeve cover can snap into the rear part or be used in this, similar to the DE 10 2005 019 534 A1 , The tail section itself consists of a preferably easy-to-manufacture tailstock on which the existing MZ tail can be mounted. The MZ tail can also consist of a low-cost and imported extrusion. To realize a stable flight behavior of the projectile in the basic variant - air attack point approx. 0.5 caliber behind the projectile center of gravity - a Heckogive and a massive steel tip are provided. The modular concept and the use of existing (mass) parts allows a further cost reduction. The converted ammunition for ammunition can in turn continue to be fired by conventional weapons systems or weapons systems, such as the Leo 2.

Reference to an embodiment with drawing, the invention will be explained in more detail. It shows:

1 a basic version as a training ammunition,

2 the basic version of the cartridge 1 with growth potential for real applications.

In 1 is with 1 a cartridge marked as a base variant for a training ammunition. This consists of a cartridge case 2 that drive 3 (Ignition unit + propellant charge) includes. With 4 is a Übungsgeschosskopf shown, for example, from a shell 4.1 and a tip 8th consisting, via an interface 5 with the drive 3 connected is. For a simple connection a screw connection is provided here. Alternative attachments are also possible. A Heckogive 6 provides for the flow of a (metal) tail unit 7 (with powder shoes 7.3 ). This contour can in a simplest version by the vulcanization of rubber or by the injection of plastic on the cylindrical part 7.1 of tail shaft 7.2 be created. Through a steel point 8th can be the center of gravity of the projectile 4 be changed so that it can be moved further forward.

2 shows the same ammo 1 out 1 - but with a modification. This is the drive 3 a novel bullet head 9 put on, for ammunition 10 converted. In comparison to the bullet head 4 is the novel bullet head 9 from a contoured steel shell 11 and a non-contoured aluminum tip 12 (relative to the bullet head 4 ). Thus, in this embodiment, a bullet type is created according to the PELE principle. - Of course, other projectile head types can also be accessed via the interface 5 with the drive 3 get connected. These can be application heads as with target signature, with tear gas, with bang or dazzling effect, etc., with the drive 3 as well as the cartridge case 2 are adaptable.

Even with this novel bullet head 9 to achieve a stable flight behavior - with the same tail section 6 - is a bit 15 required in MZ-like geometry. This can be achieved by adapting the plastic hood (s) 13 in Teilogiven form at the extended MZ-like tip 15 is created (also with the other use of projectile heads). This hood (s) 13 has defined breaking points 14 on to ensure a quick detachment at the mouth (after exiting a gun barrel not shown). The rapid detachment is achieved by the dynamic pressure, which has been shown in practice that a multi-part hood 13 creates a good replacement.
