Abstract

A cartridge comprises a sleeve (3) and a submunition member (6) containing a carrier (4) which has a sleeve (5) with a front guide (8) and a rear guide (11). The latter has a rigid fin (20) which is flat on the projectile sleeve when folded down, and protected by a cover (12) which has at least one opening in its base. A hollow area is located between the cover base and the projectile base.

Description

The invention relates to a cartridge with a cartridge case and a submunition body containing bullet, which is a shell with a front guide and a tail arranged tail and includes the rear through a floor floor is closed.

When using tank ammunition to combat behind a cover be sensitive targets it is known to use the projectile as a carrier projectile for several submuniti to educate the body. The submunitions are then over the respective target offers ejected and spread over a relatively large area. With the well-known Pan However, ammunition is usually spin-stabilized carrier bullets.

In the case of armored ammunition that can be fired from smooth-bore cannons, the applicant is aware of this rin the use of such projectiles has not become known. there should play an essential role in this ammunition that the projectiles to the Flugsta bilization need a tail unit on the rear side, which is relatively far into that with propellant Cartridge sleeve filled with powder sticks out - with regard to the specified dimensions solutions of the respective cartridge - the accommodation of only a relatively small number of Allows submunitions.

DE 36 18 958 C1 already discloses a carrier projectile which can be closed by means of artillery known to be ejected from the submunition projectiles over a target area, wel che tail units with deployable wings, which in the folded state  are arranged flat on the outside around the projectile body. The support themselves Wings first off the inner wall of the main storey and unfold as soon as that respective submunition storey is pushed out of the carrier storey.

The invention has for its object a Pa from smooth barrel cannons trone with stabilizer stabilized carrier floor to indicate which, in relation to the front given dimensions of the cartridge, the largest possible volume for accommodation of submunitions.

This object is solved by the features of claim 1. More beneficial Embodiments of the invention disclose the subclaims.

Essentially, the invention is based on the idea of the rear of the carrier floor to arrange a tail unit with deployable wings, with the wings together folded state to be protected by a pot-shaped cover. The cover has at least one opening in its bottom, so that when the cartridge is fired through the opening into the interior of the floor propellant gases Generate pressure that is large enough to leave the cup-shaped cover after leaving the To blow off the gun barrel at the rear.

In order to accelerate the release of the cover, in one embodiment the Invention provided to insert a valve in the opening of the cup-shaped cover. The cover can be made from tempered steel, from a high-strength aluminum alloy or made of fiberglass-wrapped plastic (cross windings).

For example, a winder can be used as the tail unit.

The wings of the tail unit can be inclined in their unfolded position have, during the flight of the carrier projectile to a rotation of the Trägerge shot around its longitudinal axis and thus to a swirl stabilization from the carrier projectile ejected submunition leads.  

Another particularly advantageous possibility of swirl stabilization of the submuniti To reach the body, the carrier floor is in the area of its front fue tion with oblique groove-shaped recesses.

Further details and advantages of the invention will become apparent from the following exemplary embodiments explained by figures. Show it:

Figure 1 shows a longitudinal section through a cartridge according to the invention with a cartridge case and support projectile.

Fig. 2 is an enlarged view of the section marked II in Fig. 1 and

Fig. 3 is an enlarged view of the carrier projectile with unfolded wings of the cartridge shown in Fig. 1.

In Fig. 1, 1 denotes a cartridge which consists of a cartridge case 3 filled with propellant powder 2 and a carrier projectile 4 fastened to the cartridge case on the front side.

The carrier projectile 4 has a projectile shell 5 , which closes six submunitions 6 around and is closed on the back by an inwardly curved floor 7 . The shell 5 is provided on the outside with both a front and a rear guide (guide band) 8 , 9 . In addition, a winding guide 11 is arranged at the rear in a corresponding recess 10 ( FIG. 3) of the projectile casing 5 , which is protected by a pot-shaped cover 12 made of steel.

The cup-shaped cover 12 is non-positively connected to the projectile casing 5 via a shear pin 14 ( FIG. 2). In addition, the cover 12 has an opening 16 in its base 15 .

The carrier floor 4 has 8 oblique nu ten-shaped recesses 17 in the region of its front guide.

If the cartridge 1 is in the cartridge chamber of a corresponding weapon (not shown) and the trigger of the weapon is actuated, the propellant charge powder 2 is ignited and presses against the bottom 15 of the cup-shaped cover 12 on the rear side. Here ge long through the opening 16 propellant gases in the through the floor 15 and the Ge floor 7 formed cavity 19th

As soon as the carrier projectile 4 has left the weapon barrel, the propellant charge gases located in the cavity 19 push the cup-shaped cover 12 backwards, so that the shear pin 14 is sheared off and the cover 12 is pressed away from the projectile 4 . The wings 20 of the tail unit 11 then unfold ( FIG. 3).

Due to the inclined groove-shaped recesses 17 in the area of the front guide 8 of the support projectile 4 , this performs a rotation about its longitudinal axis 18 . This swirl is transferred to the submunitions 6 , so that after ejection over the target area, the respective central axis of the submunitions 6 in the stable and defined position, which they already had on the floor, is maintained after leaving the gusset 4 .

The invention is of course not limited to the embodiment described above, for example. For example, the pot-shaped cover 12 can be connected to the shell sleeve 5 instead of a shear bolt also by means of a fine thread or an adhesive connection.

Furthermore, the cover relative to the submunitions enclosing Ge shell casing axially slidably arranged and also z. B. be connected via a shear bolt to the projectile casing, so that the cover is initially moved somewhat to the projectile tip 13 in the Waf fen pipe by the gas pressure occurring during the firing of the weapon barrel and thereby removes the positive or non-positive connection between the cover and the projectile casing. The actual blasting off of the cover outside the weapon barrel then takes place as in the first embodiment described above, for example.
