The present invention relates to training ammunition for recoilless anti-tank weapons from the type of bazooka, which is made from an outer shape of the sharp self-propelled projectile There is a visual bullet with a sub-caliber barrel for firing sub-caliber training ammunition, with the sham bullet is automatically ejected from the weapon after it has been fired.

In practice shooting, all processes should be as similar as possible to those in an emergency. the So sham bullets loaded with sub-caliber ammunition should largely replace the live bullets same and should be able to be loaded just like this. Furthermore, it is desirable if the sham bullet is automatically ejected from the weapon immediately after the practice shot, so it is ready for a new charging process.

In a known training bullet for a bazooka, this is achieved by the fact that when it is fired the recoil exerted by the sub-caliber ammunition on the sham bullet is used, eject this from the rear of the weapon. However, this procedure is firstly dangerous for possibly People standing behind the shooter and, secondly, the ejection of the sham bullet gives way is behind the processes in the practical case and is therefore undesirable. Finally lets The sham bullet in bazookas does not throw itself backwards, because the bullet head is known to be here is larger than the diameter of the barrel of the weapon.

Grenade launchers have a sham bullet with an insert barrel known that an additional charge to eject the mock bullet from the weapon having. Since the launcher tube is closed at the back, the projectile can of course only forward be ejected. For the solution of the problem on which the invention is based, it can be derived from this However, no suggestion can be found because these rear-closed weapons compared to recoil-free ones Weapons represent a completely different species. This not least in view of the fact that the practice shot with recoilless weapons that are in the hand should be held, should proceed as similar as possible to the sharp shot.

A closer approximation to the practical conditions is achieved according to the invention by that on the Scheingesehoss in a known manner an additional charge to be thrown out of the Weapon is provided in the firing direction, which is in a special case outside of the sham bullet and is attached behind this. That extra charge

at the same time provides the purpose of a German charge for the acoustic indication of the launch and thus serves an approximation of the impression to that when the live projectile is fired. By the arrangement Behind the bogus bullet, the external charge resembles that of the live bullet Propulsion charge.

According to a special feature of the invention, the special sleeve is used for the additional charge attached to the bottom plate of the sub-caliber cartridge. This puts the extra charge on one Sham bullet at the same time with a new sub-caliber load and without additional handles on that Sham floor attached.

According to the invention, the additional charge is through channels with the propellant charge of the sub-caliber ammunition in such a connection that it is ignited when the additional charge detonates, the firing devices of the weapon acting on the additional charge. The ignition of the training bullet can thus be carried out by the same devices caused, which also cause the ignition in an emergency, in particular by the side Shooting a charge fuse through the case wall.

The case of the additional charge expediently has a larger diameter than the lower caliber barrel of the training shooting device.

The invention is described below with reference to the embodiment shown by way of example in the drawing described in connection with a bazooka. Leave in a corresponding modification the features according to the invention also apply to other recoilless weapons, for example at a bazooka.

In the drawing is

F i g. 1 shows a longitudinal section through a bazooka with used sham bullet and sub-caliber ammunition and

F i g. 2 a opposite F i g. 1 on an enlarged scale Longitudinal section through a sub-caliber bullet with an attached case for the additional charge.

The launch weapon consists of a barrel as well as holding, actuating and aiming devices. In the The barrel is the sham bullet 2 with its shaft 3 inserted from the front. It is that in its exterior simulated sharp self-propelled bullet. It has a sub-caliber barrel 4 in its interior.

The sham bullet is loaded with a sub-caliber bullet 5 in a sub-caliber case 6. That The lower caliber bullet consists of the heavy head 7, which is made of plastic-coated metal can, from the shaft 8, which is as light as possible and can be made of wood or plastic, and the body 9. which can also be made of wood or plastic and is provided with guide vanes at Ϊ0. So long if the projectile is in the sleeve, the guide vanes made of elastic material lie against the body more or less tight. After being shot down, they unfold.

The sleeve 6 has a bottom 11. Above the bottom there is an external thread 12 This thread is used to fasten the case in the lower caliber barrel of the mock bullet. Of course you can in place of this thread another locking device step.

The case also contains the body 9 of the sub-caliber bullet between the latter and its bottom 11 especially the propellant charge 13, the compensation ring 14 and the drive ring 15, whose functions are known are.

A sleeve 17, which contains the additional charge 18, is attached to the bottom 11 of the sleeve 6. These Charge 18 consists of the powder set, the ring 19, the filling carrier 20 and the bottom disk 21. The The filling carrier has the well-known function of the so-called dam.

The additional charge 18 is located via the bore 22 in the cartridge base 11 with the propellant charge 13 in the sleeve 6 in connection. Through this hole, the propellant charge when firing the additional Charge ignited. The ignition of the additional charge takes place in the usual way, i.e. H. in the Way in which the charges sitting in the appropriate place are detonated with sharp bazookas. This is done, for example, by shooting in a charge detonator from the side through the case wall 17 through from the firing device indicated by dashed lines below the sleeve.

The charge can also be ignited by electrical means or any mechanical means to be brought.

Claims (4)

Patent claims: 1. Practice ammunition for recoilless anti-tank weapons of the bazooka type, the from a sham bullet with the outer shape of the sharp self-propelled bullet with a sub-caliber barrel for firing sub-caliber training ammunition, whereby the Sham bullet is automatically ejected from the weapon after being fired, characterized in that that in a known manner an additional charge (18) for hurling the sham bullet (2) out of the weapon (1) in the firing direction is provided, which is in a special sleeve (17) outside of the sham bullet (2) and is attached behind this. 2. Practice ammunition according to claim 1, characterized in that the special sleeve (17) on the bottom plate (11) of the sub-caliber cartridge (6) is attached. 3. Practice ammunition according to claim 1 and 2, characterized in that the additional charge (18) through channels (22) with the propellant charge (13) of the sub-caliber ammunition in such a connection stands that this is ignited when the additional charge (18) detonates, and that the Firing devices of the weapon act on the additional charge (18). 4. training ammunition according to claim 1 to 3, characterized in that the sleeve (17) of the additional Charge (18) has a larger diameter than the lower caliber barrel (4) of the sham bullet (2).
