DE19834395C2 - Projectile head - Google Patents

Description

The invention relates to a projectile head of a wing stabilizer based training floor, as it is characterized by the characteristics of the waiter concept of claim 1 is defined.

The problem arises in particular with tank ammunition, unused stocks of live ammunition a certain time (e.g. after the warranty expires time) into appropriate ammunition for training purposes work. In the case of so-called multi-purpose combat ammunition (MZ ammunition), such as those made from 120 mm Panzerkano NEN is fired, it is known to use the explosives with the Hollow charge insert from the shell of the projectile head too remove and approximately the same with an inert packing Mass to replace. As a packing z. B. Magnesium chloride / oxide used.

The disadvantage of such known projectile heads under other that both their reworking in practice floors as their later disposal is also very complex.  

From the unpublished German published application DE 198 06 958 A1 is also a projectile head mentioned at the beginning ten type known, in which a metal tube as filler ver is used, which is on the front and rear of the ent speaking side walls of the projectile shell non-positively supports.

The disadvantage of this known projectile head is, above all, that the fixation within the packing is relatively complex and is therefore expensive.

The present invention has for its object a Specify the projectile head for an MZ practice projectile which is on cost-effective way while maintaining the focus lay from a corresponding storey head of an MZ battle shot can be converted.

This task is characterized by the characteristics of the Part of claim 1 solved. Further advantageous Ausge Events of the invention disclose the subclaims.

Basically, the invention is based on the idea of the shell as an inert packing a cylindrical Arrange full body, which by means of axial fixation a screw on the rear wall of the shell is strengthened and its front end freely in the interior projecting space of the shell.

Using a full body is also an advantage fortunately achieved that the packing is sufficient Has material strength and thus the loads when Shooting the practice floor safely withstands.

In an advantageous embodiment of the invention  rear end of the preferably steel filler form-fitting to the corresponding contour of the rear adapted side wall of the shell. This is done on simple way in addition to the axial also a radial Fixation of the packing inside the shell.

Further details and advantages of the invention emerge from the following embodiment explained with reference to a figure example.

The figure shows a longitudinal section through a bullet head designated with 1 according to the invention of an MZ exercise floor. The projectile head 1 comprises a caliber-like projectile casing 2 and a peg-shaped projectile tip 3 , which is connected via an extension 4 to the projectile casing 2 by means of a screw connection 5 . A cylindrical solid body made of steel is arranged in the projectile casing 2 (for weight compensation) as an inert filler 6 .

For the axial fixation of the filler 6 on the projectile casing 2 , a fastening screw 7 is provided, the thread shaft 8 of which projects through a bore 9 of the rear wall 10 of the projectile casing 2 and is screwed into an internal thread 12 arranged in the rear end 11 of the filler body 6 . This screw connection is additionally secured by an adhesive layer 13 .

For the radial fixation of the filler body 6 , the inside 14 of the rear wall 10 of the projectile shell 2 has a truncated cone contour to which the rear end 11 of the filler body 6 is positively adapted. In addition, a center-shaped extension 15 is provided for centering the filling body 6 , which engages in a form-fitting manner in the bore 9 provided for carrying out the fastening screw 7 . For this purpose, the bore 9 on its side facing the packing 6 is correspondingly enlarged.

The front end 16 of the filler body 6 projects freely into the interior 17 of the shell 2 . The length 18 and the diameter 19 of the filler 6 are selected such that the center of gravity of the projectile head 1 corresponds essentially to the center of gravity of the projectile head of the corresponding MZ combat projectile.
