EP1508767A1 - Projectile head for training ammunition - Google Patents

Abstract

The practice projectile (1) for a practice cartridge, e.g. for a 120 mm tank gun, is of the same caliber as combat ammunition. The cartridge (3) for the propellant, also in the full-size caliber, has an integrated projectile base (4) with a projecting extension (8) to fit within a recess (11) in the projectile. The extension has an open end (9), and contains the combat shell detonator (10). The practice projectile has an inner limit stop (13) within the recess at the end towards the propellant, to prevent the projecting detonator unit entering fully into the base recess.

Description

The invention relates to a projectile head for a practice cartridge with the in the preamble of claim 1 specified characteristics.

From DE 42 02 780 A1 it is already known, large-caliber multi-purpose cartridges (MZ cartridge), as they are fired, for example, from 120 mm tank cannons, modular build. Such a modular structure has, among other things, the advantage that even before Place (i.e., immediately prior to use of the cartridge) can be decided whether a practice bullet or a caliber-like battle floor is to be fired.

For this reason, for the practice and combat cartridge the same drive part used, which also has a connectable with two bullet heads projectile tail section includes. To connect the drive part and the respective projectile head protrudes projectile head side from the drive part of a peg-shaped extension of the projectile tail section out, which screwed into a corresponding receptacle of the projectile head becomes. Before screwing together the drive part and the warhead must, however, usually a warhead detonator in a bullet head open Recess of the peg-shaped extension of the projectile tail section introduced become.

It has now been found that, for example, in a Umlaborierung a battle cartridge In a practice cartridge on site easily forget the removal of the warhead detonator can be, so that the then missed practice cartridge nor the warhead detonator contains, resulting in an undesirable endangerment of the practice floor later Persons and their environment can lead.

The invention is based on the object, a projectile head for a practice cartridge of specify the type mentioned, the only with a drive member for forming the Practice cartridge is connected, if it is ensured that in the drive part no Warhead detonator is located.

This object is achieved by the features of claim 1. Further, Particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea of the projectile head of the exercise cartridge on its side facing the drive part with a into the interior of the To provide recording extending stop, such that when existing warhead detonator this when connecting drive part and projectile head against the stop abuts and prevents the extension of the projectile tail section their final position in the Recording of the projectile head reached.

Particularly simple is the stop mountable when it is pin-shaped and extends perpendicular to the longitudinal axis of the projectile head through the receptacle.

If a screw connection is provided between projectile head and drive part, It has proven to be particularly advantageous if in the presence of a warhead detonator this encounters so early against the stop that the threads of the Components can not touch and screwing the drive part and projectile head therefore not possible.

If the projectile head carries a guide tape on the back, it has to be useful proved when the pin-shaped stop below the guide belt in or through the receptacle extends therethrough and at least one up to the guide band extending bore in the projectile head wall is guided laterally. Such an arrangement has the advantage that already ensured during the production of the training projectile that there actually is an attack. Otherwise, at the Injection molding of the guide band corresponding plastic through the bore of the projectile head wall get into the recording and form no leadership tape. Furthermore The stop is fixed by the guide band.

To ensure a quick assembly of the pin-shaped projection in the projectile head, It has also proven to be advantageous to provide the pin with a headboard, which within a directly adjacent to the guide band extended bore is arranged, wherein the length of the pin is chosen such that its the head part opposite end engages in a blind hole of the projectile head wall.

The invention thus the reliability of the exercise cartridge against false Handling to a considerable extent compared to known comparable practice cartridges increases and at the same time a pre-control function of the subsequent reliability already achieved during manufacture.

Further details and advantages of the invention will become apparent from the following with reference to figures explained embodiments. Show it:

Fig.1 longitudinal sections of a projectile head according to the invention and a drive member with bullet head side arranged warhead igniter;

Figure 2 is a view corresponding to Figure 1 in an attempt to connect the projectile head and the drive member together, and

3 a consisting of drive part and projectile projectile training cartridge.

In Fig.1, 1 with a projectile head for a practice cartridge 2 (Figure 3) and with 3 a drive part with an integrated, known per se projectile tail section 4 of the corresponding Exercise projectile 5 called. The arranged from a shaft part 6 with it Folding wings 7 existing projectile tail section 4 of the training projectile 5 has bullet head side a provided with an external thread peg-shaped extension 8. In the pin-shaped extension 8 is a front side open recess 9, in which a warhead detonator 10 is arranged.

The trained as a hollow body projectile head 1 has the rear side with a thread provided receptacle 11 for the peg-shaped extension 8 of the drive part 3 and is provided on the outside with a guide strip 12.

According to the invention, the projectile head 1 on its the drive part 3 facing Side a perpendicular to the longitudinal axis 21 of the projectile head 1 completely through the Recording 11 extending pin-shaped stop 13. This stop 13 points from the rear end face 14 of the projectile head 1 a distance 15, which is selected is that the stop 13 when connecting drive part 3 and projectile head. 1 (Fig.2) abuts against the front end face 16 of the warhead igniter 10 before the threads the components can touch, so that screwing of drive part 3 and projectile head 1 is not possible.

As can be seen in FIGS. 1-3, the pin-shaped stop 13 is located in the area below the guide band 12 of the projectile head 1 and relies on his one Side over a head portion 17 in a directly below the guide belt 12 is arranged extended bore 18 in the projectile head wall 19 from. On his headboard 17 opposite side, the stop 13 extends into a blind hole 20th the projectile head wall 19.

Of course, the invention is not limited to the embodiment described above limited. Thus, the stop does not necessarily have to be pin-shaped but may e.g. also have a tab-like shape.
