Test and/or practice ammunition

Abstract

The invention relates to a test and/or practice ammunition having at least one projectile with a projectile head and a fin which can be found at the end of the projectile for example or a projectile with a projectile base and a projectile ogive. A cartridge shell is used to receive a drive and has a shell base, wherein an interface is attached in or on the shell base. The test and/or practice ammunition is characterized by a programmable fuze which is arranged in the projectile head or the projectile ogive. The projectile head/projectile ogive is equipped with at least one fuze amplifier and an electronic fuze system and optionally a separating charge.

Claims

1. A test and/or practice ammunition comprising: a cartridge shell with a drive received therein, and a communication interface attached to or accommodated in a shell base of the cartridge shell; and at least one projectile coupled to the cartridge shell, the at least one projectile with a projectile head or a projectile ogive, wherein: a programmable fuze is arranged in the projectile head or in the projectile ogive, said programmable fuze comprising a fuze amplifier and an electronic fuze controller in communication with the communication interface; the projectile further includes a periphery defining a cavity; a pyrotechnic configured to generate a visible signal, a separating charge, and an inert material for damming; the inert material is positioned within the cavity and surrounds the separating charge; and the electronic fuze controller is configured to receive data specific to a programmed air blast point or at/in a programmed target from the communication interface such that a data transmission between the communication interface and the electronic fuze controller is within the cartridge shell, and trigger the programmable fuze, such that the projectile separates into two or more parts, and the pyrotechnic and the separating charge are ignited, once the projectile has reached the programmed air blast point or at/in the programmed target.

4. The test and/or practice ammunition according to claim 1, wherein the cartridge shell includes a shell base, and wherein the communication interface is mounted in or on the shell base.

5. The test and/or practice ammunition according to claim 4, wherein the drive is configured to receive the data via the communication interface.

6. The test and/or practice ammunition according to claim 1, wherein the projectile comprises an inert mass.

7. The test and/or practice ammunition according to claim 1, wherein the visible signal is a light and/or smoke signal.

8. The test and/or practice ammunition according to claim 1, wherein the projectile includes at least one separation point.

9. The test and/or practice ammunition according to claim 8, wherein the separation point is arranged between a fin and the projectile head.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be explained in more detail in the drawings on the basis of one embodiment. In the drawings:

(2) FIG. 1 shows a programmable test and/or practice ammunition,

(3) FIG. 2 shows an internal structure of a projectile of the test and/or practice ammunition,

(4) FIG. 3 is a representation of an air blast point of the programmable test and/or practice ammunition,

(5) FIG. 4 is a representation of a target impact of the programmable test and/or practice ammunition.

DETAILED DESCRIPTION

(6) In FIG. 1, 1 denotes a test and/or practice ammunition (cartridge) which comprises a drive 2 and a projectile 11 with a projectile head 3. The drive 2 is accommodated in a cartridge shell 9 which has a shell base 7. In or on the shell base 7, an interface 20 (not shown in detail) is arranged that is used for data transmission between a weapon system 10 and the projectile head 3 (e.g., shown by dashed lines via the interface 20 and the drive 2). Data transmission within the drive 2, i.e. from the interface to the projectile head 3, is ensured.

(7) A programmable fuze 4 is arranged in the projectile head 3. The fuze 4 preferably comprises a fuze amplifier 5. The fuze amplifier serves to trigger a projectile separation at at least one separation point 17 (FIG. 2). The projectile head 3 can optionally have an additional separating charge 6 (FIG. 2). Furthermore, there is an electronic fuze system 14 in the projectile head 3, which can trigger the fuze 4. Furthermore, the projectile head 3 should have an inert material 8 (FIG. 2) for damming.

(8) In this embodiment, the projectile 11 has a fin 15 which can be folded out in this case, but is not limited to this embodiment. According to this embodiment, the fin 15 forms the at least one separation point 17 on/in the projectile 11.

(9) The function is explained in more detail with reference to FIGS. 3 and 4:

(10) In the weapon system 10, the fuze 4 is programmed in accordance with the target selection. The programming interface is the interface 20 contained in/on the shell base 7. The programmed data are then stored in the electronic fuze system 14. This can be a selected, programmed blast point 16 on a trajectory of the projectile 11.

(11) When the selected, programmed blast point 16 according to FIG. 3 is reached, the ignition is triggered by the electronic fuze system 14. When triggering the fuze 4, the at least one separation of the projectile 11 takes place. Even with a target impact 12 according to FIG. 4, for example on a target or a floor surface, the ignition is triggered by the electronic fuze system 14.

(12) The separation can be realized for example by separating the fin 15 from the projectile head 3 at the at least one separation point 17. At the same time, a visible light and/or smoke signal 13, for example, can be transmitted. By transmitting the visible light and/or smoke signal 13, the function of the fuze 4 can be detected or recognized. In addition, the incorrect or correct position of the programmed blast point 16 in the target area can also be recognized by an operator or a crew. A pyrotechnic used for this purpose is preferably introduced or arranged in the region of the at least one separation point 17.
