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.

First claim

What is claimed is:

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.

2. The test and/or practice ammunition according to claim 1 , wherein the blast point and/or the target is programmable in the electronic fuze controller.

3. The test and/or practice ammunition according to claim 2 , wherein when the blast point and/or the target is detected by the electronic fuze controller, ignition is triggered.

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.

10. The test and/or practice ammunition according to claim 8 , wherein the separation point is arranged between a projectile base and the projectile ogive.
