Description

DESCRIPTION

Practice ammunition and training system using the practice ammunition

The invention is concerned with the programmability of a test and practice ammunition or a test and practice cartridge and a training system that uses such a programmable practice ammunition.

The training and operation of a tank crew should be as realistic as possible. The associated costs and damage on the shooting ranges or training areas, on the other hand, should be as low as possible. To date, there has been no practice ammunition for programmable explosive ammunition that sufficiently fulfills both requirements. This leads to high costs, since a combat ammunition is also used for training purposes. This is accompanied by possible damage to the infrastructure of the shooting ranges and the training areas.

Another problem with the use of combat ammunition is the occurrence of possible unexploded ordnance. When combat ammunition is used, dangerous unexploded ordnance can occur despite the functional reliability achieved, which considerably disrupts training operations. In particular, these can represent a source of danger until they are destroyed.

From DE 10 201 1 107 960 B3 ammunition, in particular ver firable ammunition from handguns is known, which comprises a projectile shell having a projectile shell. Included in the projectile body is a charge that can preferably be exploded in the air. In order to ensure that the marking of an air detonation point or, if desired, an impact point of the projectile body in the target over a longer period of time is made clearly visible, it is proposed to use a marking substance for marking the air detonation point or the impact point. For this purpose, the shell comprises a centrally arranged cylindrical block with a cargo space containing a load. The cylindrical block has at least one pressure relief bore extending radially from the cargo space to the outer periphery of the cylindrical block. The outer periphery of the cylindrical container is from an annular container surrounded with the marking material. Before or during the firing of the practice ammunition, a time fuse arranged on the ground side in the ammunition is programmed such that the charge is ignited before the projectile body hits a target. The gas pressure acting on the charge ignites the container with the marking material and the shell casing. The marking material is applied from the projectile body. In addition, a bang and / or flash can be generated when the air detonation point is reached.

Here, the invention has the task of demonstrating a practice ammunition or a practice bullet, especially in the large caliber range, with which a training and practice operation, in particular a tank crew, can be carried out as realistically as possible.

This object is achieved by the features of patent claim 1. Claim 10 represents a training system. Advantageous designs can be found in the subclaims.

The invention is based on the idea of creating an inexpensive practice ammunition that can send out a signal at the target, which serves to signal a crew of a weapon system how good or bad the operation of the weapon system was, ie whether the shot was good and would have been precise.

For this purpose, the practice ammunition has electronics which are integrated in the practice floor and preferably have all the detonator functions of a live combat ammunition. This has the advantage that the operation of the weapon system by a tank crew can take place in exactly the same way as with a live combat ammunition, e.g. with HE combat ammunition.

After the practice ammunition has been fired, an impact on the practice floor at the target is detected, as with an original ignition system. This can be a ground hit or a hit on a target. This can be followed by the transmission of a signal to a stationary receiver or one that can be moved with the target in the target area or at the target. This can be, for example, a light signal, an infrared signal, a radio signal or another suitable electronic or optical signal as well as a color signal. This signal can obtain a signature or a representation of the effectiveness of the combat success for the crew. As an alternative or in addition, the target or rifle targets on the shooting range or the training area can, for example, be completely or partially folded over as a representation of the effect.

When choosing an air detonation point of the training ammunition at a predetermined or programmable target distance, the electronics in the training floor generate a signal for at least one receiver located at the predetermined (programmed) detonation point. At the location or position of the passing practice floor, which emits a signal, the at least one receiver knows the correct or incorrect position of the training projectile at the predetermined (programmed) “air detonation point” on the basis of the correct or deviating position of the transmitted signal. The at least one receiver itself can be stationary and / or movable. The at least one receiver is preferably located on the ground.

The signal emitted by the training floor can also be used to display an effect or a representation of the effects that are visible at the detonation point for the operation of the weapon system. This effect can be triggered by the at least one recipient.

In a further development of the invention, when the weapon system is operated correctly, a corresponding effect representation can be triggered in the target, which can be perceived by the crew as the target or target location. In particular, the correct position of the training floor in the air detonation point triggers a corresponding presentation of the effects for the pan crew, which the crew perceives as a "target being fought". The effect of a detonation can include can be realized with a suitable pyrotechnics.

If the target is not effectively combated by incorrect operation of the weapon system, an illustration of the effect can be dispensed with. The absence of an impact report then signals the crew to operate it incorrectly. Alternatively, however, a detonation display in the target area with, for example, a different coloring can also be undertaken. Based on the color differences between detonations with the correct or incorrect position, the crew can recognize whether the target was fought or a miss.

If an effect representation recognizable for the crew at the detonation point is taken over by the training floor, at least one receiver and a stationary effect representation can be dispensed with to simplify the shooting setup.

A practice ammunition is thus proposed, comprising at least one practice bullet with a projectile head and a drive. The practice floor can be programmed. For this purpose, at least one electronics in the form of a detonator replacement electronics and a signal transmitter are installed in the projectile head. Optionally, a representation of the effect can also be incorporated in the bullet head. The representation of the effects is preferably a pyrotechnics.

A light signal, an infrared signal, a radio signal or another suitable electronic or optical signal, including a color signal, can be emitted as a signature display via a signal transmitter. The effect display can optionally be initiated and deployed via the signal generator. The projectile itself should be provided with radial openings to enable the signature and, if applicable, the effects to be displayed.

The detonator replacement electronics preferably have all the functions of the electronics of a selectable or selected detonator variant of another combat cartridge. The drive also has at least one interface that is required for data transmission from a weapon system. In the drive there is also data transmission to the fuse replacement electronics in the projectile head.

The implementation of the invention is thus a programmable practice ammunition with an active representation of the effect in the target or target area.

The programmable practice ammunition itself contains only very small amounts of explosives. However, it can preferably also do without explosives.

The advantage of this programmable training cartridge is that the projectile contains no explosives, which prevents duds. Unused pyrotechnics in the training system can be dismantled after shooting and pose no danger. The programmable practice ammunition creates realistic practice with a presentation of the effects at the target or in the target area. Damage to the firing lanes and training areas are largely excluded and unexploded ordnance avoided. In addition, the costs of programmable practice ammunition are lower.

Furthermore, a training system is proposed for realistic practicing with a representation of the effects through the practice ammunition or the practice floor at the target or in the target area. The training system comprises at least one weapon system comprising at least one weapon barrel for firing the practice ammunition. The training system also has at least one receiver for receiving the signal from the signal generator of the projectile ammunition. A representation of the active charge can be deployed in the target area and / or at the destination. The representation of effects in the target area or at the target depends on the operation of the weapon system, right or wrong, can be displayed. The at least one interface of the drive is used for data transmission between the weapon system and the cartridge base.

The practice ammunition can also be used as test ammunition for the development of detonators of live ammunition.

Based on an embodiment with drawings, the invention will be explained in more detail who the. It shows:

1 is a sketchy representation of a training cartridge according to the invention,

2 is an illustration of a floor of the exercise cartridge from FIG. 1, 3 shows a sketch-like representation of an effective representation in the target,

Fig. 4 shows another sketchy representation of the effect.

Fig. 1 shows a practice ammunition or practice cartridge 1, which is programmable. The programmable practice cartridge 1 consists at least of a projectile 1 1 and a drive 2. The drive 2 consists of a cartridge base 3 and a cartridge case 8. A propellant charge in the cartridge case 8 is not shown in detail.

The practice floor 11 comprises at least one floor head 4, which is equipped with a detonator replacement electronics 5 and a signal transmitter 6. Optionally, a charge 7 can also be integrated in the projectile head 4 to show the effect. The active charge 7 can be a pyrotechnic. Such pyrotechnic sentences often work in the visible, in the infrared and / or in the millimeter wave range.

FIG. 2 shows the practice floor 11 after firing from a weapon barrel 10 'of a weapon system 10 (FIG. 3). The practice floor 1 1 is provided with radial bores (openings) 15 to enable the application of a signature by means of suitable electronic or optical signals and, if necessary, the active charge 7 to show the effects. The Exercise shot 1 1 shows swing-out or fold-out tail units 1 1 .1. However, the application is not limited to this type of projectile. Alternative training floors are also conceivable.

The drive 2 of the programmable practice ammunition 1 has at least one interface (not shown in detail). The interface is used for data transmission (programming) between at least one weapon barrel 10 'of the weapon system or weapon system 10 and the cartridge base 3 of the practice ammunition 1. In drive 2, the data is transferred to the fuse electronics 5 in the projectile head 4. The fuse electronics 5 preferably have all the functions of electronics of a selectable or selected fuse variant of another battle cartridge.

In the weapon system 10 (FIG. 3), the practice ammunition 1 is programmed in accordance with a target selection. The practice ammunition 1 is then fired and the practice projectile 1 1 leaves the weapon barrel 10 ′ of the weapon system 10.

3 and 4 show a raining system 100 or 100 'for training or a training operation of a tank crew with at least one weapon system 10.

When the selected and programmed “detonation point” 20 (FIG. 3) is reached, the igniter replacement electronics 5 emits a trigger signal to the signal generator 6. The trigger signal is programmed accordingly. The signal generator 6 optionally triggers the active charge 7 on the trajectory for displaying the effect on the trajectory and / or sends a signal to a stationary one and / or movable receiver 13 on the ground. It can be a light signal, an infrared signal, a radio signal or another suitable electronic or optical signal. A color signal is also conceivable. The at least one receiver 13 can trigger a corresponding signature representation, effect simulation or effect representation 14 on the ground from this signal.

When the effects of exercise floor 1 1 are shown on the trajectory, the location of the "explosive point" in target area 20 can be seen by the crew.

4, the signal transmitter 6 of the training floor 11 sends a signal to the one stationary and / or movable receiver 13 on the ground. The target impact 12 may be a ground impact or a target 12 target. The at least one receiver 13 can trigger a corresponding signature representation, effect simulation or effect representation 14 on the ground.

If an active charge 7 is introduced into the projectile head 4, the signal generator 6 can optionally trigger a signature or effect display at the target 12 via the practice projectile 11. In a presentation of effects by the practice floor 11 on or in the target 12, an illustration of the effects 14 and the at least one receiver 13 on the ground can be dispensed with.

On the basis of a representation of the effects 14 on the ground or in the air, an assessment of the effect in the target area 20 or at the goal 12 is also possible over a long distance by the crew. The different or different depictions of effects signal the crew a success or a miss.
