Description

The invention relates to a weapon system with a weapon barrel weapon and electronics for production of directional signals for a directional system connected to the weapon.

Whether one with a weapon system, e.g. a battle tank, missed Projectile actually hits a target depends on a number of different influencing factors. Especially the individual shape of the bending line of the tube core axis is an important factor. They can also for example due to wear or changes in the bending line time-changing pipe properties of the respective Weapon has a relatively large influence on the trajectory of the corresponding Have bullets.

As far as known by the applicant, such pipe properties and / or their changes so far in the determination the directional signals are not taken into account.

The present invention has for its object a To specify the weapon system at which the current weapon or Pipe properties of the gun barrel during the determination the directional signals can be taken into account in a simple manner the first hit probability of the weapon system (e.g. of every main battle tank of a main battle tank fleet).

This object is solved by the features of claim 1. Disclose further advantageous refinements of the invention the subclaims.

Essentially, the invention is based on the idea that weapon-specific data assigned to a weapon Save the chip card and use a chip card reader on the corresponding one to determine the Directional signals required electronics (usually the fire control computer) transferred to. The weapon-specific data updated on the chip card at predetermined intervals.

In an advantageous embodiment of the invention the current weapon-specific data (e.g. wear and tear of the gun barrel etc.) either by the fire control computer or through the smart card reader with the fire control computer (e.g. from the number of shots, the pipe temperature etc.) determined and after each shot or after a sequence of shots over the chip card reader, which also has a writing unit, transferred to the chip card. A separate update of the data of the respective chip card can be omitted in these cases. In addition, the Current pipe properties to determine the directional signals available before each shot, making a significant Combat strength increase is easily achieved.

Another advantage of the weapon system according to the invention is in that tampering with the weapon systems unauthorized third parties can be prevented in a simple manner. Because only if the chip card reader that of the respective Gun system associated chip card identified and the corresponding weapon-specific data on the fire control computer can be transferred, an activation of the weapon respectively. As a rule, the chip card should only be used by the respective commander of the weapon system (or the main battle tank) managed (commander chip card) so that safe and intended use of the corresponding Weapon system is ensured.

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

In the figure, 1 is a schematically illustrated weapon system a main battle tank, which essentially consists of a weapon 2 with weapon barrel 3 and a fire control computer 4 with microprocessor 5 and buffer 6 for generating Alignment signals for a straightening system connected to the weapon 2 7 exists. A first output of the fire control computer 4 is therefore connected to the straightening system 7 via a line 8.

For entering target-relevant data in the fire control computer 4 is also one by the gunner or the commander of the tank-operated control unit 10 is provided.

According to the fire control computer 4 is a chip card reader 11 upstream, in the shaft 12 one of the Gun 2 associated chip card 13 with memory 14 insertable is. The reader 11 contains one for reasons of clarity Electronic circuit device not shown in detail for reading and, if necessary, overwriting the one stored in the memory 14 of the chip card 13 weapon-specific data including a microprocessor 15 and a memory 16. In addition, the chip card reader contains 11 a clock 17, whose function below is explained in more detail.

It is preferably the case in the memory 14 of FIG Chip card 13 filed data to data the pipe statics (e.g. the bending line of the tube core axis), the state of wear as well as the total number of shots of the corresponding gun barrel affect.

The following is the operation of the invention Gun system received:

After the battle tank including the Fire control computer 4 and the peripheral devices Commander of the tank put the chip card 13 in the slot 12 of the chip card reader 11. Only from this point on the weapon is activated. The reader reads the on the Memory 14 stores data, evaluates it and stores them in memory 16. The fire control computer calls from there 4 to determine directional signals.

After entering appropriate target-specific data (target distance) The fire control computer calculates the control unit 10 4 the directional signals (according to height and side) and gives these signals via line 8 to the straightening system 7.

If the commander now gives e.g. via a firing unit 18 den Firing order, so if the coincidence condition is met the corresponding firing pulse via line 9 the breech of the weapon 2 and the corresponding ammunition unit ignited. At the same time, the fire control computer 4 informed about the firing by means of a line 9 ' and updates the data on the chip card 13 (e.g. total number of shots of the tube, firing frequency) by a writing unit 19th

With the help of the arranged in the chip card reader 11 Clock 17 are the data at predetermined time intervals read out again from the memory 14 of the chip card 13, in the reader 11 evaluated and updated to the fire control computer 4 passed. This ensures that the fire control computer 4 always the current data from the Receives chip card 13.

The invention is of course not based on the above described embodiment limited. For example the data preparation for after a shot data to be transferred to the memory of the chip card instead of a chip card reader Writing unit in the fire control computer. Furthermore can be used as a clock for reading the chip card an external clock or currently stored data the clock generator already present in the fire control computer be used.
