Weapon system with caseless ammunition

The invention relates to a weapon system with caseless ammunition according to the preamble of claim 1 and claim 11.

Such a system is known for example from EP 1 731 867 B1. The projectile and the propellant are each a separate project warehouse or

Associated with propellant charge bearings, which are aligned in firing position coaxial with the axis of the barrel of the weapon barrel.

From DE PS 15 78 101 it is known to move the projectile bearing and propellant bearings transversely to the gun barrel in opposite directions to each other, to twist or to pivot, to allow an increased firing order and to keep the heat absorption of the barrel as low as possible. Unlike a classic sleeve ammunition, in which the projectile is firmly connected to the sleeve containing the propellant charge, in case of a failure of the propellant charge, no automatic ejection of the propellant charge and of the projectile is possible.

Weapon systems with caseless ammunition were therefore previously disadvantaged in stoppages, insofar as it has come to this conditional use interruptions.

An object of the present invention is to further develop the weapon system according to the preamble of claim 1 such that even with stoppages further use of the weapon system without significant temporal impairments can be achieved.

This object is achieved by a weapon system according to claim 1. In this case, the projectile bearing at a certain time has a chamber which is in an unloading position, in which an ejection device for the projectile in the chamber can be activated, whereas a further chamber of the projectile bearing is reloadable, in particular in this movement position of the projectile bearing. The propellant charge bearing at a certain time has a chamber which is in an unloading position in which an ejection device for the propellant charge in the chamber can be activated, whereas the further chamber of the propellant charge can be reloaded, in particular in this movement position of the propellant charge bearing. As a result, a discharge of the relevant chamber and a loading of the other chamber of the projectile bearing and corresponding preferably also on

Propellant storage be made simultaneously, regardless of whether the relevant chamber is filled with a propellant failure or not. The invention makes it possible to dispense with an additional clocking step, ie an additional position of the bearings for the operation of the ejection devices and to increase the shot sequence even with failures. By the invention

Measure at the same time allows a simple structural design.

Preferably, the ejection device for the propellant charge bearing and preferably also for the projectile storage at each unloading position, d. H. with progressive clocking, automatically d. H. automatically activated.

In a simple way, the invention can be realized in that the projectile bearing and the propellant charge bearings are each rotatable about separate diametrically opposite to the axis of the axis A of the weapon barrel axes X and Y respectively.

Preferably, the axes X, Y and the axis of the axis A lie on a common plane, which extends in the weft direction.

In an advantageous manner, the idea according to the invention has at least two chambers each. Accordingly, the propellant charge bearing expediently has at least two chambers and the projectile storage at least two chambers. For weapons with a smaller caliber, such as a 20 mm cannon, a version with only two chambers in terms of dimensions and technical realization is particularly advantageous. The timing of the system depends on the number of chambers. In a two-chamber system, each bar corresponds to a 1/4 turn. The firing position is taken after every second clock.

The unloading of the propellant charge bearing, so the removal of a possibly present propellant charge failure and the loading of the projectile bearing is preferably carried out in opposite directions. Here, the two bearings rotate in opposite directions. This is favorable for targeted heat removal measures. But also a synchronous movement is possible.

Appropriately, the projectile is ejected opposite to the firing direction to the loading side. The resistance of projectile-related attacks or leadership bands must therefore not be overcome when ejecting.

In contrast, the propellant failure is preferably ejected in the weft direction, whereby the back side, d. H. rear seal is not damaged.

The activation of the ejection devices can expediently, depending on the rotational movement of the projectile bearing and propellant charge bearing, for example via suitable synchronization gear or other control means, such. B. scenes or the like, are controlled.

Furthermore, it is expediently provided that a projectile to be unloaded can be returned to a loading space for the projectiles during the respective unloading process of the projectile warehouse and possibly from there by a suitable device from the projectile

Loading space is ejected.

The ejection device for the projectile and the ejection device for the propellant are expediently respectively correspondingly positioned and axially movable Auswerfdome. Such Auswerfdorne can via suitable

Synchronization or synchronization gear or the like with the rotational movement of the projectile bearing and propellant charge are coupled. They therefore represent a structurally simple solution variant.

Another object of the present invention is to develop the weapon system according to the preamble of claim 11 such that the security of the weapon system is ensured even after prolonged firing. This object is achieved by a weapon system according to claim 11.

The conventional caseless ammunition weapon system according to the preamble of claim 11 comprises a weapon barrel, a single-chambered projectile bearing, and a single-chambered propellant charge bearing

Projectile bearing and propellant charge bearing to ensure a firing position in which one of the chambers of the projectile bearing and one of the chambers of the propellant charge bearing are coaxial with the axis of the barrel axis, are movable relative to the barrel. Such a weapon system can be operated, for example, shooting up. This is z. As with a gun or a rifle of the case. Here, the propellant charge is introduced into the combustion chamber before the trigger is actuated, for example by manual actuation of a loading device (eg carriage). This requires that the propellant charge is already positioned relatively long before the actual shot in the combustion chamber. In addition, the propellant remains in the combustion chamber in case of failure until manual unloading.

This long stay of the propellant charge in the combustion chamber (both before the shot as well as after a failure) can pose a security problem especially after a long shot sequence has already taken place. Namely, if the combustion chamber is already strongly heated by the previously fired shots, there is a risk that the located in the combustion chamber

Propellant ignited without firing intent. This may unintentionally be fired one or more shots, which can lead to serious accidents. A similar problem arises when the weapon system is used in zuzuschießenden operation. This is z. B. the case of a submachine gun or a machine gun. Here, although only when pressing the trigger the propellant charge the

Combustion chamber supplied and shortly thereafter triggered the firing pin, in the case of a failure, however, the propellant remains in the combustion chamber even in zuschießenden operation. After a long shot sequence with subsequently heated combustion chamber, there is also the danger here, in the case of a Zündversagers that a long time in the combustion chamber located propellant unintentionally ignited itself.

In particular, by the features of the characterizing part of claim 11, the security in the weapon system according to the invention is significantly improved in terms of the above-described Selbstentzündungsproblematik. Accordingly, the projectile storage is movable in one or more consecutive cycles, each of the cycles comprising the following positions in succession: a first position, in which one of the chambers of the projectile bearing is in a loading position in which a slide-in device for inserting a projectile into this chamber is activated, a second position in which this chamber of the projectile bearing is in the firing position, and a third position, in the this chamber of the projectile warehouse is in an unloading position in which an ejection device for

Ejecting the possibly still located in this chamber projectile from this chamber is activated. Further, the propellant charge bearing is movable in one or more consecutive cycles, wherein each of the cycles successively comprises the following positions: a first position in which one of the chambers of the propellant charge bearing is in a loading position, wherein an insertion device for inserting a propellant charge in this chamber can be activated, a second position in which this chamber of the propellant charge bearing is in the firing position, and a third position in which this chamber of the propellant charge bearing is in an unloading position, wherein an ejector for ejecting the possibly still located in this chamber propellant can be activated from this chamber.

In a weapon system designed in this way, it is advantageously ensured that every cycle which begins with the loading of a chamber of the projectile storage and a chamber of the propellant charge bearing is always completely passed through until the discharge, in particular of the chamber of the propellant charge storage, irrespective of when ( especially with an automatic weapon) the trigger is released and also regardless of whether in particular the last charged propellant is a failure or not. This can ensure that a propellant, which at a certain time in a chamber of

Propellant charge bearing (and thus in the combustion chamber) is introduced, dwells in each case only for a very short period of time in the combustion chamber. Either the charged propellant charge is intentionally ignited a short time later in the firing position, or expelled from its propellant charge chamber in case of failure of the propellant charge or interrupting the firing order. As a result, inadvertent ignition of a propellant charge can be prevented in all conceivable cases with high probability even when the propellant charge bearing is heated. As a result, the safety of the conventional weapon system according to the preamble of claim 11 is significantly improved.

Preferably, the projectile bearing is rotatably mounted about an associated axis. Furthermore, the propellant charge bearing is preferably also an associated axis rotatably mounted. Preferably, the two axes about which the projectile bearing and the propellant charge bearing are each mounted rotatably, in each case offset parallel to the axis of the weapon barrel. Due to this rotatable mounting of the projectile bearing and the propellant charge bearing arise in particular with respect to the alternative linear displacement of the projectile bearing and the

Propellant charge bearing inertial advantages. With a rotatable bearing, the weapon system need not work against the moment of inertia of the projectile bearing and the propellant charge bearing once the bearings are rotated. This advantage is not given in linear reciprocating pushability of the projectile bearing and the propellant charge bearing.

Preferably, externally driven synchronization means are provided with which, depending on the rotational movement and / or the angular position of the projectile bearing and / or the propellant charge bearing, the respective ejection device can be actuated. In foreign weapon systems one understands with weapon systems the property that mechanical

Processes in the weapon system occur independently of the forces resulting from the firing of a shot. The opposite form so-called self-propelled weapon systems in which the forces resulting from the shot are used, for example, for the loading of the next cartridge. Classic self-propelled weapon systems are z. B. pressure loader or recoil loader. By the

Third party drive the ejection device, in particular the propellant charge bearing, the ejection of possibly still located in the chamber propellant charge from the chamber automatically after releasing the trigger, without any forces of a firing process would be necessary for this ejection process. This is particularly advantageous if the last charged propellant, which is still beaten just before releasing the trigger, failed and can not be discharged by the now lacking firing forces. The externally driven synchronization means operate in this case in any case nor the ejector of the propellant charge bearing. Preferably, the externally driven synchronization means also ensure that after this conclusion of the last cycle no new cycle is started, so that no new propellant and no new projectile is inserted into one of the chambers of the propellant charge bearing and the projectile warehouse more.

According to a particularly preferred embodiment of the invention

Waffensystems the ejection devices are so time-shifted actuated to the insertion devices that penetration of the ejection devices in the Chambers only with a time delay for insertion of the insertion devices after rotation of the projectile bearing and / or the propellant charge bearing from the loading position to 3607n, so the nth part of 360 °, carried out in the unloading position, where n is the number of chambers of the projectile warehouse and / or the Number of chambers of the propellant charge bearing is. This time-shifted actuation availability of the ejection devices is preferably realized in that the ejection devices and the insertion devices are coupled together such that a movement of the insertion devices on the projectile warehouse and the propellant charge storage is connected to a preferably equal amount of movement of the ejection means of the projectile warehouse and the propellant storage , Accordingly, a movement of the insertion devices away from the projectile bearing and the propellant charge bearing is preferably associated with a preferably equal amount of movement of the ejection devices to the projectile warehouse and the propellant charge storage. In this case, the projectile bearing and the propellant charge bearing are preferably arranged between the insertion devices and the ejection devices.

This can be ensured in an advantageous manner that the ejection / ejection of Zündversagern can take place in the opposite direction to the insertion direction.

This time-shifted actuation of the ejection devices can be controlled by the synchronization means described above. The advantage of the time delay of the operation of the ejection devices and the coupling of the ejection devices and the insertion devices lies in the simple and trouble-free controllability of the loading and unloading process. Furthermore, the weapon system designed in this way is characterized by a very smooth running.

In general, the use of as many chambers in the propellant storage is advantageous because the energy input (at the same cadence, ie at the same firing frequency per unit time) in the propellant bearing is the lower, the more chambers are provided. The disadvantage, however, is that the residence time of the respective propellant charges in their

Chambers using many propellant charge chambers is longer, the more chambers are provided. The long residence time of the propellant charges in the propellant charge storage increases the risk of auto-ignition (cook-off). The invention thus faces the problem of two opposing tendencies, on the one hand to provide as many propellant charge chambers to heat the propellant charge bearing as little as possible, on the other hand provide as few Treibladungskammem to the residence time of the individual propellant charges in their chambers keep as low as possible. In the context of the present invention, following detailed studies of theoretical and experimental nature, it has been found that the optimum number n of the chambers of the propellant charge storage is equal to 2 (n = 2). For this case (n = 2) thus results in a time-delayed penetration of the ejection devices in the chambers after rotation of the projectile bearing and / or the

Propellant charge bearing from the loading position by 180 ° in the unloading position. Another advantage of the realization of the weapon system according to the invention with only 2 propellant charge chambers and only 2 projectile chambers is that in this configuration, the advantageous opposite rotation of the projectile bearing and the propellant charge bearing can be more easily realized as a rotation from the loading position to

180 ° clockwise both projectile warehouse and propellant storage to the same unloading position and the same position of the projectile chambers and the propellant charge chambers to each other as a rotation from the loading position by 180 ° counterclockwise. For this reason, if the number n of chambers is greater than 2, it is more advantageous if projectile bearings and

Turn the propellant charge bearing in the same direction. But even in the case of n = 2, the same direction rotating projectile warehouse and propellant storage is conceivable.

An expedient embodiment of the present invention will be explained in more detail with reference to drawing figures.

In the drawings, the same or similar reference numerals designate the same or similar parts. Show it:

Firing position,

Figs. FIGS. 5A-5L show a plurality of time-sequential snapshots of the preferred embodiment of the weapon system according to the invention for illustrating the functional sequence during a faulty cycle (with ignition failure).

The reference numeral 1 denotes a weapon barrel z. B. for a 20 mm rapid-fire cannon of a preferably automatically operated weapon system with sleeveless

Ammunition and high firing, for example for use in a tank,

Helicopter or the like. The weapon system includes a total of two

Chambers 3, 30 comprehensive projectile 2 for receiving in a supply or

A punch 8 serves to spend the exactly positioned in the insertion position projectile 6, for example, as shown in Fig. 1 B, to spend in the chamber 30 of the projectile carrier 2. In the loading space 1 1 is a plurality of stockpiled projectiles, which by means of a (not shown)

Feeding device in the insertion position for the subsequent chamber, z. B. 3, can be brought. The chamber 3 is in the timing shown in Fig. 2 in the unloading position.

The weapon system also includes an independent propellant charge bearing 4 with also two chambers 5, 50, in each of which a propellant charge 7 can be introduced. As can be seen from Fig. 1 B, the loading of the propellant charge bearing 4 is ensured via a located on the weft direction side punch 9. The in the

Loading space 12 located, stored propellant charges 7 are successively placed in the insertion position and the respective chamber (in Fig. 1 B of the chamber 50) of the propellant charge bearing 4 is supplied.

Both the propellant charge bearing 4 and the projectile bearing 2 are designed as a pivot bearing and are moved in opposite directions, for example. According to Fig. 1 A, the propellant charge bearing 4 about the axis of rotation Y counterclockwise and the Projectile bearing 2 is moved around the rotation axis X in a clockwise direction. As can be seen from FIG. 1A, the chamber 5 is being filled with a propellant charge 7 in the rotational position (timing) illustrated therein, while the chamber 30 of the projectile bearing 2 is being filled with the projectile 6.

In the middle, the position of the weapon barrel 1. In this rotational position, there is neither a chamber of the projectile bearing 2 nor a chamber of the propellant charge bearing 4 in alignment with the axis of the soul A of the weapon barrel. 1

Fig. 1 C shows the arrangement of each not in firing position chambers, namely the chambers 3, 30 of the projectile bearing 2 and the chambers 5, 50 of the propellant charge bearing 4 relative to the gun barrel. 1

The rotational movement of the projectile bearing 2 and propellant charge bearing 4 takes place in a 1/4 turn. As shown in Fig. 2, in the same rotational position via a first Auswerfdorn 13 which may possibly by ignition inhibition in the chamber 3 projectile 6 ejected preferably opposite to the firing direction, preferably from the projectile warehouse 2 in the loading space 11 back where it passes through a device (not shown) is discarded.

At the same time the possibly defective propellant charge 7 is ejected by the second Auswerfdorn 10 preferably in the weft direction from the chamber 50 of the propellant charge bearing 4, preferably in the loading space 12, where it is separated by a (also not shown) device.

The loading according to FIG. 1 and the unloading according to FIG. 2 take place after every second cycle, such that the ejection domes 10, 13 move into the relevant chambers, regardless of whether there is a projectile 6 or a propellant 7 in the respective chamber or not.

After loading or unloading as shown in FIG. 1 and 2, the projectile bearing 2 and propellant charge bearing 4 rotates by a 1/4 turn further into the position shown in Fig. 3 (firing position), in which the previously loaded chambers 30 and 50 in Alignment to the axis of the soul A of the barrel 1 lie. In this firing position or firing position, the previously loaded chambers 30 and 50 are thus coaxial to the axis of the barrel 1, or in other words, the chambers 30 and 50 are in alignment with the weapon barrel 1.

The control of Auswerfdorne 10, 13 can be effected by synchronization means 15 and / or coupling means 14 which actuate the Auswerfdorne 10 and 13 depending on the rotational movement and / or the angular position.

Figures 4A to 4L show first several temporally successive snapshots of a preferred embodiment of the invention

Weapon system for displaying the functional sequence during an undisturbed

Cycle (without ignition failure of a propellant charge). FIGS. 5A to 5L then show a plurality of temporally successive snapshots of the preferred embodiment of the weapon system according to the invention already shown in FIG. FIG. 5 serves to illustrate the functional sequence during a faulty cycle

(with ignition failure of a propellant charge).

4 and 5 each represent a complete cycle which comprises the three positions "loading position", "shooting position" and "unloading position." The operation of the weapon system according to the invention therefore represents any sequence of cycles according to FIG. or 5 dar.

In the same way as in FIGS. 1 to 3, the reference numeral 1 designates a weapon barrel of a weapon system, which is preferably operated automatically, with caseless ammunition and high firing order. The weapon system preferably includes two chambers

3, 30 projectile projectile 2 for receiving located in a storage or loading space 11 projectiles 6. An insertion device 8 is used to move the positioned in the insertion position projectile 6 in the chamber 3 of the projectile bearing 2 (see Figures 4A to 4C and Figure 5A to 5C). In the loading space 11 is a plurality of stockpiled projectiles 6, by means of a (not shown) feeding into the insertion position for the next chamber, z. B. 30, can be brought.

The weapon system also includes a propellant charge bearing 4 with a number of chambers 5, 50, in each of which a propellant charge 7 can be introduced. Preferably, the number of chambers 5, 50 of the propellant charge bearing 4 with the number of chambers 3,

30 of the projectile warehouse 2 match. In the present example of Figures 4 and 5 is Accordingly, the number of chambers 5, 50 of the propellant charge bearing 4 equal 2. The loading of the propellant charge bearing 4 is ensured by a slide-9. The stored in the loading space 12, stored propellant charges 7 are successively placed in the insertion position and the respective chamber (in Figures 4A to 4C or in Figures 5A to 5C: the chamber 5) of the propellant charge bearing 4 supplied. Both the propellant charge bearing 4 and the projectile bearing 2 are designed as a pivot bearing, which preferably rotate in opposite directions. By the opposite rotation of propellant bearing 4 and projectile bearing 2 a high degree of smoothness of the weapon system can be achieved. The reason for the increased smoothness is the mutual compensation of any imbalance of the propellant charge bearing 4 and the

Projectile bearing 2 and the mutual compensation of bearing forces, which act on the rotary bearings of the propellant charge bearing 4 and the projectile bearing 2. As can be seen from FIG. 4A, the propellant charge bearing 4 is mounted rotatably about the axis of rotation Y and the projectile bearing 2 is rotatably mounted about the axis of rotation X. The two axes X, Y are each arranged offset parallel to the axis of the axis A of the weapon barrel 1. The propellant charge bearing 4 and the projectile bearing 2 are disposed between the rear end of the weapon barrel 1 and the striker 77. The firing pin device 77 has a firing pin 777.

The trouble-free operation of the preferred embodiment of the weapon system will now be explained with reference to FIGS. 4A to 4L. FIGS. 4A to 4C show a first phase of the cycle in which the chamber 3 of the projectile bearing 2 is in a first position, namely a loading position. In this first position, the insertion device 8 for inserting a projectile 6 in this chamber 3 can be activated. Furthermore, the chamber is located in this first position

5 of the propellant charge storage 4 in the loading position, in which a slide-in device 9 for inserting a propellant charge 7 in this chamber 5 can be activated. FIGS. 4A to 4C show these two insertion processes for the projectile 6 and the propellant charge 7. In this case, the insertion device 8 for inserting the projectile 6 into the chamber 3 and the insertion device 9 for inserting the propellant charge 7 in the

Chamber 5 coupled together. Through this - preferably rigid - coupling between the two insertion devices 8, 9 can be achieved in a simple manner, a synchronous insertion of the projectile 6 and the propellant 7.

Figures 4D and 4E show the transition from the first position to a second one

Position, the firing position, as shown in Figures 4F and 4G. In the firing position are the chamber 3 of the projectile bearing 2 and the chamber 5 of Propellant charge bearing 4 in alignment with the weapon barrel 1. The transition between the first position and the second position is achieved by the preferably opposite rotation of the projectile bearing 2 and the propellant charge bearing 4 about their respective axes of rotation X, Y. In the firing position close the end faces of the gun barrel 1, the projectile bearing 2, the propellant charge bearing 4 and the

Firing pin device 77 preferably tight with each other to ensure the required pressure development upon ignition of the propellant charge 7. During the phase of rotation shown in FIGS. 4D and 4E, the insertion devices 8, 9 are preferably not moved or, at best, withdrawn a small distance from the maximum insertion position of FIG. 4C in order to ensure undisturbed rotation of the

Projectile 2 and the propellant charge bearing 4 to ensure.

In FIG. 4G, the firing pin device 77 is actuated in the firing position. In this case, the firing pin 777 strikes the in-chamber 5 propellant body 7, possibly also on a mounted on the propellant charge 7 Zündplättchen. The

Propellant charge 7 then explodes in the chamber 5 of the propellant charge bearing 4 and accelerates the projectile 6 located in the chamber 3, which is accelerated by the weapon barrel 1 in the direction of the target.

Figures 4H to 4J show the transition from the second position to a third

Position, the unloading position, as shown in Figures 4K and 4L. The transition from the second position to the third position is again by rotation of the projectile bearing 2 and the propellant charge bearing 4 about the associated axis X and Y. In the unloading ejection devices 13, 10 can be activated in the form of Auswerfdornen, which in the shortly before Retract filled chambers 3 and 4. The ejection devices 13, 10 are preferably always activated in this third position, that is, even if in the firing position previously the firing was successful and the chambers 3, 5 have been emptied. This allows safe and trouble-free operation regardless of the success or failure of the previous shooting attempt. Preferably, the

Ejecting devices 13, 10 coupled together. This has the advantage that a synchronization of the ejection process in the projectile chamber 3 and the propellant charge chamber 5 can be achieved in a simple manner. Furthermore, in particular the retraction of the ejection device 10 into the propellant charge chamber 5 also has a benefit in the case of a previously scheduled ignition of the propellant charge 7, namely one

Cleaning function of the propellant charge chamber 5. In particular by appropriate design of the end face of the ejection device 10 (eg with scrapers or Brushes) namely burn-off residues of the ignited propellant charge 7 can be removed from the propellant charge bearing 5.

With reference to FIGS. 5A to 5L, the disturbed functional sequence (with ignition failure) of the preferred embodiment of the weapon system will now be explained. This

Functional sequence is identical in FIGS. 5A to 5F to the trouble-free functional sequence, as illustrated in FIGS. 4A to 4F. In order to avoid repetition, the explanations to FIGS. 4A to 4F for the explanation of FIGS. 5A to 5F are referred to in full here. Representative of all other figures is in Figure 5A nor the optional use of a

Synchronization means 15 shown, with which depending on the rotational movement and / or the angular position of the projectile bearing 2 and / or the propellant charge bearing 4, the respective ejection device 10, 13 and / or the respective insertion device 8, 9 can be actuated. The synchronization means 15 preferably acts on the rotary shafts of the projectile bearing 2 and the propellant charge bearing 4 and on the

Insertion devices 8, 9 and the ejection devices 10, 13. In the case of a coupling of the insertion devices 8 and 9, the synchronization means 15 can also act on this coupling. In the case of a coupling of the ejection devices 10, 13, the synchronization means 15 can also act on this coupling. FIG. 5A also shows the possibility of the insertion devices 8, 9 with the

Ejecting devices 10, 13 to couple. This coupling 14 is preferably connected to the coupling between the insertion devices 8 and 9 and the coupling between the ejection devices 10 and 13. In the case of the use of such a coupling 14, the synchronization means 15 can also act directly on this coupling 14. The coupling 14 causes a movement of the insertion devices 8, 9 on the projectile bearing 2 and the propellant charge bearing 4 is connected to a preferably equal amount of movement of the ejection devices 10, 13 away from the projectile bearing 2 and the propellant charge bearing 4. Furthermore, the coupling 14 causes a movement of the insertion devices 8, 9 of the projectile bearing 2 and the propellant charge bearing 4 away with a preferably equal amount of movement

Ejecting means 10, 13 is connected to the projectile bearing 2 and the propellant charge bearing 4 to. The coupling 14 does not necessarily have to be rigid. A rigid coupling 14 is merely the simplest embodiment of such a coupling. Rather, the coupling 14 may also have a more complex synchronized control operation for the plug-in devices 8, 9 and the ejection devices

10, 13 are realized, which is the insertion means 8, 9 and ejection devices 10, 13 impressed by the synchronization means 15. The Optionality of both the synchronization means 15 and the coupling 14 is expressed by the dashed representation of these components. Preferably, the synchronization means 15 is externally driven, which can be ensured in an advantageous manner that in each case a cycle started is completed and is terminated with the operation of the ejector 10 for the propellant charge bearing 5, 50, thus the timely output of a possibly still in the propellant charge chamber 5, 50 to ensure propellant charge 7.

In FIG. 5G, as in FIG. 4G, the firing pin device 77 is actuated in the firing position. In this case, the firing pin 777 strikes the propellant charge body 7 located in chamber 5. In contrast to the trouble-free operation of FIG. 4G, however, the propellant charge 7 does not explode in FIG. 5G due to a failure to ignite. Consequently, the projectile 6 remains in its chamber 3.

Figures 5H to 5J show the transition from the second position to the third position, the unloading position, as shown in Figures 5K and 5L. The transition from the second position to the third position takes place by rotation of the projectile bearing 2 and the propellant charge bearing 4 about the associated axis X or Y. In the unloading position, the ejection devices 13, 10 are now routinely activated. In this case, as shown in FIGS. 5K and 5L, the ejector pins 13, 10 enter the chambers 3, 5 filled with the ignition failures 6, 7 and push the projectile 6 remaining in the chamber 3 and the propellant charge 7 remaining in the chamber 5 preferably opposite to the insertion direction of the respective chambers 3, 5 out.

In a weapon system designed in accordance with FIGS. 4 and 5, it is advantageously ensured that each cycle which begins with the loading of a chamber 3, 30 of the projectile bearing 2 and a chamber 5, 50 of the propellant charge bearing 4 is always complete until unloading in particular the chamber 5, 50 of the

Propellant charge bearing 4 is traversed, regardless of when (especially in an automatic weapon) the trigger is released and also regardless of whether in particular the last charged propellant charge 7 is a failure or not. This can ensure that a propellant charge 7, which is introduced at a certain time in a chamber 5, 50 of the propellant charge bearing 4 (and thus in the combustion chamber), dwells in each case only for a very short period of time in the combustion chamber. Either the charged propellant 7 intentionally ignited a short time later in the firing position, or in case of failure of the propellant charge 7, or in case of interruption of the firing order, ejected from its propellant charge chamber 5, 50. As a result, inadvertent ignition of a propellant charge 7 even with heated propellant charge bearing 4 can be prevented in all conceivable cases with high probability. As a result, the safety of the conventional weapon system according to the preamble of claim 11 is significantly improved.

All of the features and advantages associated with the subject matter of claim 11 and the subject matter of claims 12 to

15 described are readily with the subject matter of the independent claim 1 and the subject matter of claim 1 dependent

Claims 2 to 10 combined. Such a combination is particularly favored by the identical wording of the preambles of the two independent claims 1 and 11. By such a combination, the advantages of both embodiments can be advantageously combined in a single weapon system.

Reference numerals and figures in the claims are for illustrative purposes only and are in no way to be construed as limiting the scope of protection as determined by the language of the claims.
