Definitions

  • the present invention relates to a chamber muzzle brake [KMB].
  • KMB chamber muzzle brake
  • Corresponding muzzle brakes are used for mounting on gun barrels in order to reduce recoil loads acting on the gun barrel after a shot.
  • the muzzle brake can also reduce the recoil load indirectly via the barrel to the vehicle or to the weapon station.
  • the shape and size of a corresponding chamber muzzle brake is essentially dependent on the required performance figure.
  • KMB with at least one chamber and laterally oriented outflow openings are known.
  • the associated outflow openings are often arranged symmetrically to the sides.
  • a sub-caliber projectile is a projectile with a sabot [TK].
  • TK sabot
  • the sabot at least partially surrounds the projectile and balances the caliber of the weapon barrel. By burning off the powder contained in the propellant, the projectile is propelled with the help of the TC.
  • Hole muzzle brakes are also known from the prior art.
  • a cylindrical body provided with several holes is included here, which deflects the gases produced during the shot to the side.
  • chamber muzzle brakes consist of a continuous chamber in a cylindrical base body, this chamber having radially arranged outflow openings. The radially arranged outflow openings cause the outflowing powder gases to be diverted to the side. If a projectile with a sabot passes through such a muzzle brake, the escaping powder gases are discharged radially through the outflow openings, which causes the aforementioned reduction in the recoil load.
  • a corresponding chamber muzzle brake is known, for example, from US 2005/0252365 A1.
  • Two radially arranged outflow openings are provided through which the escaping powder gases are diverted laterally from the muzzle brake when firing.
  • the muzzle brake itself is placed on the end of a weapon barrel.
  • An aforementioned hole muzzle brake is known, for example, from EP 0 085 754 A1.
  • This muzzle brake is also arranged at one end of the weapon barrel and has a cylindrical body which has a large number of radially arranged small bores.
  • Modern sabot usually consist of three segments, which means that in a chamber muzzle brake with two outflow openings, a different transverse force load acts on each of the three cage segments due to the powder gases flowing out to the side. As a result, the sabot could possibly not separate symmetrically from the projectile and negatively affect the precision of the projectile.
  • the object of the present invention is therefore to disclose a muzzle brake in which the same transverse force load occurs when the barrel passes through, in particular when the muzzle brake passes through, each sabot segment when using a three-part sabot and thus the sabot can be detached from the projectile as symmetrically as possible.
  • Another object of the present invention is to achieve a high performance figure.
  • a weapon system consisting of a weapon barrel, a projectile and the aforementioned muzzle brake.
  • a chamber muzzle brake is proposed for ammunition with a three-part sabot.
  • Three-part sabot have become established for projectiles because they have good impact behavior.
  • the proposed chamber muzzle brake consists of a hollow body, which has outflow openings arranged radially on the body.
  • the chamber muzzle brake according to the invention thus has three outflow openings each with the same spacing and each at the same angle to one another.
  • an outflow opening can be assigned to each segment of the sabot, so that in the case of a projectile with the sabot, the same transverse force can act on a segment of the sabot when it is fired.
  • the chamber muzzle brake itself preferably has a fastening means in order to fasten the chamber muzzle brake to the weapon barrel.
  • a screw connection is conceivable, for example, whereby the chamber muzzle brake can be screwed onto a corresponding external thread of the weapon barrel by means of an internal thread.
  • the chamber muzzle brake is preferably arranged on the weapon barrel in such a way that one of the outflow openings points away from the floor on which the weapon system with the weapon barrel stands. Accordingly, the other two outflow openings point away as diagonally as possible to the sides.
  • the aim of this arrangement is to stir up soil contamination as little as possible when it is fired. Whirled up soil pollution poses a risk of injury, but in any case the view is impaired. It is important to prevent both of these as much as possible.
  • the chamber muzzle brake according to the invention has a central axis which is aligned with the central axis of the weapon barrel when the chamber muzzle brake is mounted on a weapon barrel.
  • the chamber muzzle brake In order to reduce the weight of such a muzzle brake, it is proposed to at least partially cut out the material of the chamber muzzle brake. For this purpose, it is proposed to provide the chamber muzzle brake in a special embodiment with at least one recess in order to reduce the weight. These recesses can be designed according to performance specifications and must be designed in such a way that the chamber muzzle brake can absorb the corresponding forces acting on it, but is nevertheless not designed to be too heavy.
  • the chamber muzzle brake be made of metal. It is particularly preferably proposed that the chamber muzzle brake be designed in one piece. In this way, a simple manufacturing process for a muzzle brake according to the invention can be designed become.
  • a system is also claimed, consisting of a weapon barrel, which is assigned to a mobile or stationary weapon station.
  • mobile weapon stations can be vehicles, with manned and unmanned vehicles also being possible.
  • Stationary weapon stations can also have such a weapon barrel.
  • the system comprises the aforementioned chamber muzzle brake, a projectile with a sabot, which is arranged in the weapon barrel.
  • the chamber muzzle brake is arranged at one end of the weapon barrel.
  • the ammunition is equipped with a three-part sabot.
  • the three parts of the sabot are particularly preferably arranged symmetrically in order to allow equal forces to act on the corresponding outflow openings.
  • Figure 1 A chamber muzzle brake according to the invention in perspective
  • Figure 2 A chamber muzzle brake according to the invention with an inserted projectile
  • FIG. 1 shows a chamber muzzle brake 1 with a hollow body which is essentially cylindrical.
  • three outflow openings 2 are also provided and these are arranged radially on the body of the chamber muzzle brake 1.
  • the three outflow openings 2 are arranged radially on the body of the chamber muzzle brake 1 in such a way that they have an angle 7 of 120 ° to one another.
  • the chamber muzzle brake 1 is intended to be arranged on a weapon barrel 3, the chamber muzzle brake 1 comprising at least one fastening means 6 for this purpose.
  • the fastening means 6 is designed as a screw connection, for example.
  • the chamber muzzle brake 1 has a thread.
  • the chamber muzzle brake 1 can be screwed onto the weapon barrel 3 via this.
  • the chamber muzzle brake 1 as well as the weapon barrel 3 each have a central axis 4, the two central axes 4 being aligned with one another when the muzzle brake 1 is mounted on the weapon barrel 3.
  • recesses 5 can be provided. The weight of the chamber muzzle brake 1 will then be reduced by the material removed.
  • FIG. 2 shows the introduction of a corresponding projectile 8 into a weapon barrel 3, FIG. 2 showing the chamber muzzle brake 1 according to the invention in a front view.
  • the projectile 8 used comprises a three-part sabot. Alignment of the TC to the openings of the KMB, as can be seen in FIG. 2, is not absolutely necessary. Depending on the ammunition, certain orientations can result in advantages in terms of impact behavior.
  • the recesses 5 in order to reduce the weight of the chamber muzzle brake 1 can again be seen clearly. Since the three segments of the sabot are arranged symmetrically, the outflow openings 2 of the chamber muzzle brake 1 are each arranged at the same distance, namely 120 ° from one another. This angle 7 (120 °) therefore exists between two outflow openings 2 in each case.
  • the invention is not restricted to the aforementioned features. Rather, further configurations are possible.
  • further fastening means 6 would be conceivable, for example snap-in connections or non-detachable connections such as welding.
