Definitions

  • the invention relates to a muzzle brake for a tube weapon with a tube piece aligned with the core tube and having bores and diametrically opposed gas outlet openings which are essentially perpendicular to the longitudinal axis of the tube.
  • Such a muzzle brake is known from military technology 6/1974, page 250.
  • the effect of a muzzle brake consists in reducing the proportion of the propellant gas escaping from the muzzle immediately after the projectile, as a result of which various advantages can be achieved.
  • the size of the effective return energy and the return of the pipe can be reduced, which can also increase the rate of fire, for example.
  • Gas outlet openings connected to the muzzle brake which are arranged diametrically opposite one another in a plane running parallel to the surface of the earth, can furthermore prevent gases escaping after the shot from hitting the earth's surface and whirling up dust clouds obstructing vision.
  • the flue gas distribution of the powder gases emerging from the mouth can be influenced with the muzzle brake.
  • the invention is based on the object of specifying a novel muzzle brake which is particularly suitable for large-caliber weapons and which is simple to manufacture and with which, in particular, sabot projectiles should also be able to be fired.
  • the new muzzle brake is also intended to improve the flue gas distribution in order to prevent the sighting means being adversely affected by flue gases.
  • Fig. 1 shows a partial sectional view of the side view of the muzzle brake 10, which comprises a pipe section 22 (Fig. 3), the inner diameter of which is of the same caliber.
  • Bores 14 are made in the tubular piece 22 and are arranged in several planes 15 running one behind the other and parallel and perpendicular to the longitudinal axis of the weapon barrel.
  • the bores 14 are evenly spaced on the circumference of the tube 22 in each plane 15 and preferably extend in the radial direction.
  • the design of the inner diameter of the pipe section 22 of the same caliber ensures that when sabot projectiles are fired, the sabot detachment can only be initiated after the projectile has emerged from the muzzle of the muzzle brake.
  • bores 14 ' are arranged at an angle o ( _) to the longitudinal axis of the pipe in conical surface areas one behind the other. If necessary, the effect of the muzzle brake can be increased by the oblique arrangement of the bores 14'.
  • the bores 14 and 14 ' are angularly offset from one another in adjacent planes 15 or in adjacent conical lateral surfaces in such a way that they lie "at a gap" to one another. This ensures that there is a uniform distribution on the inner surface of the muzzle brake 10 between the cross-sectional areas of the bores 14, 14 'and the inner tube surface.
  • the ratio of the area occupied by the holes to the total inner surface area should advantageously not be greater than about 0.5 . In this way, the life of the muzzle brake is increased because wear is very even.
  • the cross-sectional areas of the bores 14, 14 ′ are preferably circular; however, other cross-sectional shapes are possible, but they are more difficult to manufacture.
  • annular grooves 13 are formed in the outer circumferential surface 40 of the tube 24, into which the outlet openings of the bores 14 each lying in a plane 15 open.
  • the grooves 13 are arranged in evenly spaced planes which run parallel to one another and perpendicular to the longitudinal axis of the tube in such a way that they also form the Connect the outlet openings of the bores 14 'to one another.
  • the grooves 13 thus form channels running around the tube 24, which discharge the flue gases emerging from the interior through the bores 14 and 14 'very effectively.
  • a spiral groove can also be provided, which winds around the tube 24 of the muzzle brake 10 and connects all outlet openings of all bores 14, 14 'to one another.
  • the tube 24 of the muzzle brake 10 is coaxially surrounded by a jacket tube 12 which rests gas-tight on the webs present between the grooves 13 and which is diametrically opposed. overlying projections 21 with outlet openings 30 arranged there. In a manner known per se, these outlet openings are arranged in a plane lying parallel to the surface of the earth, in order to ensure that escaping gases can only escape laterally and not to Whirl up dust clouds that obstruct the view.
  • the muzzle brake is expediently designed to be screwed onto the weapon barrel. In this way it is easy to replace and can be exchanged for other muzzle brakes if necessary without having to replace the entire barrel.
  • a particularly good effect of the muzzle brake is achieved by the novel arrangement of bores 14, 14 'and circumferential grooves 13.
  • the smoke gases generated during the shot are effectively removed, with the result that an unavoidable visual obstruction by these smoke gases only lasts for a comparatively short period of time compared to conventional solutions.
  • This offers the particular advantage that when a projectile is fired, the path of the projectile and its target impact can be observed with optical means. Furthermore, it is possible to increase the cadence without the accuracy of the target suffering due to a lack of observation of the target due to smoke obstruction.
