Definitions

  • the invention relates to a muzzle brake according to the features specified in the preamble of claim 1.
  • Such a muzzle brake can be seen as known from "Military Technology" 6/74, page 250, Figures 4 and 5.
  • gas outlet openings are known, the front impact surface and rear sliding surface of which are directed obliquely and parallel to the rear at an undetermined angle. There is no indication of the angular range of the impact surface in which a maximum reduction in the return energy of a weapon barrel can be achieved during the firing of a spin-stabilized projectile.
  • this muzzle brake does not contain a continuous inner bore, but rather extensions in the area of the outlet openings that go beyond the pipe inner diameter.
  • the existing gas pressure in the weapon barrel is quickly reduced in the area of the extensions, so that no further or possibly only a slight increase in the speed of the projectile can be achieved in the area of the muzzle brake.
  • FR-A-1597401 and US-A-4 545 285 disclose separate, e.g. H. muzzle brakes which can be screwed onto the gun barrel are known, the inside diameter of which corresponds exactly to the inside diameter of the gun barrel and thus the caliber diameter of the ammunition. From document US-A 4 545 285 it can also be seen that there are difficulties for gun barrels with a towing profile to separate the muzzle brake. FIGS. 7 to 9 therefore only show muzzle brakes with a tension profile that are connected in one piece to the weapon barrel. In the case of the problem of connecting a separate muzzle brake to a weapon barrel provided with trains, particular difficulties have to be overcome, the solution of which is also not disclosed from the aforementioned prior art.
  • the trains located in the area of the muzzle brake generate a comparatively high torque when passing through the storey on a separate muzzle brake, which can cause the material to set in the connecting elements to the weapon barrel and, as a result, leakage in the transition area of the weapon ear to the muzzle brake.
  • the muzzle brake described at the beginning requires an additional stable securing when used on a large-caliber weapon barrel.
  • a muzzle brake shown in DE-32 03 807 A1 it can be secured against twisting in the region of a threaded part enveloping the weapon barrel by a spring engaging in the weapon barrel, previously braced and locked by a lock nut shown in FIG. 1 of the present invention the spring must be secured against radial detachment.
  • powder gases and moisture can, for example, impair the service life of an elastomer seal used, which can result in consequential damage due to corrosion in the attachment area of the muzzle brake.
  • a muzzle brake which is formed from disks stacked one above the other and is screwed together like a flange using long stud bolts.
  • the rear end of the bolt serves the purpose of fastening the muzzle brake to the weapon barrel via wedge-shaped shells.
  • many individual parts are required, the setting behavior of which does not rule out leaks due to their overall screwing on the muzzle brake stop surface at the front end of the barrel.
  • a muzzle brake for a handgun is known to be known, but which already has bores as gas outlet openings in the part of the front weapon barrel overlapping the muzzle brake and contains further gas outlet openings in front of the weapon tube which are larger than that Are inside diameter of the barrel.
  • the gas outlet openings extending in length beyond the inside diameter of the weapon barrel cause a rapid gas pressure drop within the muzzle brake and thus a lower initial velocity of the projectile, but at the same time an increase in the blast pressure and an increase in the side firing flash.
  • the muzzle brake according to the invention preferably achieves significant advantages when used on large-caliber barrel weapons, for example on gun barrels of field or armored howitzers.
  • the axial inner bore of the muzzle brake has an inner diameter corresponding to the draw diameter of the weapon barrel and its rear end ends at the surface of the radially extending stop, little gases can flow past the projectile during the projectile passage, whereby the gas pressure reduction within the muzzle brake remains comparatively low and one Increase in the initial velocity of the projectile, for example by 20 m / sec.
  • the lateral gas outlet openings have a different opening length, starting from the train diameter in the rear area of the muzzle brake, which increases significantly in the front direction, while the gas outlet openings in the front area of the muzzle brake have the same opening length.
  • the comparatively short opening length produces a reduction in the impact pressure and the muzzle flash in the first rear passage phase of the projectile, while in the second front passage phase of the projectile the gases flow against the baffles in full slot length, whereby the return energy of the barrel with a high efficiency of, for example, 50 % is braked.
  • the high efficiency is achieved, for example, when the angle of the impact surface is arranged in an angular range from 100 to 105 ° to the inner bore and the angle of the gas guide surface in an angular range from 110 to 120 ° to the inner bore.
  • the muzzle brake according to the invention is connected at its rear end encasing the weapon barrel to the weapon barrel via a separate tensioning device and can be preloaded in a defined manner, the tensioning device exerting a high tensile force on the rear end of the muzzle brake, so that the stop surface is pressed tightly against the end face of the weapon barrel muzzle end.
  • the sealing abutment of the muzzle brake stop on the front of the gun barrel prevents penetration the powder gases escaping from the gun barrel and moisture, which prevents damage from corrosion in the fastening area.
  • the muzzle brake is therefore also easy to disassemble and assemble.
  • the clamping device consists of a flange connected to the barrel, which allows the use of small-sized, high-strength screws that are self-locking and can be preloaded and thus easily apply high surface pressure and thus the desired sealing effect between the stop surface of the muzzle brake and the front of the barrel achieve.
  • FIG. 1 illustrates the front end of a large-caliber weapon barrel 12 which, for example, has a caliber diameter d2 of 155 mm and on the outside receives a muzzle brake 10.1 in a manner known per se.
  • the muzzle brake 10.1 can be placed coaxially to the barrel core axis 16 at the muzzle end of the gun barrel 12 up to a radially extending annular stop 20 and contains an internal thread 42 which can be screwed onto a corresponding external thread of the gun barrel 12 for fastening the muzzle brake 10.1.
  • a spring 44 engaging in a groove 46 of the weapon barrel 12 secures the muzzle brake 12.1 against rotation.
  • the muzzle brake 10.1 is given a defined position by a lock nut 62.
  • the lock nut 62 is connected behind the muzzle brake 10.1 via a thread to the weapon barrel 12 and, when countered, shifts the muzzle brake 10.1 in the front direction 53, whereby, however, the stop 20 of the muzzle brake 10.1 is released by a gap 66 from the end face 36 of the weapon barrel 12 .
  • the seal 64 which consists, for example, of an elastomer, can be destroyed by hot powder gases and powder residues and, in addition, corrosion damage caused by water and moisture on the centering bore 19 of the muzzle brake and on the centering jacket 21 of the weapon barrel 12 and, if appropriate, can occur on the mounting thread 42.
  • the lock nut 62 had to be additionally secured against twisting and the spring 44 against radial removal by means of a securing element 58 which can be screwed onto the muzzle brake 10.1 by means of screws 60.
  • FIGS. 2 to 5 illustrate the design and attachment of the muzzle brake 10 according to the invention at the front end of the weapon barrel 12.
  • the muzzle brake 10 is connected to the weapon barrel 12 at its rear end enveloping the weapon barrel 12 via a separate tensioning device 22 and can be preloaded in a defined manner.
  • the tensioning device 22 exerts a high tensile force on the rear end of the muzzle brake 10, so that the stop surface 20 of the muzzle brake 10 is pressed tightly against the end face 38 of the weapon barrel muzzle end.
  • the clamping device consists of a flange 28 connected to the weapon barrel 12, which contains axially extending bores 32 for receiving screws 30, while the muzzle brake 10 has threaded bores 34 on the end face in a cylindrical extension 50 for fastening the screws 30.
  • the screws 30 of the clamping device 22 consist of a high-strength material, preferably steel, with a minimum tensile strength of 1200 N / mm2.
  • the flange 28 is supported in a space-saving manner via a fine thread 36 with respect to the weapon barrel 12.
  • the high-strength screws 30 can be heavily loaded despite their space-saving dimensioning and therefore have a self-locking effect due to their high pretensioning force, so that additional screw locking elements can be omitted.
  • the high, in the rearward direction 52, tensile force of the screws 30 is transmitted from the stop surface 20 of the muzzle brake 10 to the front end surface 38 of the weapon barrel 12, whereby a specific surface pressure of, for example, 200 N / mm2 with good between the stop surface 20 and the end surface 38 Sealing effect, in particular also against a gas pressure of 800 bar existing during the shooting operation.
  • the centering 19, 21 and the thread 42 are thereby protected against corrosion damage, the use of the known sealing ring 64 being unnecessary.
  • the muzzle brake 10 can be secured against rotation by a spring 44 with the screw connection 48 as before.
  • the tensioning device according to the invention enables the thread 42 and the spring 44 with the groove 46 to be eliminated even due to the high pretension.
  • Figures 3 to 5 show the gas outlet openings 14 arranged in the lateral length region of the muzzle brake 10 transversely to the tube core axis 16, the rear gas outlet opening 14 having a minimum opening length l 1.
  • the axial inner bore 18 of the muzzle brake 10 has a pull diameter d 1 and not the caliber diameter d 2 of the weapon barrel 12 corresponding inner diameter d, its rear end ending on the surface of the radially extending stop 20.
  • the gas outlet openings 14 have baffle and sliding surfaces 24, 26 which have a different opening length 1 in the rear area of the muzzle brake 10 and an identical opening length 1 in the front area, each with a constant opening width b.
