Definitions

  • the technical field of the invention is that of brakes muzzle for weapons tubes, in particular of large caliber.
  • a muzzle brake generally has at least two transverse openings which make the interior of the brake communicate with at least two gas receiving vanes, vanes integral with the outside of the brake.
  • the propellants When firing a projectile, the propellants are guided by the gills towards the blades and they then exert a thrust on them which compensates for the recoil of the tube tear.
  • Patent US1363058 (basis for the preamble of claim 1) shows such a muzzle brake.
  • Muzzle brakes are commonly used in the field of field artillery, however their employment is reduced for artillery equipping tanks or vehicles due to the disruption they cause to shooting of arrow projectiles, or sub-calibrated projectiles at detachable shoe.
  • the muzzle brake according to the invention allows (any keeping an excellent yield) to avoid any initial disturbance of the projectile trajectory as well damage to the internal surfaces of the brake.
  • the subject of the invention is a muzzle brake for a weapon barrel, especially of large caliber, and comprising at minus two gills making the interior of the brake communicate with at least two gas receiving vanes which are integral with the outside of the brake, brake having at least a cylindrical internal bearing to the gauge of the tube and arranged downstream of the gills in the direction of travel of a projectile fired by the tube, brake characterized in that the cylindrical inner surface is separated from the opening (s) which precede it by a concave surface of revolution whose the concavity is oriented towards the rear of the brake.
  • the surface of revolution is a conical surface.
  • the surface of revolution extends longitudinally over a length which is between 1.5 and 4 times the length of the cylindrical seat.
  • the maximum diameter of the surface of revolution is preferably between 108% and 112% of the caliber D of the tube.
  • the brake comprises at least two stages, each consisting of at least two vents and at least two gas receiving vanes, two consecutive stages being separated by a cylindrical span preceded by a surface of revolution.
  • the muzzle brake 1 is here a brake which comprises a first stage la and a second stage 1b.
  • Each stage includes two openings 2a, 2b and two blades of reception of gases 3a, 3b.
  • vents 2a, 2b communicate the interior of the brake 1 with the vanes which are integral with the outside of the brake.
  • the brake is fixed by thread at the end of a tube 4 of a weapon, here a rifled tube whose caliber (or diameter to stripes background) is D.
  • the interior of the brake has two cylindrical seats 5a, 5b to the size of the tube.
  • a first litter 5a is arranged downstream of the first openings 2a in the direction of course of a projectile fired by the tube.
  • a second range 5b is located downstream of the second vents 2b and emerges outside the brake.
  • the internal surface of the brake is also generally the caliber D of the barrel, both at the gills and cylindrical bearings 5a, 5b.
  • each litter 5a or 5b is separated from the gills that precede it by a surface of conical revolution 6a or 6b whose concavity is oriented towards a rear part of the brake intended to be fixed to tear.
  • Each conical surface extends longitudinally over a length (La or Lb) which is between 60% and 80% of the length La + Pa or Lb + Pb of the dawn considered (Pa and Pb being the lengths of the cylindrical spans 5a and 5b).
  • the length La (or Lb) is understood between 1.5 and 4 times the length Pa (or Pb).
  • the maximum diameter ⁇ a or ⁇ b of the conical surface 6a, 6b is between 108% and 112% of the caliber D of the tube.
  • a maximum diameter ⁇ a or ⁇ b such that the belt of an arrow projectile cannot come completely out of its housing on the shoe of the projectile.
  • the aerodynamic forces exerted on the projectile as well as centrifugal force (due to scratches) have the effect of initiating an opening movement of the hoof of the projectile.
  • the gases are also exerted on the belt and have the effect of removing it from the hoof.
  • the projectile belt is therefore subjected to a extension effort and it initiates an outward movement from its hoof housing.
  • the internal diameter of the brake is of the caliber of the weapon at the level of the gills, the belt is deformed opposite of these.
  • the conical surfaces 6a and 6b therefore go in turn receive the projectile belt contact and they will guide it so as to reposition it in its hoof housing.
  • the cylindrical ranges 5a and 5b to the caliber of the weapon then ensure the guidance of the projectile which leaves the weapon without disturbance or obliquity.
  • each conical surface with a surface of concave revolution whose concavity will be oriented towards the rear of the brake.
