- the tubular element and the body of the brake mouth can be made in one piece from a molding outline for example.
- the barrel and the tubular element do not form only one piece.
- a first advantage of the following muzzle brake the invention lies in its energy efficiency important and therefore in the possibility offered to the system weapon to fire high energy ammunition.
- Another advantage of this muzzle brake is ability to fire an under-calibrated projectile without interfere with each other.
- Another advantage of the invention lies in the offering a low mass muzzle brake facilitating the pointing of the weapon.
- FIG. 1 represents an embodiment of the invention of a muzzle brake, known as a single stage, is to say having only one row of blades and commonly called “tulip” muzzle brake.
- This brake mouth 20 consists of a cylindrical part 21 linked to barrel tube 30 by a threaded connection 8 braked by a lock nut system 9 and oriented in a known manner by a key (not shown) relative to the barrel 30 and a body 22 provided with blades 22b on which come rely on propellant gases to generate a force of opposite direction to that generated by the firing of the ammunition, 22nd gills to relax these propellant gases and eject them outwards and from an outlet projectile 22f.
- the internal part of the body is composed of divergent frustoconical part 22a followed by a part converging 22b forming the blades and a surface 22c substantially perpendicular to the axis YY 'of the barrel, the divergent part 22a and convergent part 22b are connected by a curved surface 22d.
- the outer surface 22h of the body 22 is substantially parallel to the surfaces internal of said body.
- a 22g reinforcement forming a beam is placed at the front of said body.
- the internal shape of the muzzle brake 20 allows it to have a high energy efficiency, of the order of 50 at 60%, this being the ratio of the recoil energy of the barrel with and without muzzle brake.
- the jacket 5 is centered relative to the barrel 30 and to the muzzle brake 20 via the ranges 6a, 6b of the jacket 5 cooperating with the bearing surfaces 7a, 7b practiced in the internal wall of the body 22 and by through the scope 6d of the cooperating shirt 5 with the range 7d practiced in the barrel 30.
- the jacket 5 is also positioned axially without clearance between the muzzle brake 20 and the barrel 30 by the bias of the 6th face of the shirt 5 cooperating with the front edge 31 of the barrel on the one hand, and through the face 6c of the jacket 5 cooperating with the face 7c of the body 22 and shims 11 whose value is determined on the other hand.
- the jacket 5 is immobilized in rotation by muzzle brake 20 via a key 25 engaged in a groove 27 of said brake mouth and cooperating with a groove 51 made in the shirt 5.
- This key 25 is linked to the muzzle brake 20 by means of a screw 26 cooperating with said key and a tapping 28 made in the brake mouth 20.
- a chamfer 29 produced on the internal face of the jacket 5 on the side in contact with the barrel 30 facilitates the passage of the shoe of the ammunition in said shirt.
- the jacket 5 has an average thickness of 5 to 10 mm and is made of a material having a limit elastic of about 1000 MPa.
- the jacket 5 is pierced with vents 54, which open into the internal volume of the body 22, in the form cylindrical whose angle ⁇ 1 with respect to the axis YY 'of barrel 30 is substantially equal to the angle ⁇ 2 of the wall 22a of the body 22 relative to said axis YY '.
- the diameter vents 54 is between 10 and 20 mm.
- the number vents 54 should be as large as possible to let most of the propellant gases pass, but ensuring that the distance d4 between said is sufficient to withstand pressure from propellant gases.
- the shoes of the sub-calibrated projectile remain linked to the core during their passage through the muzzle brake 20 thanks to the jacket 5 which is of the same diameter d2 or d3 as the barrel 30.
- the shoes freely detach from the core at the outlet of the muzzle brake 20, thus producing no parasitic effect on the core or damage to the muzzle brake 20.
- the propellant gases are directed by the vents 54 towards the blades 22b to generate a force. of opposite direction to that induced by the shooting.
- FIG. 2 shows a muzzle brake according to the invention identical to the embodiment shown in Figure 1, but the jacket 5 is not smooth and has stripes 40 identical to those of barrel 30 and the extending. In this case, it is necessary to orient said shirt so that the continuity of the stripes of the barrel 30 and liner 5 is ensured.
- a key 25 carried by the muzzle brake 20 cooperates with a groove 51 practiced for part 51a in canon 30 precisely positioned with respect to scratches of said barrel and for the other part 51b in the folder 5 precisely positioned in relation to the scratches of said shirt.
- This key 25 is linked to the brake mouth 20 by means of a screw 26 cooperating with said key and a tapping 28 practiced in the muzzle brake 20.
- This configuration makes it possible to maintain the rotation of the projectile during its passage in the brake mouth 20 which gives it a better stabilization on trajectory.
- FIG. 3 illustrates an alternative embodiment vents 54.
- These have an internal profile opening into the internal volume of the body 22, in the form ovoid whose major axis is parallel to the axis of the barrel YY 'and inclined at an angle ⁇ 3 relative to the axis of the barrel YY 'substantially equal to the angle ⁇ 2 of the internal wall 22a of the body 22 relative to said axis YY '.
- the major axis is between 15 and 40 mm and the small axis is between 10 and 15 mm.
- the number of vents 54 should be as large as possible to let pass most of the propellants but in ensuring that the minimum distance d4 between said is sufficient to withstand pressure from propellant gases.
- Figure 4 illustrates another variant of realization of the vents 54. These are ovoid in shape and their major axis is perpendicular to the axis of the barrel YY 'and inclined at an angle ⁇ 3 with respect to the YY' axis of the barrel substantially equal to the angle ⁇ 2 of the internal wall 22a of the body 22 relative to said axis YY '.
- the major axis is between 15 and 40 mm and the minor axis is between 10 and 15 mm.
- vents 54 must be the largest possible to let most of the propellants but making sure that the distance minimum d4 between said vents is sufficient to withstand the pressure of propellant gases.
- Figure 5 illustrates another variant of realization of the vents 54 having a profile cylindrical 54a of diameter substantially between 10 and 20 mm opening on the internal side of the jacket 5 followed of a frustoconical profile 54b opening on the external side of said jacket in the internal volume of the body 22.
- the angle of inclination ⁇ 4 relative to the axis YY 'of the barrel 30 of the frustoconical part 54b is substantially equal to the inclination ⁇ 2 of the internal wall 22a of the body 22 by report to said axis YY '.
- the number of vents 54 must be as large as possible to let the largest part of the propellants, but making sure that the distance d4 between said vents is sufficient to withstand the pressure of propellant gases.
- This alternative embodiment of the vents 54 has the advantage of being more easily manufactured industrially.
- Figure 6 shows an alternative embodiment the muzzle brake according to the invention in which the muzzle brake 20 and the tubular element 5 do not form more than one piece that can come from a rough molding for example.
- This achievement turns out particularly economical, because it does not require the positioning of a jacket 5 relative to the brake mouth 20 and relative to the barrel 30.
- Figure 7 shows a variant of the brake mouth according to the invention in which the element tubular 5 is part of the same part as the barrel 30.
- the muzzle brake is oriented relative to the barrel 30 in a known manner by a key not shown, but of the type of that described in relation to Figure 1.
- the axial clearance between the tubular element 5 and the brake mouth 20 is canceled through the face 6c of the tubular element 5 cooperating with the face 7c of the body 22 and with adjustment shims 11 whose value is determined during assembly.
