Definitions
- the present invention relates to a modular muzzle brake assembly for an artillery weapon or cannon.
- the present invention also relates to a kit of parts for a modular muzzle brake assembly.
- Muzzle brakes are used to reduce the effects of recoil when a tubed weapon is fired.
- Muzzle brakes are configured to divert a portion of the propellant combustion gas venting from the barrel after a projectile has exited to reduce the recoil force on the barrel, and hence reduce stress on a support structure to which the barrel is attached. By diverting the gas, the forward momentum of the gas is reduced and the rearward momentum of the barrel is reduced by a corresponding amount. The greater the volume of gas and the greater the angle of diversion, the greater the recoil efficiency of the muzzle brake.

- kit of parts for a modular muzzle brake assembly for an artillery weapon or cannon comprising a plurality of modules configured to be releasably coupled together to define a passage for a projectile such that, when the artillery weapon or cannon is fired, propellant gas urges the projectile to pass through the passage, and wherein the plurality of modules include a plurality of baffles configured to divert at least a portion of the propellant gas in the passage.
- FIG. 1 to 10 an embodiment of a modular muzzle brake assembly 10 for an artillery weapon or cannon is shown.
- the description of the embodiment of Figures 1 to 10 will hereinafter refer to an artillery weapon 1, but the disclosure is also applicable to a tank gun or other cannon..
- the artillery weapon 1 has a gun barrel 3 that is pivotally mounted to a support structure 2.
- the muzzle brake assembly 10 is configured to be mounted to an end of the gun barrel 3 to divert a portion of the propellant combustion gas venting from the barrel 3 after a projectile has exited the barrel 3. Therefore, the muzzle brake assembly 10 reduces the recoil of the barrel 3 when the projectile is fired, and reduces stress on the support structure 2 to which the barrel 3 is mounted.
- the modular muzzle brake assembly 10 comprises a plurality of modules 20, 30, 50 configured to be releasably coupled together to define a passage 11 for a projectile (not shown) such that, when the artillery weapon 1 is fired, propellant gas urges the projectile to pass through the passage 11.
- the modules 20, 30, 50 may include baffles 30.
- the baffles 30 may define one or more gas diverting surfaces/regions for diverting the propellant gas such that recoil is reduced.
- the modularity of the muzzle brake assembly 10 means that individual modules, or groups of modules, can be swapped out of or rearranged in the muzzle brake assembly 10. This is advantageous because it has been found that baffles 30 within the muzzle brake assembly 10 will tend to wear at different rates. For example, baffles 30 located nearest to the end of the gun barrel 3 will tend to wear the quickest, coming into contact with the greatest amount of high velocity propellant combustion gas that is venting from the gun barrel 3, whereas baffles 30 located further away from the end of the gun barrel 3 will generally wear at a slower rate, because a proportion of the propellant gas will already have been diverted by baffles 30 closer to the gun barrel 3 and thus will not come into contact with the further away baffles 30. The temperature of the propellant gas will also decrease as the propellant gas travels away from the end of the gun barrel 3.
- the modular muzzle brake assembly 10 therefore allows for the modules subjected to higher wear to be replaced and/or maintained, whilst retaining the lower wear modules within the muzzle brake assembly 10 that do not yet need to be replaced and/or maintained. This is advantageous because it is easier to store and transport replacement modules rather than entire muzzle brake assemblies. Also, repair of the modular muzzle brake assembly 10 by replacing the worn modules is less expensive and more environmentally friendly than replacing the entire muzzle brake assembly 10. Furthermore, the order of the modules within the muzzle brake assembly 10 may be changed to achieve a more even wear of the modules.
- the modularity of the muzzle brake assembly 10 also allows for the performance of the muzzle brake assembly 10 to be adjusted or tuned. This is advantageous because it means that the efficiency of the muzzle brake assembly 10 can be adjusted, for example, based on one or more of: the type of projectile that is to be fired; environmental conditions; and/or, whether the artillery weapon 1 is being used under training conditions or in conflict.
- one or more of the baffles 30 may be swapped for baffle(s) 30 that are configured to divert the propellant gas in a more efficient or less efficient manner.
- the efficiency of the modular muzzle brake assembly 10 can be adjusted by adjusting one or more of: the number of baffles 30 in the assembly 10; the spacing between adjacent baffles 30; the orientation of one or more of the baffles 30; and/or, the order of the baffles 30 within the muzzle brake assembly 10.
- the muzzle brake assembly 10 comprises a mounting portion 20 that is configured to be mounted to the end of the barrel 3 of the artillery weapon 1.
- the plurality of modules includes the mounting portion 20.
- the mounting portion 20 may be a mounting member 20.
- the mounting portion 20 may be configured to be releasably mounted to the barrel 3, for example, being screwed on to the barrel 3 or bolted to the barrel 3.
- the mounting portion 20 is permanently fixed to the barrel 3, for example, being welded to the barrel 3 or integrally formed with the barrel 3.
- the mounting portion 20 is provided with a screw thread that engages a screw thread on the gun barrel 3.
- the mounting portion 20 forms part of the passage 11 and the propellant gas venting from the gun barrel 3 passes through the mounting portion 20 and contacts the interior of the mounting portion 20.
- the mounting portion 20 may be received on the outer circumferential surface of the gun barrel 3. Therefore, the propellant gas may substantially not come into contact with the interior of the mounting portion 20.
- the plurality of modules include a plurality of baffles 30 configured to divert at least a portion of the propellant gas in the passage 11.
- a gap 31 is provided between at least two baffles 30 of the assembly 10.
- the gap 31 forms a channel 31 such that at least a portion of the propellant gas in the passage 11 can pass through the gap 31 and thus is diverted to reduce the rearward momentum of the barrel 3 when the projectile is fired.
- the baffles 30 may comprise a channel within the baffle 30 itself.
- the channel may extend radially through a wall of the baffle 30 from the passage 11 to the exterior of the baffle 30 to provide a path for a portion of the propellant gas to follow such that the gas is diverted to reduce the rearward momentum of the barrel 3 when a projectile is fired.
- no gap is provided between adjacent baffles 30.
- the adjacent baffles 30 may abut each other.
- the modules of the modular muzzle brake assembly 10 include a plurality of spacers 50.
- Each spacer 50 is configured to space apart adjacent baffles 30 of the assembly 10 to form the gap 31 between the adjacent baffles 30.
- gaps are provided between adjacent baffles 30 without the use of spacers and, for example, the baffles 30 may instead be shaped to form said gaps.
- At least one of the baffles 30 comprises a first baffle member 32 and a second baffle member 33.
- the first and second baffle members 32, 33 are first and second baffle plates 32, 33.
- the first and second baffle members 32, 33 may be generally annular.
- each baffle 30 comprises a central channel 30B that forms a portion of the passage 11.
- the channels 30B are aligned to form at least a portion of the length of the passage 11.
- each baffle 30 is generally frustoconical in shape.
- shape of the or each baffle 30 may be selected to achieve particular flow conditions (e.g. pressure, velocity or direction of flow) of the propellant gas being diverted by the baffles 30.
- the baffles 30 may all have the same shape or different baffles 30 within the assembly 10 may have different shapes.
- the baffles 30 are each formed from a single component.
- the first and second baffle members 32, 33 are configured to be coupled together to form a respective baffle 30.
- the or each baffle 30 may have a hollow structure to allow for a weight saving in comparison to solid baffles 30.
- a space 34 is disposed between the first and second baffle members 32, 33 when the first and second baffle members 32, 33 are coupled together.
- One or each of the first and second baffle members 32, 33 has one or more depressions or grooves 32B, 33B that form at least part of the space 34 of the baffle 30.
- the first baffle member 32 has a plurality of grooves 32B and the second baffle member 33 has a plurality of grooves 33B.
- the grooves 32B, 33B of adjacent first and second baffle members 32, 33 together form a space 34 of the baffle 30. Manufacturing the baffles 30 from first and second members 32, 33 makes it easier to provide the space 34 within each baffle 30.
- the first baffle member 32 comprises a first flow control surface 35 and the second baffle member 33 comprises a second flow control surface 36.
- Propellant gas flowing out of the passage 11 via the gap 31 between baffles 30 impinges on the flow control surfaces 35, 36 and is directed in such a manner to retard the recoil of the barrel 3.
- at least a portion of the propellant gas may be diverted in a direction away from the fired projectile in order to oppose the rearward recoil motion of the barrel 3 when the projectile is fired.
- the first and second flow control surfaces 35, 36 converge (e.g. in a direction away from the passage 11) such that the cross-sectional area of the gap 31 reduces, thereby reducing the velocity and increasing the temperature of propellant gas entering the gap 31 from the passage 11.
- the first and second flow control surfaces 35, 36 may then diverge (e.g. in a direction away from the passage 11) such that the cross-sectional area of the gap 31 increases, thereby increasing the velocity of the propellant gas as it exits the gap 31.
- This increase in the velocity of the propellant gas as it exits the gap 31 will increase the rearward momentum of the propellant gas and therefore increase the braking force of the muzzle brake assembly 10 to mitigate recoil.
- the muzzle brake assembly 10 further comprises at least one coupling member 40 to couple the modules together.
- at least one, or a plurality, of the modules are releasable from the at least one coupling member 40.
- each coupling member 40 comprises an elongate member 40 that extends in a direction substantially parallel to the central axis A-A of the passage 11 of the muzzle brake assembly 10.
- the spacers 50 may each comprise a tubular spacer 50 that is configured to receive a portion of a coupling member 40.
- the spacers 50 may be configured to space apart a first baffling member 32 (e.g. of a first one of the baffles 30) from a second baffling member 33 (e.g. of a second one of the baffles 30) to form the gap 31 therebetween.
- each coupling member 40 may have an alternative form, for example, one or more bolts or other fasteners that are configured to couple adjacent modules together.
- each module has a screw thread or bayonet connection that is configured to couple to a screw thread or bayonet connection of an adjacent module.

- each receiving member 32A, 33A is an aperture through the respective baffle member 32, 33. It should be recognised that in some embodiments (not shown), one or more of the receiving members 32A, 33A may be a slot in the respective baffle member 32, 33. In some embodiments (not shown), one or more of the receiving members 32A, 33A may be a cut-out that extends into the radially inner or outer edge or surface of the respective baffle member 32, 33
- the muzzle brake assembly 10 comprise three coupling members 40.

That is, each first baffle member 32 comprises three receiving portions 32A and each second baffle member 33 comprises three receiving portions 33A that are each aligned with a respective receiving portion 32A of an adjacent first baffle member 32.
- Each coupling member 40 has first and second ends 41, 42.
- a first end 41 of the coupling member 40 is configured to be attached to the mounting portion 20.
- the first end 41 of each coupling member 40 comprises a thread (not shown) that is configured to be coupled to a threaded receiving portion 20A of the mounting portion 20.

- Each coupling member 40 comprises a stop 43.
- each stop 43 is provided at the second end 42 of the coupling member 40.
- Each stop 43 is configured to retain the modules on the respective coupling member 40. That is, the stop 43 has a larger size than the receiving portions 32A, 33A of the baffle members 32, 33 such that the baffle members 32, 33 are prevented from passing the stops 43 of the coupling members 40.
- each stop 43 is a flanged end of the coupling member 40.
- the or each stop 43 may have a different form, for example, comprising a bolt that engages a thread at the second end 42 of each coupling member 40.
- each coupling member 40 is attached to a common stop, which may be annular.
- the coupling members 40 may be releasably attached to the common stop.
- the coupling members 40 may be permanently attached to the common stop, in which case the coupling members 40 may be releasably coupled to the mounting portion 20 to allow for decoupling of the modules from the coupling members 40.
- the modular muzzle brake assembly 10 may be supplied pre-assembled or may be supplied as a kit of parts configured to be assembled to form the modular muzzle brake assembly 10.
- the kit of parts may optionally comprise additional modules (for example, baffles 30 and/or spacers 50) that can be substituted when modules of the assembly wear.
- the kit of parts may optionally comprise different types of baffles 30 that allow for adjustment of the muzzle brake efficiency, as described in more detail below.
- a second baffle member 33 is slid on to the three coupling members 40 until said second baffle member 33 contacts the respective stops 43 of the coupling members 40.
- a spacer 50 is slid on to each of the coupling members 40, and then a first baffle member 32 and an additional second baffle member 33 are slid on to the coupling members 40 (in that order) until each spacer 50 contacts the second baffle member 33 already coupled to the coupling members 40, the first baffle member 32 contacts the spacers 50, and the additional second baffle member 33 contacts the first baffle member 32 such that the first baffle member 32 and additional second baffle member 33 together form a baffle 30.
- each stop 43 is configured to be engaged by a socket or wrench and, for example, may have a hexagonal shape.
- the coupling members 40 are first attached to the mounting portion 20, the modules are then slid on to the coupling members 40, and then the stops 43 are attached to the coupling members 40 to retain the modules in position on the coupling members 40.
- the modularity of the muzzle brake assembly 10 means that individual modules, or groups of modules, can be swapped out of the muzzle brake assembly 10. This is advantageous because it is easier to store and transport replacement modules rather than entire muzzle brake assemblies. Also, repair of the muzzle brake assembly 10 by replacing the worn modules is less expensive and more environmentally friendly than replacing the entire muzzle brake assembly 10.
- the order of the modules within the muzzle brake assembly 10 may be changed to achieve a more even wear of the modules. For example, a module in a higher wear position (e.g. closer to the gun barrel 3) can be swapped for a module in a lower wear positon (e.g. further away from the gun barrel 3).
- the modularity of the muzzle brake assembly 10 allows for the performance of the muzzle brake assembly 10 to be adjusted or tuned.
- the efficiency of the muzzle brake assembly 10 may be adjusted.
- one or more of the baffles 30 may be replaced with baffle(s) that are configured to divert the propellant gas in a more efficient manner, for example, diverting a greater volume of propellant gas and/or at a greater angle of diversion to increase the recoil efficiency of the muzzle brake assembly 10.
- the efficiency of the muzzle brake assembly 10 can be adjusted, for example, based on one or more of: the type of projectile that is to be fired; environmental conditions; and/or, whether the artillery weapon 1 is being used under training conditions or in conflict.
- the efficiency of the modular muzzle brake assembly 10 can be adjusted by adjusting the number of baffles 30 in the muzzle brake assembly 10. Increasing the number of baffles 30 will increase the efficiency of the muzzle brake assembly 10, whereas reducing the number of baffles 30 reduces the efficiency but makes the muzzle brake assembly 10 more lightweight. The length of the muzzle brake assembly 10 can therefore be adjusted.
- the efficiency of the modular muzzle brake assembly 10 can be adjusted by adjusting the spacing between adjacent baffles 30 in the muzzle brake assembly 10, for example, by adjusting the length and/or number of spacers 50 between adjacent baffles 30.
- the efficiency of the modular brake assembly 10 can be adjusted by adjusting the orientation of one or more of the baffles 30.
- the efficiency of the baffles 30 may be controlled by adjusting whether the baffles 30 face in a first direction (e.g. with a first end of the baffles 30 facing towards the gun barrel 3) or in a second direction (e.g. with the first end of the baffles 30 facing away from the gun barrel 3).
- the efficiency of the modular muzzle brake assembly 10 can be adjusted by adjusting the order of the baffles 30 within the muzzle brake assembly 10.
- one or more of the baffles 30 may be configured to divert the propellant gas in a more efficient manner than at least one other of the baffles 30, for example, diverting a greater volume of propellant gas and/or diverting the gas at a greater angle of diversion.
- the more efficient baffle(s) 30 can be provided within the assembly 10 such that the baffle(s) are closer to the gun barrel 3, which will increase the recoil efficiency of the muzzle brake assembly 10.
- the less efficient baffles(s) 30 can be provided within the assembly 10 such that the baffle(s) are closer to the gun barrel 3, with the more efficient baffle(s) 30 located further away from the gun barrel 3, which will decrease the recoil efficiency of the muzzle brake assembly 10.
