Abstract
The present disclosure relates to a modular muzzle brake assembly for an artillery weapon or cannon. The modular muzzle brake assembly comprises 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. The plurality of modules include a plurality of baffles configured to divert at least a portion of the propellant gas in the passage. The present disclosure also relates to a kit of parts for a modular muzzle brake assembly.

A modular muzzle brake assembly for an artillery weapon or cannon, the modular muzzle brake assembly 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;
- wherein a gap is provided between at least two of the baffles such that at least a portion of the propellant gas in the passage can pass through the gap;
- wherein at least one of the baffles includes a first baffle member and a second baffle member, the first baffle member having a first flow control surface and the second baffle member having a second flow control surface;
- and
- wherein the propellant gas flowing out of the passage via the gap impinges on the first and second flow control surfaces.
A kit of parts for a modular muzzle brake assembly for an artillery weapon or cannon, the kit of parts 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;
- wherein a gap is provided between at least two of the baffles such that at least a portion of the propellant gas in the passage can pass through the gap;
- wherein at least one of the baffles includes a first baffle member and a second baffle member, the first baffle member having a first flow control surface and the second baffle member having a second flow control surface;
- and
- wherein the propellant gas flowing out of the passage via the gap impinges on the first and second flow control surfaces.
A modular muzzle brake assembly for an artillery weapon or cannon, the modular muzzle brake assembly 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;
- at least one coupling member to couple the modules together, the modules being releasable from the at least one coupling member;
- and
- a mounting portion configured to couple to a gun tube of the artillery weapon or cannon;
- wherein one or more of the baffles comprises a receiving portion configured to receive part of the at least one coupling member;
- wherein a gap is provided between at least two baffles of the assembly such that at least a portion of the propellant gas in the passage can pass through the gap;
- wherein at least one of the baffles comprises first and second baffle members, and a space is disposed between the first and second baffle members, so as to provide the at least one baffle with a hollow structure;
- wherein the length of the passage is adjustable by altering the number of modules of the modular muzzle brake assembly;
- wherein at least two of the baffles are interchangeable within the muzzle brake assembly;
- wherein diversion of the propellant gas along the passage is adjustable by altering a baffle type of one or more of the baffles relative to one or more other of the baffles;
- wherein the first baffle member has a first flow control surface and the second baffle member has a second flow control surface, and
- wherein the propellant gas flowing out of the passage via the gap impinges on the first and second flow control surfaces.
