FIELD OF THE DISCLOSUREThe subject matter of the present disclosure refers generally to flash suppressor assemblies for weapons.
BACKGROUNDA flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle. The flash suppressor reduces the chances that the shooter will be blinded in low-light shooting conditions. Secondarily, the flash suppressor reduces the intensity of the flash visible to others, as for example, enemy combatants.
Flash is more prevalent with shorter length barrels commonly used with today's firearms. Flash can be a serious problem during night-time combat because the flash interferes with the shooter's night vision and may make the shooter's position more apparent. Flash suppressors are designed to reduce the muzzle flash from the weapon to preserve the shooter's night vision by diverting the incandescent gases to the sides, away from the line of sight of the shooter, and to secondarily reduce the flash visible to the enemy. Military forces engaging in night combat are still visible when firing, especially with night vision gear, and must move quickly after firing to avoid receiving return fire.
Flash suppressors reduce, or in some cases eliminate, the flash by rapidly cooling the gases as they leave the end of the barrel. Although the overall amount of burning propellant is unchanged, the density and temperature are greatly reduced, as is the brightness of the flash.
Despite developments in flash suppressor technology, the need still remains for an improved flash suppressor that reduces or eliminates flash.

In operation, flash suppressor assembly 10 is detachably secured to the muzzle of barrel 12 of weapon 14. A shooter fires weapon 14 causing the projectile in the chamber to be expelled into barrel 12 and travel from barrel 12 into flash suppressor assembly 10. The projectile may be a cartridge consisting of a bullet housed in a case. Propellant such as gunpowder, cordite or other explosive and combustible material may be contained in the case behind the bullet. The cartridge may also contain a rim and primer at its actuation end. Actuating the primer by firing weapon 14 ignites the propellant that causes the firing of the bullet that travels through the barrel 12. The gases behind the bullet are combustible and may cause flash (unless suppressed) as the bullet exits the barrel 12.
With the flash suppressor assembly 10 in place on the muzzle, the bullet and hot gases are expelled into the receiver 22. The bullet will travel along the pathway provided by the contiguous bore walls of the receiver and burn tube 54, 72 until the bullet is expelled at the other end of the flash suppressor assembly 10. With the internal configuration of the flash suppressor assembly 10, the combustion gases entering receiver 22 will flow from the bore wall 54 through openings 62 and into first chamber defined by first section 102 of tubular burn chamber 32 and side wall section 52 of receiver 22. After being received in first chamber 162, the combustion gases flow to second chamber 164. Second chamber 164 is defined by second section 108 of tubular burn chamber 32 and part of side wall section 52 and end 42 of burn tube 34. Due to the tapered profile of second section 108 and the increased outer diameter area of end 42, chamber 164 has a reduced volume area in relation to chamber 162 that causes compression and acceleration of the combustion gas as it travels through second chamber 164 to third chamber 166. The third chamber 166 is defined by third section 114 of tubular burn chamber 32 and tapered first section 76 of burn tube 34. Due to the decreasing tapered profile of the outer diameter of tapered section 76 and the expanding profile of the inner diameter of the third section 114 of tubular burn chamber 34, the volume area contained within third chamber 166 is greater than the volume area of the second chamber 164. Accordingly, third chamber 166 is an expansion or burn chamber that permits the compressed/accelerated combustion gases flowing from second chamber 164 into third chamber 166 to expand, mix with oxygen, and burn. The wave-form or undulating profile of the outer surface 74 of burn tube 34 (e.g., grooves 88) acts to disrupt the gas and facilitate intermixing of the combustion gas with oxygen to advance the burning thereof. While the flash suppressor assembly 10 shown in
With reference to
After the gases are burned and cooled within the fourth chamber 168, the burned/cooled gases flow into fifth chamber 172. Fifth chamber 172 is defined by fifth section 122 of tubular burn chamber 34 and end section 174 of tapered third section 84 of burn tube 34. Due to the increasing tapering of end section 174, the gases in fifth chamber 172 may be slightly compressed as they flow through fifth chamber 172. Fifth chamber 172 is configured to reduce the flow speed of the gases before they exit through gas vents 26 and are expelled into the atmosphere in a direction away from the shooter's line of sight.
The component parts constituting flash suppressor assembly 10 may be made of any heat durable material. For example, the component parts may be made from steel or other hard metal. The component parts may be composed of a composite material capable of withstanding combustion of the exhaust gases. Burn tube 34 may be composed of 4140 steel or titanium.
Flash suppressor assembly 10 may be sized in a variety of dimensions. For example, the outer diameter of flash suppressor assembly 10 may be about 2.25 inches. The length of flash suppressor assembly 10 may be in the range of 10-12 inches or about 10 inches.
Tubular burn chamber 32 may have an outer diameter in the range of about 2 inches and about 2.145 inches at face 130. The inner diameter of tubular burn chamber 32 may varying from about 1.5 inches to about 1.375 inches. For example, section 102 may have an inner diameter of about 1.5 inches, section 108 may have an inner diameter with a gradient or slope from about 1.5 inches to about 1.375 inches to about 1.5 inches, section 114 may have an inner diameter of about 1.5 inches, section 118 may have an inner diameter of about 1.5 inches, and section 122 may have an inner diameter of about 1.5 inches. Tubular burn chamber 32 may have an overall length of about 9.281 inches. Section 102 may have a length of about 1.5 inches, section 108 may have a length of about 1.250 inches, section 114 may have a length of about 1.250 inches, section 118 may have a length of about 4 inches, section 122 may have length of 1.25 inches.
Burn tube 34 may have a length of about 7.816 inches, an outer diameter in the range of 0.551 inches to 1.070 inches. Bore wall 72 may have diameter of 0.312 inches. Tapered first section 76 may have a length of about 2.109 inches with a gradient or slope from about 1.070 inches to about 0.645 inches. Tapered second section 80 may have a length of about 2.5 inches with a gradient or slope from about 0.938 inches to about 0.705 inches. Tapered third section 84 may have a length of about 2.5 inches with a gradient or slope from about 0.705 inches to about 0.938 inches. End 40 may have a length of about 1.0 inches and an outer diameter of about 0.551 inches. Grooves 88 may have a depth of about 0.625 inches or ⅝ inches and a width of about 3/16 inches. The dimensions of grooves 88 may varying within and/or between sections 76, 80 and 84. For example, the depth of grooves 88 in section 76 may gradually lessen as the grooves 88 progress to point 78. Similarly, the depth of grooves 88 in section 80 may gradually lessen as the grooves 88 progress from point 78 to point 82. The depth of grooves 88 in section 84 may gradually increase as the grooves progress from point 82 to point 86. The number and dimensions of grooves 88 control the timing of gas speed and create more turbulence in burn tube 34 to cool the gases. Grooves 88 disrupt the gas flow through burn tube 34 and slow down the forward movement of the gases in a delaying time ratio of about 3 to 1 by fluid volume. The smooth section of bore wall 72 may have a length of about 2.316 inches. The threaded section of bore wall 72 may have a length of about 5.50 inches.
Flash suppressor assembly 10 operates by providing receiver 22 that receives hot gases when a projectile is fired and distributes the hot gases to one or more sets of contracting/compression chambers and expansion/burning chambers with one or all of the chambers containing at least one rippled surface to permit the gases to intermix with oxygen to enhance burning. Optionally, a screw or spiraling chamber may be provided to circulate the hot gases to allow for complete burning in a spiraling fashion before the burned gases exit to the atmosphere through vents 26 in the end cap 20. Optionally, insulating sleeve 30 may be provided between outer sleeve 16 and tubular burn chamber 32 to keep the heat generated by the burning of the gases within the burn chambers to further enhance and promote the complete burning of the gases.
Although the foregoing disclosure has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be obvious that certain changes and modifications may be practiced within the scope of the appended claims.
