Silencers, while designed to mitigate the loud sound of gunfire, can also suppress muzzle flash. Ammonium chloride and ammonium nitrate salts have also been tried with success. The side effects of the alkali salts are a reduction in power, an increase in smoke, and fouling and corrosion of the firearm and nearby equipment (a significant concern with aircraft guns). In both cases, the salts act as catalysts, and interfere with the hydrogen-oxygen combustion to reduce the muzzle flash. Addition of a few percent of alkali salts to the powder for flash suppression is common, typically salts of potassium such as potassium chloride, potassium sulfate, potassium carbonate and potassium bicarbonate. In World War I, bags of sodium chloride (table salt) were placed in front of the propellant charges of artillery to suppress the flash. However, since the primary cause of the secondary flash is combustion of hydrogen and carbon monoxide, chemical approaches are also used.

įlash hiders attempt to suppress the flash mechanically, by interfering with the blast wave using either a cone or a series of slots at the muzzle of the firearm. Ingestion of the muzzle flash from aircraft-mounted guns has also been implicated in compressor stall and flameout, causing loss of aircraft. Due to its brightness, muzzle flash can temporarily blind the shooter, or give away the shooter's location, especially at night. Muzzle flash, particularly the longer-duration secondary flash, is an inherent problem in most firearms. Technology is being developed to detect enemy muzzle flashes before the projectile reaches its target. Muzzle flashes create distinct signatures that can be located using infrared imaging technology. dislodged lead, copper and/or carbon foulings) can be further ejected from the muzzle and appear as airborne residual sparks.

Following the dissipation of the muzzle flash, partially unburnt powder or other heated materials (e.g.

The secondary flash appears farthest from the muzzle as a large white or yellow fireball, and is caused by a newly ignited oxidation of incompletely combusted ejecta when mixed with abundant oxygen in the surrounding atmosphere.

The intermediate flash is caused by shock waves created by the high speeds of the escaping gases and projectile, and appears as a reddish disc-shaped in front of the muzzle.

Although amongst the brightest of the flashes, the heat of the primary flash dissipates very quickly, and thus is usually not distinctly noticeable.

The primary flash is caused by superheated propellant gases exiting the firearm behind the projectile, which radiates its energy to the surroundings partly as visible light.

It glow is created by superheated gases that have leaked past the projectile and have exited the barrel ahead of it. The muzzle glow is a reddish glow that is visible before the bullet leaves the barrel.Muzzle flash can be broken down into five distinct components. Note the minor flash at the gap between cylinder and barrel. The size and shape of the muzzle flash is dependent on the combustion energy of propellant being used, the amount of combustible ejecta remaining, and any devices attached to the muzzle (such as a flash hider, suppressor or muzzle shroud).Ĭharacteristics Muzzle flash of a revolver.

Both the blast and flash are products of the exothermic combustion of the propellant ( gunpowder), and any remaining unburned powders reacting with ambient air. Muzzle flash is the light - both visible and infrared - created by a muzzle blast, which is caused by the sudden release and expansion of high-temperature, high-pressure gases from the muzzle of a firearm during shooting.
