Abstract
A muzzle brake for a large or medium caliber barrel. The muzzle brake has a body whose inner dimensions are substantially greater than those of the barrel and which is fitted with at least one stage of two openings prolonged by vanes upon which the propellant gases are applied to create a force in the opposite direction to that generated by these gases. The muzzle brake comprises a tubular component prolonging the free end of the barrel, that is engaged in the body and pierced with several vents directing the propellant gases towards the vanes. The diameter of the tubular component is roughly between the caliber of the barrel and the diameter at the bottom of the rifling grooves of the barrel.
Claims13
A muzzle brake for a barrel, the muzzle brake comprising:
- a body including an inwardly-facing frustoconical part extending from an end of the barrel and having an inwardly-facing slope diverging relative to an axis of the barrel followed by an inwardly-facing converging part upon which propellant gases are directed to create a force in a direction opposite to a force generated by the propellant gases;
- and
- a tubular component prolonging a free end of the barrel engaged within the body, the tubular component being pierced with a plurality of vents extending along an axial direction of the tubular component for directing the propellant gases towards the converging part, the vents being inclined by an angle relative to the axis of the barrel that is substantially equal to the inwardly-facing diverging slope of the frustoconical part of the body.
A muzzle brake for a barrel, the muzzle brake comprising:
- body means for directing propellant gases to create a force in a direction opposite to a force generated by the propellant gases, the body means including an inwardly-facing frustoconical part extending from an end of the barrel and having an inwardly-facing slope diverging from an axis of the barrel followed by an inwardly-facing converging part upon which the propellant gases are directed;
- and
- tubular means for prolonging a free end of the barrel engaged within the body, the tubular means being pierced with a plurality of vents extending along an axial direction of the tubular component for directing the propellant gases towards the converging part, the vents being inclined by an angle relative to the axis of the barrel that is substantially equal to the inwardly-facing diverging slope of the frustoconical part of the body means.
