Gun muzzle brake

Abstract

A concave surface at the front end of a gun facing the gun muzzle is tilted upwardly to redirect propelling gas rays to a venting port or ports adjacent the gun muzzle for virtual recoil neutralization. In the case of a single port at the top of the expansion chamber, not only axial recoil but also vertical recoil are virtually neutralized. In a dual-port arrangement, two ports (one on each side of a vertical plane through the axis of the expansion chamber) are provided with two concave surfaces tilted upwardly and outwardly to separately redirect rays of propellant gas through each of the two ports which are positioned with the extent of the area of each port above a horizontal plane through the axis of the expansion chamber determined empirically to provide neutralization of both vertical and horizontal recoil as well as axial recoil. Each concave surface for the dual-port arrangement is thus tilted up and to one side of the expansion chamber axis.
