A Stress Factor Method for Perforated Muzzle Brake Design

Abstract

A perforated muzzle brake consists of a set of vents drilled through the wall of a cannon near the muzzle to reduce the impulse transmitted to the mount. The vented structure must support both the tube pressure and the pressure acting on the vent surfaces that produces the braking force. This report presents a method for estimating the maximum Von Mises stress within the structure. The results agree to within 10 percent of those from a more detailed finite element calculation.
