Abstract : Tests were conducted at the Ballistic Research Laboratory for a 20mm perforated muzzle brake. Six muzzle brake designs were analyzed for their influence on muzzle velocity, blast overpressure, and brake efficiency. The designs were a combination of scaled versions of 105mm and 120mm muzzle brakes and new designs that were fabricated to reduce blast overpressure at the breech. Certain designs were tested to verify computer predictions that upstream venting in a muzzle brake could reduce the blast overpressure at the breech.
