Progress Report on the Study of the Effect of Muzzle Brake Design on the Recoil of Guns, 1

Abstract

A caliber .50 ballistic pendulum for measuring the efficiency of various nuzzle-brake designs is described. The effect of: (1) baffle spacing, (2) nozzle angle, (3) diffuser-cone angle and (4) outlet (reversal) angle has been determined. The results show that: (1) There is not much gain in efficiency when the baffle spacing exceeds a 1-in. opening (2 calibers). (2) A nozzle angle of 30 deg with a baffle spacing of 1 1/4 in. is the most efficient. (3) A diffuser cone is not necessary to obtain greater efficiency in brake action. (4) A flat baffle is more efficient than a baffle having any degree of reversal angle up to 60 deg.
