The Effects of a Muzzle Brake's Diameter and Length on Overpressure and Efficiency
Abstract
This is an interim report on an overall study of single and multi- baffled brakes. The intent of this study is to isolate and examine each muzzle brake parameter to determine its effect on efficiency and overpressure for the purpose of developing an optimum brake geometry which will maintain efficiency and reduce overpressures on the crew area. The parameters with which this test dealt were the brake's deflector diameter and its location with respect to the muzzle. The most important finding of this study is that there exists a downstream loci of points between 1.5 and 2.5 calibers at which a baffle can be placed and maintain a relatively constant efficiency and that at 2.5 calibers, a baffle will produce almost 16 percent less overpressure than it does at 1.5 calibers. This optimum geometry in which a reduction in overpressure is obtained without loss of efficiency can be applied to all conventional brakes.
