doi:10.3969/j.issn.1000-1093.2017.05.025

Abstract

Abstract: To reduce the hazard of shock wave induced by muzzle brake during the launching process of cased telescoped ammunition (CTA) gun, a high efficiency and low hazard muzzle brake is designed. The high efficiency and low hazard muzzle brake is compared with the traditional muzzle brake through launching experiment. The experimental result indicates that the high efficiency and low hazard muzzle brake can be used to effectively restrict the lateral flow of combustion gas, weaken the shock wave in the flow field greatly, and reduce the intensity of shock wave at the location of launcher by 61.4%, which reduces the harm of shock wave to gunner. Although the intensity of shock wave is slightly enhanced after a silencing bowl is used in the high efficiency and low hazard muzzle brake, but the recoil performance of launching system is significantly improved.
