埋头弹火炮高效低危害炮口制退器的实验研究

摘要

为降低埋头弹火炮发射过程中炮口制退器产生的冲击波危害,设计了高效低危害炮口制退器的实验装置.通过对比射击实验,将新型高效低危害炮口制退器与原炮口制退器性能进行了对比.实验结果表明:高效低危害炮口制退器能够有效减小火药燃气的侧向流动;同时降低流场中冲击波的强度,炮手位置冲击波强度减小了61.4％,大大降低了射击过程中冲击波对炮手的危害.在高效低危害炮口制退器基础上使用了消声碗,虽然炮口冲击波强度略有增强,但制退器的制退效果得到显著改善.%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.
