膛口制退器对后效期膛内压力的影响分析

摘要

基于某12.7 mm机枪内弹道参数，通过MATLAB语言进行编程，对火药气体对后坐部分的后效期进行研究。对比在有、无膛口装置时膛内压力变化，得出膛口制退器对减小武器的后坐动能和射击载荷有一定影响。%Based on the trajectory parameters of a 12 .7mm machine gun ,by MATLAB language programming ,the influence of gunpowder gas on recoil part in aftereffect-period was studied .The breech pressure changes in the presence or absence of muzzle device were compared .The result shows the muzzle brake may have a certain influence on reducing the kinetic energy of weapons and shooting loads .
