摘　　要：为了探究某内能源转管武器导气装置内部流场的情况,本文建立了某内能源转管武器导气装置气室流场的物理模型和数学模型,利用计算流体力学软件数值模拟了导气装置的气室流场,得到导气前、开始导气与结束导气三种时刻下导气装置的压力云图、温度云图以及速度流线图,总结其规律并分析导气孔处温度和压力的情况,为今后内能源转管武器的结构设计提供参考价值。In order to explore some cases of internal flow field of gas-operated device structure parameter in internally-powered gatling weapon system,the physical model and mathematical model of flow field in gasoperated chamber of gas-operated device structure parameter in internally-powered gatling weapon system were established. The CFD was used to simulate the flow field in gas-operated device,get the pressure nepho--gram,temperature nephogram and velocity flow chart under the three moments of before gasoperated,begin gas-operated and over gas-operated. Summarize the regular and analyze the situation about temperature and pressure at the gas-operated hole,It will provide a reference for the gas-operated device structure parameter in an internally-powered gatling weapon system.
