摘　　要：为了深入了解垂直发射装置内流场结构,应用数值计算的方法对导弹垂直发射系统燃气射流流场进行了仿真模拟,并对垂直发射燃气排导系统内压强的分布情况进行分析;结果表明:导弹发射的过程中,起始冲击波在燃气排导系统内具有较高的超压峰值,燃气流的最大压力载荷出现在发射位压力室底部,为垂直发射装置的结构设计优化工作提供重要的理论基础。In order to understand the flow field structure of vertical launching devices, the flow field in the vertical launching system was calculated by the method of numerical calculation and then was simulated. The pressure distribution of the flow field was analyzed minutely. The result summed up that the initial shock wave has ultrahigh pressure and the maximum pressure appeares in the bottom of the pressure box during firing. The result provides important theoretical basis for the structure design of work.
