摘　　要：用数值模拟方法研究侧喷流对炮射导弹气动特性的影响.以三维N-S方程为出发方程,采用S-A湍流模型,对炮射导弹的绕流场进行了数值模拟研究,得到的气动特性结果与风洞实验结果基本吻合.在此基础上,对含侧喷流炮射导弹的绕流场进行数值计算.结果表明,侧喷流对导弹气动特性有较大影响.The method of numerical simulation was used to investigate the influence of the side jet flow on the aerodynamic characteristics of gun-launched missile. Based on three-dimension N-S equations combined with S-A turbulence model, the numerical simulation of computational fluid dynamics （CFD） was implemented. It is found that the computational aerodynamic characteristics are to be in good agreement with the results from wind tunnel test. The numerical simulation for external flow field of gun-launched missile with side jet flow was performed. The result from simulating performance also shows that the side jet flow have significant influence on the flow field and the aerodynamic characteristics of gun-launched missile.
