摘　　要：通过数值方法求解三维可压缩雷诺平均N-S方程,对导弹横向喷流的干扰流场进行了数值模拟,计算结果与实验数据吻合较好,基本验证了计算方法在横向喷流复杂流场数值模拟方面的有效性。在此基础上,对固定尾翼鸭式布局导弹亚、跨、超声速流场进行了数值模拟,并且计算分析了横向喷流对鸭式布局导弹滚转控制特性的影响,计算结果表明,横向喷流可以有效提高鸭式布局导弹的滚转控制能力。The subsonic, transonic and supersonic flow fields are simulated for a canard mis- sile by solving the 3-D, compressible N-S equations. The capability of the canard missile is main- ly restricted by rolling control characteristics. The lateral jet interaction field structure is ob- tained by numerical simulation. Comparison of CFD results with experiment date shows that the numerical method is accurate and stable in lateral jet interaction field simulation. Then the re- search of lateral jet interaction for rolling control of the canard missile is simulated, it shows that the rolling control characteristics of the canard missile can be imoroved by lateral iet.
