战术导弹组合舵效数值仿真研究

The Numerical Simulation and Research of Combined Fin-deflection Efficiency of Tactical Missile

为更好的设计战术导弹控制系统,有必要研究不同通道舵面效率的情况。文中采用结构重叠网格数值仿真方法,得到多种组合舵偏状态导弹绕流外流场,重点分析了俯仰通道舵偏角的存在对滚转通道舵效的影响。结果表明,中等俯仰通道舵偏角的存在会对滚转通道舵效产生较大的影响,而滚转通道舵偏对俯仰通道舵效影响并不明显。

For better design of tactical missile＇s control system, it is crucial to study the fin-deflection efficiency of respective channel. In this paper, the numerical simulation method based on structured overlapping grids was applied to get outer flow field around the missile with combined fin deflection. The effect of fin deflection of pitch channel on roll channel was emphatically analyzed. The results show medium fin deflection of pitch channel can make considerable effect on fin-deflection efficiency of roll channel, while fin deflection of roll channel affects little on pitch channel.
