文中为了研究方形截面导弹的气动特性,设计了舵面位于平面和舵面位于直角两种布局形式方形截面导弹,并通过CFD数值模拟方法分析比较了方形截面导弹和圆形截面导弹的气动特性。分析结果表明,方形截面导弹相比圆形截面导弹具有较大的法向力和横、侧向气动力,其中舵面位于平面布局与舵面位于直角布局的方形截面导弹相比较其横、侧向气动力要小一些。

In order to investigate aerodynamic characteristics of square cross-section missile, square cross-section missile with fin plane and, and then the aerodynamic characteristics of square and circular cross-section missile through CFD numerical simulation. The result indicates that the square cross-section missile can generate more normal force and lateral force and moment than the circular cross-section missile, and the square cross-section missile with fin plane can generate less lateral force and moment than the square cross-section missile with fin.
