某小型战术导弹弹顶反安定面布局设计研究

The Layout Designof Anti-stable Wings on the Top of a Small Tactical Missile

为了权衡某小型战术导弹的静稳定性和操纵性,在不改变弹体直径的前提下,将反安定面布置在弹顶。利用气动仿真计算分析了反安定面及其数量对导弹气动参数和静稳定度的影响,结果表明,反安定面可显著改善弹体气动特性和静稳定度。

In order to balance the small tactical missile＇s static stability and maneuverability,the anti-stable wings are assembled on the top of missile with the prerequisite that no change of body diametric.The influence of the anti-stable wings and number on the main aerodynamic parameters and static stability was analyzed based on the aerodynamic simulation.The simulation results indicate that the body aerodynamic characteristics and the static stability are significantly improved by the small anti-stable wings.
